<span>The answer would be: the regulation of biological cycles into regular, daily patterns

Circadian rhythm is not only related to the sleep pattern but also some of the other hormones that control the metabolisms like cortisol and melatonin. The rhythm also defines the body temperature fluctuation. The duration of the cycle should be around 24 hours which follow the duration of one day.</span>

What is the relationship between Microvilli of gut, epithelium, glucose, circulatory system, capillary fenestrations, glucose/AT

skad [1K]

The small intestine comprises of an external layer called epithelium, from which originates microvilli that are the extensions of the small intestine, which projects in the form of tubes and their prime activity is to give a large surface area of absorption to obtain the majority of nutrients.

The nutrients obtained by the microvilli are included into the circulatory system, the prime activity of the circulatory system is to carry different constituents like amino acids, glucose, proteins, and other complex components like oxygen and hormones. It also helps in the conduction of various metabolic wastes discharged from the tissues.

The circulatory system comprises many kinds of capillaries, the most essential of which are arterial capillaries, venous capillaries, and fenestrated capillaries. The fenestrated capillaries are characterized by the pores present in the endothelial cells, which permits small molecules and restricted concentrations of proteins to pass through.

The most essential nutrient carried during the whole process is glucose. It has been considered as the prime source of energy, which is further hydrolyzed to produce two molecules of ATP. The ATP is known as the energy currency of the cell as it provides energy for different cellular and metabolic procedures essential for life.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.
