Continued selection tends to favor: a. both extremes simultaneously in the variation of the trait b. one of the extremes in variation c. the average or mean value for the population d. none of these

option A: both extremes simultaneously in the variation of the trait

Explanation:

The continuous selection is controlled by the expression of many genes (polygenic inheritance). The environment play a key role in continuous selection. In this type of selection two extreme variations becomes common and the organisms of intermediate state are lost. Thus, continued selection tends to favor both extremes simultaneously in the variation of the trait.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
