After seeing a graph represented below, I have recognized the correct answer, and I think that the statement concerning the oxygen level in the lake which can be inferred from the graphs is being revealed by the option 1 -<span>Trout and whitefish require higher oxygen levels than do carp. As you can see the oxygen line on the graph shows that carp does not require as much oxygen as whitefish does require, as level is increasing on the left side.
Hope you will find it helpful!

Explanation:
Yes, the increase of algae could be related to Sarah farm due to her use of fertilizer.
Answer:
b) The two phenotypes are about equally adaptive under laboratory conditions.
Explanation:
According to the given information, the frequency of homozygous recessive genotype and the recessive allele is not changed over generations and is maintained at a constant level. A population maintains allele frequencies over generations without any changes when the environment is not changing and the existing allele frequencies are beneficial in terms of survival and reproductive success of the individuals.
In the given breeding program, both the recessive and dominant genotypes should impart beneficial adaptive traits to the organisms resulting in no change in their frequencies over several generations.
18. Enzymes bind with chemical reactants called substrates. In some reactions, a single-reactant substrate is broken down into multiple products.
20. stored evergy is released whenever these chemical bonds are broken in metabolic processes such as cellular respiration. Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP.
