Answer: Apply Hardy-Weinberg Equilibrium equation

Explanation:

Assuming the known parameters are the

frequency of two alleles 'B'and 'b' in a certain plant species, where 'B' is 0.19 and 'b' is 0.81

To calculate the percentage of heterozygous individuals in the population.

Apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.

Therefore, the number of heterozygous individuals (Bb) is equal to 2pq

2 × 0.19 × 0.81 = 0.31 or 31%

(b) To calculate the percentage of homozygous recessives in the population.

The homozygous recessive individuals (bb) are represented by the q^2 term in the H-W equilibrium

0.81 × 0.81 = 0.66 or 66%

What is one function of the organ system shown below in the picture?

slamgirl [31]

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

How does deforestation affect the water cycle? A. It increases the amount of percolation. B. It increases the amount of transpir

netineya [11]

The best option for this question is: '<span>It increases the amount of runoff</span>'. Plant life acts as a barrier to the overland flow of water, thereby slowing the flow and allowing increased infiltration of water into the soil. Deforestation and overgrazing are major contributors to erosion, as plants act to bind the soil, and their removal allows the combination of looser soil and increased runoff to move masses of sediment into rivers and lakes. Deforestation will in fact decrease transpiration and percolation and precipitation rather than increase them.

You have found a new prokaryote. What line of evidence would support your hypothesis that the organism is a cyanobacterium? You

ella [17]

Answer:

It is able to produce oxygen

Explanation:

The line of evidence that would support my claim is that the observed prokaryotes can produce oxygen. The cyanobacteria or the blue green algae are the only know prokaryotes that utilises photosynthesis which leads to the release of oxygen. Since it has already been established the discovered organisms is a prokaryote, it can then be confirmed that since this organism can produce oxygen, it is a cyanobacteria and that it also has features peculiar to the cyanobacteria
