The vitamin that plays an important roles in the epithelia and in the synthesis of visual pigments is vitamin A.
Vitamin A (retinol) is needed for the synthesis of photopigments. The photopigment rhodopsin is synthesized withinside the rods and is answerable for imaginative and prescient beneathneath low ranges of light. When nutritional reassets of diet A are insufficient for a protracted length of time, the quantity of visible pigment withinside the photoreceptors declines.
Vitamin A (VitA) is a micronutrient this is important for preserving imaginative and prescient, selling boom and development, and defensive epithelium and mucus integrity withinside the body.Vitamin A is critical for lots physiological processes, which includes preserving the integrity and feature of all floor tissues (epithelia): for example, the skin, the liner of the respiration tract, the gut, the bladder, the internal ear and the eye.

In F2 Generation;
Genotype
There are 25% TT (homozygous dominant, tall plants).
50% Tt (heterozygous tall plants), and
25% tt (homozygous recessive dwarf plants).
This is how dwarf characteristics reappear in the second generation.
The Phenotype of F2 generation is 3:1 (Tall : Dwarf)
I have attached a document to this answer to facilitate effective understanding if there is anormalities in arrangement the Punnet Square.
Photosynthesis in algae cells
Ecosystems were able to maintain themselves by cycling the
nutrients and energy obtained from external sources. The flow of energy through
a food chain is known as energy flow. At tropical level, solar energy is used by the primary producers to produce organic plants materials through photosynthesis.
