Answer:
Restriction endonucleases are utilized to cut the deoxyribonucleic acid at a specific Restriction site. HindIII is an example of Restriction endonuclease. The Restriction site of HindIII is as per the following:
5'A*AGCTT3'
3'TTCGA*A5' (* represents restriction site)
The Restriction endonuclease cuts the particular gene from the foreign DNA and produces numerous fragments with the sticky ends. The part of the outside DNA which contains the gene of intrigue or a particular gene is ligated with the plasmid.
On the off chance that foreign DNA and plasmid DNA are separated by the same Restriction endonuclease, they will create sticky ends integral to one another. In this way, the segment of foreign DNA can be ligated to the plasmid DNA by the assistance of DNA ligase at the integral sticky end to shape a recombinant DNA.
Additionally, by the assistance of the same Restriction endonuclease for example HindIII for this situation, the recombinant plasmid can be treated with a similar Restriction endonuclease to extract the ideal gene or gene of intrigue.

Explanation:
Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rate of 15 per 1,000/yr, and an emigration rate of 8 per 1,000/yr. What is the population growth rate
Answer:
0.023%
Explanation:
The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula
[tex]N/t[/tex] where N is the total change in the population size, and t is time.
When immigration and emigration are factored in, we now have the formula;
[tex](CBR +I) - (CDR + I)/1000[/tex]
[tex]= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\[/tex]
g 1 molecule of glucose is catabolized to pyruvate and then acetyl-coA. All the acetyl-coA enters the citric acid cycle. How many molecules of NADH are produced from the citric acid cycle only (do not include NADH from glycolysis or the pyruvate dehydrogenase complex in your calculation.) You must answer as a number i.e if you think the answer is 12, you must enter 12, not twelve.
Answer:
6NADH
Explanation:
In the kreb's cycle NAD is reduced during the reduction of 6-carbon citrate to 5 carbon Alpha-Ketoglularate.
The second is produced during the conversion of 5carbon alpha ketoglutarate to succinate. Lastly in the conversion of fumirate to oxoloacetate;another NADH is formed.
However, since two pyruvate enters the Kreb's cycle therefore 6NADH(three NADH per cycle of Citric) are produced for each molecule of glucose that is broken down from glycolysis.
Remember,each glucose molecule goes through 2 cycles of Kreb.
Futhermore co-enzyme FADH2 are also produced,with 2 molecules per 1 glucose.
These Co-ezymes transfer hydrogen ions,into the matrix of the mitochondria,where is is splits to protons and electrons.
The electrons formed the ETC,which produce PMF for transporting protons into the intramembranes for electrochemical gradients needed to generate energy for ATP s synthesis,by ATP synthase.

Answer:
Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.
Incomplete dominance: Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.
Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.
Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.
Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.

Reset
Next
Answer:
Meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does
unicellular organisms.
Explanation:
Meiosis is a kind of cell division used mainly by sexually-reproducing organisms, whether unicellular or multicellular, to produce gametes i.e. meiosis only occurs during gamete formation.
In sexual reproduction, gametes must fuse in a process called fertilization. This gametes, however, must each possess half of the chromosome number of the individual organism. Meiosis is the process that ensures that the chromosome number of the gametes is reduced by half i.e. diploid (2n) to haploid (n).
Therefore, meiosis is the process of gamete formation in sexually-reproducing unicellular or multicellular organisms.
Mutations in region B and region D give the same results - when either of these regions is mutated, the operon is expressed under all conditions (called constitutive expression). You hypothesize that region B is the operator region and that Region D is the repressor protein. To test your hypothesis, you create two partial diploid lines by introducing a F' plasmid with a wild-type lac operon: Strain 1: F' A B C D E / A B- C D E Strain 2: F' A B C D E / A B C D- E What experimental results would be predicted by your hypothesis
Answer:
As it is given in the question that region D is the repressor protein and operator region is region B then the The repressor region D form a protein that will bind to the operator region B and leads to inhibition of the transcription. So, the repressor protein will not repressed a mutant operator and the lac gene will express itself constitutively.
Strain 1: F' A B C D E / A B- C D E
In this strain the mutant opertor gene is present so, it will not repressed by F' as it will not be able to bind. Hence, the lac gene expression is constitutive.
Strain 2: F' A B C D E / A B C D- E
In this strain there is two protein produced by the F' plasmid mutated repressor protein, and a non-mutated repressor protein. As we know mutated repressor will not bind to operator gene and still expression will take place but here a extra not mutated non-mutated protein is present and the repressor protein from F' will bind to the operator region B and thus repress the expression of gene in it.
In pea plants, purple flower color, C, is dominant to white flower color, c. The table shows the frequencies of the dominant and recessive alleles in three generations of peas in a garden. Allele Frequency for Flower Color in Peas Generation p q 1 0.60 0.40 2 0.64 0.36 3 0.75 0.25 4 0.80 0.20 Which generation showed the greatest frequency of having one of each allele? generation 1 generation 2 generation 3 generation 4
Answer:
generation 1
Explanation:
The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.
In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.

