Which ones are false and which are true

i know the answer for question 8 & 9

8) Volume is the amount of space a 3D shape takes up.

A cubic cm block takes up 1 cubic cm. This is written as 1 cm³.

You can work out the volume of a shape by multiplying height × width × depth.

If the shape is made of cubic cm blocks, you can count the cubes to find the shape's volume.

9) The face or surface of a solid on its sides. That is, any face or surface that is not a base. See also. Lateral surface area, prism, pyramid, cone, cylinder.

- i hope this helps

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
