Meat is not a good source of protein because it does not provide the body with all the essential amino acids.a. True
b. False

Answers

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

. All BUT ONE statement describes an advantage of meiosis.. A). Variation is aided by crossing-over which occurs during meiosis.. B). Meiosis ensures daughter cells receive one of each kind of gene and half the chromosome number.. C). Independent assortment provides a huge number of possible genetic combinations in daughter cells.. D). Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms.

Answers

Answer:

All statements except "D). Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms" describe the advantages of meiosis.

In multicellular organisms, growth and repair of the tissues are achieved by mitosis.

Mitosis is the process in which parent cell divides into two daughter cells each with the same and an equal number of chromosomes as present in the parent cell.

It helps in producing new cells and replacing the old or damaged cells.

It generally takes place in all the cells of the body (somatic cells) except germ cells.
