Answer:
<em> The carrying capacity is determined only by the density-dependent factors.</em>
Explanation:
The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.
Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
Answer:
The correct answer is - option 2, 3, and option 5.
Explanation:
Biological evolution is the change in genetic level of an individual population that is developed or inherit over a period of time and several generations. Changes can be minute, large, can be identified or not noticeable.
In the given question some of the examples of biological evolution are given such as O genotype individuals increases due to the reduction in population size in the small human population, similarly, one species diverged into two different species on the basis of the adaption they developed in island. Sickle cell anemia frequency is also is an important example of the as it decreases over time.
Thus, the correct answer is - option 2, 3, and option 5.
