Answer:

2) 25%

Explanation:

Let the traits for the black coat color be = BB

Let the traits for the brown coat color be = bb

Let the traits for heterozygous black coat color be = Bb

Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.

This implies that if two rabbits that are both heterozygous for black coat color cross together;

i.e  Bb × Bb ;

The offspring will be (BB, Bb, Bb, bb)

BB (rabbits with black coat color) = 1/4

Bb (rabbits that are heterozygous for black coat color) = 2/4

bb (rabbit with brown coat color) = 1/4

Lets focus on ''bb'' ;

bb = 1/4 × 100%

= 25%

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. de
Pie

Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
