Answer:
...cells switch to an emergency mode in which the body uses anaerobic metabolism during exercise to provide the necessary fuel for the muscles.
Explanation:
Anaerobic metabolism is the generation of energy by burning carbohydrates in the absence of oxygen. This happens when the lungs cannot place enough oxygen in the bloodstream to meet the energy demands of the muscles. It is used only for short periods of activity.
When there is not enough oxygen in the bloodstream, glucose and glycogen cannot be broken down into carbon dioxide and water. Instead, lactic acid is produced, which can accumulate in the muscles and degrade muscle function.
Answer:
The frequency of the recessive allele which codes for grey pelt character will rise above 20%, while the that of the dominant allele that confers brown pelt character will decrease below 80%.
Explanation:
Since the population of foxes with brown pelts are being selectively hunted by humans, the population of foxes with brown pelts will keep reducing while the population of foxes with grey pelt will thrive in its place.
<em>Hence, the the frequency of the recessive allele which confers grey pelt attribute will rise above original 20% within the population, while the dominant allele will decrease below 80%.</em>
6. Algae are biotic factors. They are living organisms which have the capability to produce food through photosynthesis. It acts as a producer. Also they appear on the wall of tank through reproduction , which is characteristics of living being.
7. Snail is also a biotic factor like algae. They are classified as consumers. They feed on algae to survive with in the tank. They move while feeding on algae and movement is an important trait of living being.
8. Light Bulb is an abiotic factor. Though it is an essential requirement for fish to survive but since it is not a living being , it is considered as abiotic. While fish on the other hand is a biotic factor as it possess life in it.