What can a person do to limit exposure to X-rays?
wear sunblock
avoid cigarette smoke
wear a protective vest avoid chemicals
X-rays are a form of indirectly ionizing radiation, and it can be really nocive to the humans health, so limiting the exposure is always a priority.
Here the correct option is wearing a protective vest.
-------------------------------------
X-rays are a form of radiation that is indirectly ionizing. Remember that ionization is what causes damage to our cells, so is better to avoid exposures to these types of radiation.
Now, X-rays are strong enough that they can penetrate a lot of common materials (like wood, plastic, etc.) And once it enters in your body, the chain of reactions that starts can't be stoped by external means.
So what you need to do is limit the exposure as much as you can. Ideally, you shouldn't be near a source of X-rays, but if there is no other option, you should use protection against radiation.
It comes in different forms depending on what the application is, for example, there are led screens that you can use to put between you and the source, and these will reduce drastically the fluence (flux of photons) that gets to you.
Similarly, there are protective vests also made in part of led or other high atomic number materials, that absorb the photons and protect you.
So here the correct option is to wear a protective vest, from the given options, is the only one that will protect you from the X-rays.

Which of the following best describes the flow of energy in the Everglades food web shown below? (4 points) Diagram for an everglades food web. The food web contains the following organisms: American alligator, egret, raccoon, carp, Key deer, insects, Southern leopard frog, mangrove, and sawgrass. Mangrove is at the bottom of the food web, with arrows pointing to Key deer and insects. Sawgrass is also at the bottom of the web, with an arrow pointing to insects. Key deer, insects and Southern leopard frog are on the next level up. The Key deer has an arrow pointing to American alligator. The insects point to egret, carp, and Southern leopard frog. The Southern leopard frog points to the American alligator and the raccoon. The egret, carp and raccoon all points upward toward the American alligator. The carp also points to the egret. The American alligator is at the top of the food web. Mangrove → insects → carp → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level. Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level. American alligator → carp → insects → mangrove; about 10 percent of the energy in one trophic level is transferred to the next trophic level. Egret → insects → mangrove → key deer → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.
Answer:
Although there is no diagrammatic representation of the food web but the question can be answered based on the provided information. The answer is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Explanation:
Food web is an interconnected food chain i.e. a series of food chains clustered together. A food web represents the various ways one organism can feed on another in a cycle. Since a food web consists of many food chains, energy is transferred when one organism feeds on another (flow of energy).
Just like a food chain, a food web begins with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. This is the case of mangrove and sawgrass in this depicted food web as they are both producers and hence, must start the food web i.e. be at the bottom of the food web. Organisms called CONSUMERS feed on producers and one another to obtain energy. Consumers can be primary, secondary or tertiary depending on the organism they feed on. Primary consumers feed directly on producers, secondary consumer on primary and tertiary consumers on secondary, in that order.
This accounts for why the American Alligator is at the top of the food web because it is a tertiary consumer.
However, as organisms feed on one another, only about 10% of the available energy is transferred because most of the energy (about 90%) has been used for metabolic processes and hence, lost as heat.
Therefore, the best description for the flow of energy in the Everglades food web is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Sawgrass is the producer and must begin the energy flow, followed by a primary consumer (insect). Feeding continues in that order until the tertiary consumer (American alligator) is reached.
Answer:
b) Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure evidence of changing environmental conditions, with references the reasons competing hypotheses are wrong his opinion of what will happen to the survival of the human race
Answer:
Dr. Potts used environmental data to support environmental hypotheses capable of explaining human evolution
Explanation:
In this paper, the author stated that environmental factors have been fundamental for the emergence of adaptive traits during human evolution. In consequence, Dr. Potts explained how particular environmental factors and habitats might have shaped human evolution. For example, it has been hypothesized that dry savanna vegetation might have been a key environmental factor associated to the emergence of human traits including, among others, bipedality, making of tools from stones, the development of human brains, etc. In order to prove this hypothesis, the author recorded environmental data from different regions in Africa (Olorgesailie, Olduvai, Turkana, Zhoukoudian, etc), where it is believed that first hominids evolved about 6-8 million years ago.

