In which of the following ways is reproduction in plants similar to reproduction in animals?

a. plants and animals both go through conjugation when they reproduce.
b. plants and animals both can go through sexual reproduction.
c. plants and animals both produce eggs in ovaries and sperm in testes.
d. plants and animals both can gain genetic material by transduction.

b. Plants and animals both can go through sexual reproduction.

Explanation:

Sexual reproduction is a mode of reproduction wherein the fusion of male and female gametes produces zygote which in turn grows into an embryo. Both plants and animals can perform sexual reproduction. For instance, flowering plants produce male gametes in microsporangia and female gametes in megasporangia. The fusion of male and female gametes occurs in ovules. Animals produce male and female gametes in respective gonads. Humans produce sperms and egg cells in testes and ovaries respectively.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

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.
