Lemur [1.5K]3 years ago
6 0

Answer:

Recent studies have shown that dark skin colour was developed in the past for protection against cancer. Scientists claim that in the past natural selection favoured humans having dark colour as compared to humans having a fair colour. This is because humans having a darker colour produced more melanin which protected them from ultraviolet radiation. As a result, this skin colour protected more against skin cancer. Hence, Having a darker skin colour protected in survival and reproduction to people thousands of years ago.

The data shows that recently the shark population has increased. How will the increase in the shark population affect the other
e-lub [12.9K]

Answer:

There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).

Explanation:

This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.

However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.

What is one way the immune system reacts when a virus enters the body?
Gennadij [26K]

Answer:

As the body tries to fight the infection, the immune system causes inflammation to make it hard for the virus to copy itself. The process of fighting the infection causes most of the symptoms people have. As the virus makes its way down to the lungs it can cause the lungs to become inflamed. This can lead to pneumonia.

Check all statements below that are true
victus00 [196]

Answer:

Statements thar are true:

Some  organisms have phenotypes that make them better  increase chances of reproduction.

Natural selection continues to occur even today

Phenotypes found In the most successful members of a species become the most prevalent after  several generations.

Explanation:

It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.

Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.

Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.

A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.
