Aspecies that has experienced a severe bottleneck event would be expected to
a.
be better able to adapt to changing environmental pressures
b.
have few instances of inbreeding
c.
be more susceptible to disease and famine
d.
retain significant genetic diversity

c. be more susceptible to disease and famine.

Explanation:

A population bottleneck is an event that reduces the size of a population in a drastic way. This can be caused by many different events, such as environmental disaster, hunting or habitat destruction. One of the consequences of such an event is the fact that these species lose many of the gene variants that were present in the original population. This low level of genetic diversity in the surviving population makes it more susceptible to disease and famine.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
