Why are amoebas more likely to use endocytosis than red algae?

This is because amoeba cannot make their own food but algae can.

Explanation:

Endocytosis is the method by which the amoeba engulf food by their podocytes also known as pseudo feet.

Red algae is capable of performing photosynthesis. It can trap sunlight and perform and synthesize food which can be used as a source of energy.

This is the reason why amoeba use endocytosis and algae perform photosynthesis.

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

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.
