The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.
<h3>What is Natural selection?</h3>
Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.
Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.
Therefore, the correct option is D.

Explanation:
Answer:
1.875 is the expected number of children the couple will have.
Explanation:
<em>The probability of an event </em><em>X</em><em> is denoted by </em><em>P(X)</em><em>.</em>
Let assume that X is the number of children to whom the couple will give birth. The couple can have at most <em>four children</em> with the following probabilities.
- The couple will have one child if the first is boy, thus:
For one child P(X)=1/2=0.50
- The couple will have two children if the first is girl and the second is a boy, thus:
For two children P(X)=0.5×0.5=0.25
- The couple will have three children if the first two are girls and the third is a boy, thus:
For three children P(X)= 0.5×0.5×0.5=0.125
- The couple will have four children if the first three are girls and the fourth is a boy, or if all the four are girls. thus:
For four children P(X) =(0.5×0.5×0.5×0.5)+(0.5×0.5×0.5×0.5)=0.125
<u>Now calculating the expected number of children the couple will have:</u>
NOTE: Formula is given in the attached pic
Expected number of children = E(X)= (1×0.50)+(2×0.25)+(3×0.125)+(4×0.125)
E(X)= 1.875
Science refers to the construction of knowledge by using the scientific method. This method is based on empirical evidence.
Science can be defined as the construction of knowledge (scientific knowledge) by using the scientific method.
The scientific method includes several sequential steps:
- Observation
- Ask questions
- Form a testable explanation (hypothesis)
- Test the hypothesis
- Collect results (empirical evidence)
- Draw conclusions
In the scientific method, empirical evidence can be used to support the working hypothesis.
