Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>

Answer:
(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Explanation:
As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.
Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.
This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.
