In the lizard species l. vivipara, most females from the colder, mountainous part of the range live much longer than do individuals from warmer, lowland regions. compared to the lowlands, what life-history trait is expected in lizards living in the mountains?
a. equivalent fecundity
b. increased fecundity
c. decreased fecundity

C Decreased fecundity

Explanation:

Decreased fecundity.

Fecundity is nothing but the ability to reproduce.

Lizards living in colder climates cannot reach the body size required for reproduction. As a result, they invest available energy to increase the body size as a result of which, they enter reproduction later.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

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.
