describe convection currents. draw a picture to describe it within earth's interior.

I can't draw pictures in , but you can look up images on Google or other search engines to find many useful diagram. Just search mantle convection.

Now I'll explain how it works.

Heat is transferred from the Earth's core which heats the magma above it, and this (comparatively) hot magma rises to the top, much like how hot air rises, and then since it is further away from Earth's core than it was when it was first heated, it cools, and falls back down to the bottom, much like how cold air moves down in the atmosphere, and now more hot magma moves to the top after being heated, cools, and the cycle continues.

Hope that helps. Let me know if I need to elaborate or explain something else.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

i believe the answer would be b. hope it : )
