Answer: Because they cannot be synthesized inside the body.

Explanation: The amino acid are the basis for the protein synthesis in the body. The protein regulates the various processes of the body.

There are two types of amino acids found in the body. One of them is essential amino acids as it cannot be synthesized inside the body and it must be taken by the food that we eat.

The other form of amino acids are non essential amino acids that are synthesized in the body itself and we need not to take it from the outer sources.

Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp
