What is the probability of producing a white rose when a red rose is crossed with a pink rose?
sammy [17]
A white rose cannot be produced in the G1 (first generation) of roses because the red rose will have a RR (R standing for red) allele combination. The pink rose will have a RW (R for red, W for white) <span>allele combination. When crossed all combinations will have at least one R allele, meaning that no roses (in the first generation) will have a WW allele combination. WW is the only allele combination that produces white roses.

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.

All of the following describe possible results of competition between two species except A) competitive exclusion. B) aposematic
boyakko [2]

Answer:

B) aposematic coloration

Explanation:

The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.
