Answer:

50%

Explanation:

According to the given information, the woman is heterozygous for blue eyes. It means that the blue eye color is a dominant trait over brown eyes since heterozygous carrier genotypes are present for dominant alleles only.

Let's assume that the allele for blue eye color is "B" and the one for brown eye color is "b". Therefore, the genotype of heterozygous woman would be "Bb" and the genotype of the homozygous recessive male would be "bb".

A cross between Bb x bb gives following phenotype ratio = 50% brown eye : 50% blue eye

There is 50% probability of their child to have blue eye color.

Answer:

In order to propose a hypothesis, there is a need to first see the function of gills in fishes. The gills of fishes comprise blood vessels that exhibit inherited tendencies of getting oxygen out of the water, which was consumed by fishes from their mouths. These gills also comprise thin walls, and when water moves over these walls of blood vessels, the oxygen from water moves into the blood, and then this oxygen-enriched blood goes to various organs.  

Thus, one of the hypotheses in the given case, can be the number of blood vessels, which are found in the gills of the mentioned freshwater fish to be higher in comparison to the blood vessels found in the normal fishes, and apart from this, the surface area of the thin walls, which are found in the gills is also more in the new species of freshwater fish.

What are nodes, internodes, apical buds, & axillary buds?
xxMikexx [17]
Axillary buds are found at the insertion point of leaves and lateral branches in the nodes and give rise to lateral branches and flowers. Internodes are the stem regions between nodes. They lack lateral organs. It can be said that the stem is made up of nodes, internodes and axillary buds tidily arranged.
