Answer:
50%
Explanation:
This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.
According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).
Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.
Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.
<span>Organic materials found in soil such as dead plants, animal fesis, bacteria, and fungi cause decomposition in the soil or a decaying breakdown of organic materials which is needed for proper soil health. Decomposition releases small particles of microorganisms or detritus which other living organisms feed on and release energy as well as recycles inorganic materials back into the food chain. These small particles are so small that the naked eye cannot see. The process of photosynthesis is very important for the food chain. Healthy soil helps plants grow, decomposition feeds the plants, the sun provides energy which releases carbon dioxide so the plants can grow, and the plants release oxegen into the atmosphere which living organisms need to survive.</span>
