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.

Answer:

Explanation:

There are at present 20 major amino acids produced in the body. These amino acids are important biological components in the body. They are the building blocks of proteins. Also essential in the synthesis of nucleotides including the DNA and RNA. There are different ways of classified these amino acids:

Essential and non essential. The essential amino acids cannot be synthesized from scratch in the body but has to be obtained from our diet, while non essential is produced by the body

Acidic, basic, neutral, polar, non polar etc.

The essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

While the non essential amino acids are: alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

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.

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.

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:

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.

Answer:

the concentration of misfolded proteins would be higher than normal.  

Explanation:

Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.

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.

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.

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.

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.
