A child holds a red ball. Why does the ball look red?
Tasya [4]

Answer:

D) All visible light waves except red are absorbed by the ball

Explanation:

When we see things that are a certain color, it is because the object is absorbing all the visible light waves except the one we are seeing. In this case, the ball is absorbing every color on the visible spectrum except for red. Red is being reflected back towards the child's eye which is why the child sees the ball as red.

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
GuDViN [60]

Answer:

2. A change occurs in the environment.

4. Poorly adapted individuals have decreased survivorship.

1. Well-adapted individuals leave more offspring than do poorly adapted individuals.

3. Genetic frequencies within the population change.

Explanation:

The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.

Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.

Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.

Hence, the sequence of events is 2, 4, 1 and 3.
