Which limitation of fuel cells is the most likely reason why people are concerned about using fuel cells in cars?
a. hydrogen gas is volatile.
b. water contains a lot of hydrogen atoms.
c. fuel cell cars cannot drive at extreme speeds.
d. fuel cell cars are very quiet.

Hydrogen gas is volatile.

Explanation: The limitation of the fuel cell for which the people are concerned is that hydrogen gas is volatile and the cars at high speed might crash.

This property of the fuel cell is a limitation because hydrogen is volatile at room temperature and can be made non volatile at lower temperatures which is not possible when it is used as a fuel.

So, it is a limitation of the fuel cells to be used in cars.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

climate change and pollution
