Answer:

1. Mouth

4. Stomach

Explanation:

The mouth and the stomach are both sites of mechanical and chemical digestion of food.

Digestion in the Mouth:

In the mouth, the teeth grind and mash the food into smaller pieces that aid in proper digestion.
Saliva produced in the mouth contains the carbohydrate digesting enzyme, salivary amylase.

Digestion in the Stomach:

In the stomach, protein is mainly digested by the combined action of low pH, protease enzymes like pepsin and the contraction of the muscles of the stomach.
Pepsin breaks down protein in the presence of stomach acids.
The muscles of the stomach contract and relax and aid in mixing the enzymes and acid together, consequently, aiding in digestion.

Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp
