Ahmed makes a venn diagram to compare active transport and passive transport across the cell membrane. which label belongs in the region marked x?
uses energy to work
moves from high concentration to low concentration
moves across the cell membrane
is a form of diffusion

You did not provide the Venn Diagram but maybe this would help you out.

There are ways molecules move in and out of the cell membrane and they can be categorized as Passive or Active transport.

Here are some descriptions of passive transport, active transport, and both.

Active Transport                 Both                        Passive Transport

-Uses energy                 -Moves across            - form of diffusion

-Moves from low            cell membrane         -   Moves from high

to high concentration                                   to low concentration

Hopefully, this will help you fill in your Venn Diagram

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
