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.Over 95% of incoming UV-B radiation is absorbed in the stratosphere. Please select the best answer from the choices provided
Answer:
True
Explanation:
The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.
The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat.
This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.

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.

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.

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:
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.

I neeed help pls answe them plssss
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.

Answer:
Asexual reproduction in animals occur through fission, budding,e.t.c.
Sexual reproduction starts with the combination of a sperm and egg which is called FERTILISATION.
Explanation:
The reproductive parts in animals produce gametes that fuse and form ZYGOTE.
Okay, hope it helps.
Answer:
[tex]\boxed{\mathrm{view \: explanation}}[/tex]
Explanation:
Animals should be matured to reproduce.
The animals can reproduce sexually, that involves fusion of sperm and ova inside the body.
Few animals can also reproduce asexually, asexual reproduction does not involve the fusion of gametes, the genetic material is combined to produce an offspring that has inherited the genes of the parent.
Is Natural law theory is inconsistent with a theory of human rights. True / False
Answer:
i think that it's false.
Explanation:
Natural law is a theory in ethics and philosophy that says that human beings possess intrinsic values that govern our reasoning and behaviour. Natural law maintains that these rules of right and wrong are inherent in people and are not created by society or court judges.
The Interests Theory Approach. Advocates of the interests theory approach argue that the principal function of human rights is to protect and promote certain essential human interests. Securing human beings' essential interests is the principal ground upon which human rights may be morally justified.
In jimsonweed, purple flower (P) is dominant to white (p), and spiny pods (S) are dominant to smooth (s).
A true-breeding plant with white flowers and spiny pods is crossed to a true-breeding plant with purple flowers and smooth pods. Determine the phenotype of:__________.
a) the F1 generation;
b) the F2 generation;
c) the progeny of a cross of the F1 plants back to the white, spiny parent; and
d) the progeny of a cross of the F1 back to the purple, smooth parent.
Answer:
See attached image for detailed punnet squares and diagrams
a) F1 generation: Purple flower and spiny pods (PpSs) offsprings
b) F2 generation: Puple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, spiny pods (3), white flower, smooth pods (1).
c) The progenies are: PpSS (4), PpSs (4), ppSS (4), and ppSs (4)
d) The progenies are: PPSs (4), PPss (4), PpSs (4), Ppss (4)
Explanation:
This question involves two distinct genes in jimsonweed; one coding for flower colour and the other for pod texture. The alleles for purple colour (P) and spiny pods (S) are dominant over the alleles of white flower (p) and smooth pods (s) in the two genes respectively.
A true-breeding plant with white flowers and spiny pods will have genotype: ppSS while a true-breeding plant with purple flowers and smooth pods will have genotype: PPss. In a cross between these two parents, the following combinations of gametes will be produced:
ppSS- pS, pS, pS and pS
PPss- Ps, Ps, Ps, PS
a) Hence, the F1 offsprings from this cross will possess a heterozygous genotype: PpSs, which is phenotypically purple-flowered and spiny-pod.
b) if the F1 offsprings are self-crossed i.e. PpSs × PpSs, gametes PS, Ps, pS, ps will be produced by each parent. These gametes will be used in a punnet square (see attached image) to produce the following F2 offsprings in proportion:
Purple flower, spinny pods (9)
Purple flower, smooth pods (3)
White flower, spiny pods (3)
White flower, smooth pods (1)
c) if the F1 offsprings are crossed back with the white, spiny parent i.e. PpSs × ppSS. The following progeny of offsprings will be produced: (see attached image)
PpSS (4),
PpSs (4),
ppSS (4), and
ppSs (4)
d) if the F1 offsprings are crossed back with the purple, smooth parent i.e. PpSs × PPss, the following progeny will be produced:
PPSs (4),
PPss (4),
PpSs (4), and
Ppss (4)
The true breeding plant.
As per the question, the jimson weed is a purple flower with capital P and is dominant to white (p) and a spiny pods of (S) which are dominant to smooth (s). The Punnett square method is used for the method. The true breeding have seperate types of genetic make ups.
Answer is F1 generation (PpSs), F2 generation has 9 purple flowers.
True-breeder plant with the white flowers and spiny pods s crossed to a true-breeding plant with the F1 gene will be a flower and spiny pods (Pp Ss) offspring. For the F2 gene Purple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, and spiny pods (3), the white flower, and a smooth pods (1).The progenies are of PpSS (4), PpSs (4), pp SS (4), and ppSs. The progenies follow PPSs (4), the PP ss (4), PpSs (4), Ppss.Learn more about the purple flower.

) 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.

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.

What type of transport occurs in the cell membrane when a person does sports and is consuming alcohol?
Cellular transport: it is the exchange of substances through the plasma membrane, which is a semipermeable membrane. Transport routes are through the cell membrane
It allows the metabolism waste to be expelled from its interior It allows the movement of substances that it synthesizes as hormones. Metabolic energy: is the way in which it acquires nutrients through processes of incorporation into the cell of nutrients dissolved in water.
Therefore, when the person consumes alcohol in excess the ce transport is part of the disincorporation of toxic waste, while when the person does sports, and is supposed to have a balanced diet, the cellular transport uses it for his metabolic energy.
