Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
I think this is actually a physics question-
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.
Hope this helps :)
Non-enveloped viruses most commonly gain access to host cells through some form of endocytosis, such as phagocytosis, in which the host cell engulfs the virus with its cell membrane, bringing it into the cell.
Answer:
Genetic drift
Explanation:
This can be explained as a continuous in reduction in allelic frequencies over a short period of time leading to loss of alleles. Loss of alleles can allow for fixation of one allele over a short period of time. When allelic frequencies continue to drift up and down over a short period of time, thing could promote loss of alleles

The axial skeleton supports the central axis of the body, the apendicular skeleton supports the limbs