Which of the following is a human-related release of greenhouse gases?
O A. Wild animal respiration
OB. Volcanic eruptions
O C. Intensive agriculture
O D. Solar cycles
It’s A
Answer:
C
Explanation:
I'm pretty sure it's actually C and not A. It's asking for human-related release from greenhouse gases. Humans don't cause volcanic eruptions and aren't in control of wildlife's respirations. The solar cycles has to do with the magnetic flux that rises to the surface of the sun and lasts 11 years. Intensive agriculture increases pollution which harms the environment.
How can changes on earths surface affect changes below surface
Answer:
There are several changes that occur on the earth's surface but also affects the changes below the surface, some of them are as follows:
When rainfall occur on the sandy surface on earth, it looses the soil under the surface and can cause landslides.Imbalance in the food chain above or on the earth surface can affect the nutrient quantity below the surface that is essential for soil bacteria and other microorganisms.Deforestation can also loosen the soil and soil under surface can shift its position.Use of chemicals on agriculture surface can lead to change the fertility of soil below the surface.botanical name for fals yam

Drag each tile to the correct box. Arrange the stages of the frog’s life cycle from first to last. ↓ ↓ ↓ ↓
You didn't put the answer options, but the frog life cycle phases are:
Mating: In this phase two adult frogs, a male and a female, mate in the water or on plates. At this point, the male frog wraps his arms around the female and overlaps over her back. Spawning: At this point, the female releases the eggs into the water, ready to be fertilized by the males. Fertilization occurs outside the female's body. Eggs: Some fertilized eggs will be devoured by small animals, but those that survive will hatch 7-9 days after fertilization, releasing a frog shape, called a tadpole.Tadpole: It is similar to a fish and is formed by tail, mouth and gills. After 7 days of life, you will be able to swim and feed on algae. Four weeks later he will develop teeth and skin. When he reaches 9 weeks he will begin to change his shape, growing in size and developing head and legs. At that moment it will look more like a frog, but it still has a long tail. Metamorphosis of the fish: Up to twelve weeks of age it will reach the shape of a frog and start to feed on insects. Gradually it will lose its tail and its tongue will grow. The 16 weeks will become an adult frog, being able to mate and restart the cycle.Answer:

Explanation:
) Recall what you know about crossing over, independent assortment, and random joining of sex cells during sexual reproduction.
Answer:
Crossing over is the process of interchange of genetic information among non-sister chromatids of homologous chromosome pairs during meiosis (specifically during synapsis in prophase I). During this process, the synaptonemal complex enables the interchange of chromosome fragments between non-sister chromatids through crossing over. Moreover, in sexual reproduction, the zygote diploid cell can be generated by the random joining of fully differentiated haploid gametic cells (male and female gametes). The combination of random joining with the phenomenon of crossing over is known to considerably increase the genetic variation of the resulting offspring. After zygote formation, the successive cycles of cell divisions during embryonic development will develop an organism that during its adult stage will reproduce via sexual reproduction.
Phytoplankton, shown on the left in the image below, are microscopic organisms that can be found in freshwater and salt water environments. They perform photosynthesis to get energy and act as an important food source for larger organisms, such as the whale that is shown on the right. Phytoplankton A large whale. Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
The whale is heterotrophic.
Explanation:
Energy is needed by organisms to perform their life functions. Organisms, in nature, feed on one another for energy source. Some organisms are, however, capable of synthesizing their own food or energy source via a process called photosynthesis. This is the case of the phytoplankton in the question. These organisms are, therefore, called AUTOTROPHIC ORGANISMS or PRODUCERS.
On the other hand, some organisms are incapable of this self-production of energy source. Hence, they rely on other organisms for it. These category of organisms are called HETEROTROPHIC organisms, which is the category the large whale fall into due to its dependence on phytoplankton for energy source.
