Answer:
Zebra mussels feed on phytoplankton, which zooplankton need as a food source.
Explanation:
The population of zooplankton in Lake Erie and the Hudson River declined due to the arrival of zebra mussels because Zebra mussels feed on phytoplankton, which is the main source food of zooplankton. So due to limited or scarcity of food in the environment, the zooplankton die due to hunger that leads to the decrease of population of zooplankton in that environment.
Earth's atmosphere is composed of air. Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.

Answer:
p = 0.34
Explanation:
The green allele is recessive, meaning two copies of q (qq) are required to be green. Conversely, animals that are either pp or pq will be blue.
If 44 organisms are green, that means 44 are qq.
For genotype frequencies, the equation is:
homozygous dominant genotype + heterozygous + homozygous recessive = 100%
Which is denoted as
p² + 2pq + q² = 1
We know that q² = 44/100 = 0.44
To work out q, we can do
= 0.66
For allele frequencies, the total must add up to 100%, so
p + q =1
We know that q= 0.66
So p = 0.34, because 0.66 + 0.34 = 1
Answer;
Homozygotes increase in frequency in the population over generations. and genetic variation decreases in the section of the population.
Explanation;
-Inbreeding is the mating of relatives or, mating of individuals with at least one common ancestor. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes.
-By inbreeding, individuals are further decreasing genetic variation by increasing homozygosity in the genomes of their offspring.
