Why does uncontrolled growth of algae in a lake cause fish to die?
Responses

The algae compete for the same food source as the fish.

Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems?
Responses

Burnt ground encourages the growth of grasses, which compete with shrubs for nutrients.

If the father is color-blind, it means he carries the allele for color blindness on his X chromosome. If the mother does not carry the allele, it means she has two normal X chromosomes.

In this scenario, there is a 50% chance that a male child will inherit the color blindness allele from the father. This is because males inherit their X chromosome from their mother, and if the mother does not carry the color blindness allele, the male child will only receive a normal X chromosome.

Therefore, the probability of a male child being color blind in this case is 50%.
