42. Variation which exhibits a wide range from one extreme to the other is
A. phenotypic variation.
B. discontinuous variation.
C. continuous variation.
D. genotypic variation

C. continuous variation.

Explanation:

Variation within organisms refers to how different they are from another. In biology, variation can either be a continuous one or discontinuous.

A continuous variation is a type of variation in which there is a wide range of values from one phenotype/extreme to the other. In other words, there are a lot of values in between the extremes. For example, the human height can range from different degree of shortness to a different degree of tallness. Hence, human height is an example of a trait that exhibit continuous variation.

Therefore, a variation which exhibits a wide range from one extreme to the other is CONTINUOS VARIATION.

hello which   of the following there is nothing!

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
