Answer:
The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining <u>adaptation and speciation.</u> There was five observation of the theory of natural selection.
1) The population produces more offspring than there are adults, in each generation.
2) The population does not continue to grow in size.
3) Food and many other resources are limited.
These three observations interfere that individuals compete for resources within a population.
4) Individuals within all populations vary.
5) Many variations are heritable.
He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.
These observations and interpretations helped him to propose the theory of natural selection. The theory tells the <u>heritable characteristics in a population change over time</u> <u>become more adapted in generation after generations.</u>
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
Hello,
concentration gradient<span> is the process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are typically separated by a membrane.
correct me if i'm wrong!
But since concentration gradient is the process of particles, then </span><span>Sedimentation is the tendency for </span>particles<span> in suspension to settle out of the fluid in which they settle as individual </span>particles<span> and do </span>not<span> flocculate</span><span>
