The graph below is an age structure diagram for a population of africa elephants

according to the diagram in which age classes do females out number males

Option A)  C, E and F

Explanation:

It is very clear from the graph, that females will outnumber males in the particular age category where the orange occupies a greater number.

Therefore through observation, we can see that the orange color which denotes females is greater than blue color which denotes males in the following age categories-

Category C- 20-24.9 years of age,

Category E- 35-49.9 years of age   and

Category F- >50 years of age.

Hence, C, E and F only.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
