Answer:
The correct answer is option A. storage of bile.
Explanation:
The liver is the organ that is present on the right side of the abdomen and is almost the size of a football. Liver provides a different role in the body but major function of the liver is to detoxification of blood coming from the digestive tract. It produces different proteins and helpful in metabolizing all three major macromolecules that are protein, carbohydrate, and fat. The liver also produces the bile that is helpful in digestion.
Bile that produces and moves from the liver through bile ducts and stored in the gall bladder concentrated and secreted during or after food intake to assist the digestion process.
Thus, the correct answer is option A. storage of bile.
The amount of water on the planet is fixed; it neither increases or decreases. Glaciers are sheets of moving ice. This water to form these extensive sheets must come from somewhere. The water comes from the most extensive store on the planet; the oceans. Ice Ages always corresponds to periods of low sea level because much of the ocean water is is land locked as glaciers.
Answer:
Read the explanation section.
Explanation:
We know, sand can't contain water because of it's nature. But mud can contain water. For preservation of an organisms, sometimes water is needed because many microbes needs water which helps to preserve the organisms. Along with this, mud has the nature of holding things for long time inside of it but sands doesn't have this.
As sand can't store water so that microbes don't do their work properly and that's why preservation get hampered.
But in mud, this problem isn't present.
Explanation:
The problem says that the hairless phenotype never breeds true. That means that it's not the result of a homozygous genotype (H₁H₁ or H₂H₂), so it is caused by the heterozygous genotype (H₁H₂).
The <u>expected </u>offspring from the cross between two Mexican hairless would be:
<h3>P
H₁H₂ x
H₁H₂</h3><h3>F1 1/4
H₁H₁, 2/4
H₁H₂ and 1/4
H₂H₂.</h3>
And the <u>expected</u> phenotypic ratio 3:1. However, the observed offspring shows a 2:1 ratio. What's happening?
If the observed phenotypic ratio in the offspring of a monohybrid cross (a single gene with two alleles) is 2:1, we can suspect that one of the genotypes is lethal in homozygosis and therefore does not appear in the progeny (the puppies are born dead).
If we proposed that the H₂ allele is lethal in homozygosis, then:
- The H₁H₁ genotype would cause normal puppies --> 1
- The H₁H₂ genotype would cause hairless puppies --> 2
- The H₂H₂ is lethal and causes the death of puppies --> 0
The phenotypic ratios change to 2:1, as observed in the experiment.
<span>Tadpoles don't havel egs, just small tales. They are basically a very small undeveloped frog, like a human foetus is completely undeveloped. It has to also stay in water. Frogs on the other hand have legs and are differently colored and can reproduce. They are adult, fully developed versions of tadpoles.</span>
