Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.
A scientist who classified organisms is called a Taxonomist.
The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.
Answer:
Follows are the solution to this question:
Explanation:
The following are the two considerations demonstrating that there would be less biodiversity than the tropical areas in the Mediterranean climate as well as polar areas.
- The first reason is all tropical areas experience drastic temperature variation.
- The second reason is early in the earth's history, the northern latitudes are inhabited.
Facilitated diffusion of substances crossing the cell (plasma) membrane takes place with the help of proteins such as channel proteins and carrier proteins.
