Which of the following statements regarding Kimura's Neutral Theory is FALSE/INCORRECT? Choices:
A:Neutral mutations can be either beneficial or deleterious

B: Mutations occur by chance

C: Many mutations are not acted upon by selection

D: All of these statements are true/correct; there are no false statements

E: All of these statements are false/incorrect

F: Neutral mutations can be influenced by genetic drift

G: Many mutations are selectively neutral

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
