Answer:
It is expected that 25% of the offspring are silver blue.
Explanation:
As was shown in the question above, in a population, the brown color is dominant, while the silver blue color is recessive. Thus, the brown color can be observed in dominant homozygous (AA) or heterozygous (Aa) organisms, since the dominant allele inhibits the expression of the recessive allele. However, the silvery blue color is only observed in homozygous recessive organisms (aa), since the recessive allele is only expressed in the presence of another recessive allele.
In the figure attached below, we can see that if a heterozygous brown organism (Aa) crosses with a silvery blue individual (aa), the offspring will be composed of 50% brown individuals (Aa) and 50% silvery blue individuals.
Answer:
Saliva contain enzymes.
Explanation:
In the mouth, when chewing a bite of bread, it mixes with the saliva in the mouth which is secreted by the salivary gland. The food is broken down by chewing which is converted into Bolus through the saliva. The saliva comprises of digestive salivary amylase which help to digest carbohydrates and breakdown carbohydrates into smaller pieces.
Bread is a carbohydrate, digestive salivary amylase breakdown bread into sugars.
Therefore, digestion begin from the mouth and it contain saliva which comprises of the enzymes.
Answer:
8 chromosomes in each daughter cell
Explanation:
Mitosis creates identical cells. If there are 8 chromosomes in the parent cell, there will be 8 chromosomes in each daughter cell. The way it works is that in late Interphase, the number of chromosomes and DNA double. In this case there would be 16 chromosomes. And when the cell splits into two during cytokinesis, each of the two would get half the chromosomes. Hence, there would be 8 chromosomes in each daughter cell.
