What is true about the absorption and storage of fat-soluble versus water-soluble vitamins in the body?

rodikova [14]

The right answer is "<span>fat soluble are stored in the liver and fatty tissue ...".

Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat".These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.

"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>

Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique functions do you notice a

ASHA 777 [7]

Answer:

Microvilli is very common in these cells. They increase the absorption area.

Explanation:

Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.

The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. <u>Their principal function is to absorb</u>. The microvilli of the intestinal epithelium are very uniform in size and distribution.

ozzi

<h2>The correct answer is explained below:</h2>

Explanation:

According to the question, achondroplasia, a form of dwarfism, is caused by a mutant allele of the fibroblast growth factor receptor (FGFR) encoding gene.
This achondroplasia trait is dominant in nature. This is because presence of a single copy of the mutant allele results in the development of a dwarf phenotype.
Let the dominant mutant allele for the trait be represented by: A.
Let the recessive normal allele for the trait be represented by: a.
The individual with aa genotype is normal.
The individual with Aa genotype shows dwarfism.
The individual with AA genotype dies before birth.
As per the question, two people having achondroplasia have the genotype Aa.
Gametes produced by each of the individuals are, A and a.
Mating these individuals, we get the following possible offspring,

A a

A AA Aa

Phenotype Dies Dwarf

a Aa aa

Phenotype Dwarf Normal

The genotypes and the phenotypes of the possible offspring are represent in the Punnett square above.
The probability of the child to have achondroplasia is: $= \frac{2}{3}$ .
Since the child with AA genotype dies before birth so three (genotypes Aa and aa) out of four possible children survives.
