A population of snails on an island is disrupted during a violent storm. Portions of the population are carried by the storm surge to two new islands, while a portion remains on the original island, creating three separate populations. Conditions on one of the new islands are exactly like conditions on the original island. However, snails that landed on the second new island encounter a voracious new predator. What is likely to happen to these three populations? A.
Speciation will occur at the same rate in all three snail populations.

B.
Speciation will occur at the same rate in the snails that landed on new islands but not in the original snail population.

C.
Speciation will rapidly occur in one of the snail populations that landed on new islands but not in the other two snail populations.

D. Speciation will occur in the original snail population but will not occur in the populations that landed on new islands.

C

Explanation:

The correct answer would be that speciation will rapidly occur in one of the snail populations that landed on new islands but not in the other two snail populations.

Speciation generally means the evolution of new species. Two populations of the same species that become separated into different environments will evolve differently as a result of different environmental conditions. Each population might then become new species as they continuously try to adapt to their environments.

In the case of the 3 populations of snail in which 2 live in similar environmental conditions while the remaining one experiences a voracious new predator, the latter will evolve more rapidly in order to survive the effects of the predation, and as such, speciation will occur more rapidly when compared to the two remaining populations.

The correct option is C.

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!
