Answer:

They are in equilibrium

Explanation:

The carrying capacity of a population is the maximum number of individuals a population can cater for or handle at a specific time, often limited by the available resources.

A population that has reached its carrying capacity has a population size that oscillates a little above or below the maximum the environment can support.

<em>Hence, if the birthrate and the death rate of the bison population that has reached its carrying capacity are equal to each other, the rate of immigration and emigration will be at equilibrium with each other.</em>

Answer:

A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."

D. The rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.

Explanation:

It is important to consider that Kenny hikes all day but at a steady pace, whereas Janelle runs very fast. So Kenny's case, the supply of oxygen is sufficient to maintain aerobic respiration within the muscle cells. During this process only CO2, Water, and ATP are produced; therefore, there is no oxygen debt. We should keep in mind that the body shifts to anaerobic metabolism only when the supply of oxygen is limited.

In Janelle's case, running fast would need energy at higher rates and the supply of oxygen would not be sufficient to generate a high amount of ATPs. Therefore, to compensate for this deficiency, cells will start fermenting glucose to lactic acid and produce ATP and maintain energy demands. This lactic acid causes fatigue and this is why Janelle has aching and breathing hard. Breathing hard is also automatic reflux to inhale more oxygen and meet oxygen demands but even breathing hard would not be able to make it and the body will shift to anaerobic respiration automatically.

3. During meiosis,
Anna71 [15]

Answer:

Cells divide twice

Explanation:

Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells  have half number of chromosomes.

Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.

Thus, the correct answer is option (4).
