an amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. when an amoeba feeds, it first makes contact with the food particle. next, the amoeba starts to surround the particle. once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. the ph in the vesicle is then lowered and the contents are degraded.

what type of transport is involved in this process?
a. endocytosis
b. passive transport
c. diffusion
d. exocytosis

Here is your answer

A. endocytosis

Reason :

Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of plasma membrane, which then buds off inside the cell to form a vesicle containing the ingested material. Endocytosis includes pinocytosis(cell drinking) and phagocytosis(cell eating).

HOPE IT IS USEFUL

The correct answer is option A- endocytosis.

Explanation:

The process of engulfing foreign material from the surrounding environment is known as phagocytosis. Phagocytosis is also known as cell eating as it eats or engulfs the foreign material which is a part of a larger process called "endocytosis".

Endocytosis is a process of engulfing of macromolecules and non-functional cells. It takes place due to the invagination of the plasma membrane which surrounds the particle which is released into the cytoplasm.

Thus, option A- endocytosis is the correct answer.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
