A marine scientist observes that dissolved oxygen decreases with increasing ocean depth. He concludes that deep sea creatures mu
Dimas [21]

Answer: B.) More research is needed to reach a conclusion, including related variables

Explanation:

As it is evident that oxygen is necessary element for living beings. It is required for the process of respiration, in which the food particles are broken down in the presence of oxygen into simpler substances.

Applying this knowledge to the given study suggests that all organisms require oxygen which can be less or more depending upon their habitat either in the shallow waters or in the depths. This conclusion is invalid and requires more explanatory approach which can be achieved by more research so as to derive a valid conclusion in which the two variables oxygen and relative habitats can be compared.

100 individuals whose genetic makeup is composed of 20% recessive alleles join an established population. The established popula
NeX [460]

Answer:

population = 600

heterozygotes = 2pq

The homozygous recessive percentage = q^{2}

q = 0.1

Solve for q:

∴ q = \sqrt{q}

∴ q = \sqrt{0.10}

∴ q = 0.316

solve for p:

for p + q = 1,

thus p = 1 – q = 1 – 0.316 = 0.684  

The heterozygotes = 2pq

2pq =  2 x 0.316 x 0.684 = 0.432

600 x 0.432 = 259.2  = 259

so,  the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.

Hence, the correct answer is 259 .
