Answer;

-ATP

Explanation;

Cellular respiration is the process by which plants and animals break down organic molecules such as glucose to obtain energy in the form of ATP, that is used to drive cellular activities such as transport and reproduction.

-The process takes place in three phases; glycolysis, kreb's cycle and the electron transport chain.

-Electron transport chain is the last stage of cellular respiration which builds up a surplus of hydrogen ions (protons) in the intermembrane space so that there will be a concentration gradient compared to the matrix of the mitochondria.  The concentration gradient is used to generate ATP (usable energy by the cell) through transfer of electrons.

The answer is <span>B. Water and ATP.

The main function of electron transport chain (ETC) is a production of ATP. It takes electrons freed in the previous stages of cellular respiration. It is actually a series of oxidation-reduction reactions in which the oxygen is the final acceptor of electrons. As the result, water and ATP are produced.</span>

Use this information to answer questions 6 - 11. Your original population of
grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6
