Vitamin <u>A</u> is necessary for vision, bone growth, and maintenance of epithelial cells.
We can define vitamins as micronutrients that perform various important functions in the body. Vitamins cannot be synthesized by the body of a person and hence are derived from the diet of a person.
Vitamin A is present in many foods and it is a fat-soluble vitamin. Vitamin A helps the body in various functions such as improving vision, helping the immune system, growth of bones, maintenance of cells etc.
Certain foods contain carotenoids in them. A person's body has the ability to convert these carotenoids into Vitamin A which is then used by the body for various functions. Some preformed sources of Vitamin A include dairy products and eggs.

Nowadays we have much more modernized farming. There are combines, tractors and other machines. Back then they used hundreds of workers and now 1 machine gets all that done in half the time. Try googling it for more info.
Answer:
Lysosomes.
Explanation:
HEXA (Hexosaminidase A) is the functional enzyme and encoded by the HEXA gene. The main function of this enzyme is the hydroxylation of the gangliosides.
The mutation in this gene leads to the lysosomal storage disease. The GM2 starts accumulating in the lysosomes and causes Tay Sach's disease. This is a genetic disorder that leads to the breakdown of the cells of the spinal cord and the brain.
Thus, the answer is lysosomes.

Answer:
NAD is a coenzyme found in all cells. It consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and another that contains nicotinamide.
Explanation:
In metabolism, NAD participates in oxidation reduction reactions. This coenzyme is found in two forms in the cells: NAD and NADH. NAD accepts electrons from other molecules and is reduced, forming NADH, which you can use as a reducing agent to donate electrons. These electron transfer reactions are the main function of the NAD.
In living organisms, NAD can be synthesized from scratch from the amino acids tryptophan or aspartic acid. Some NADs are found in nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry is similar to NAD, although it has different functions in metabolism.
