Membranes will allow and inhibit certain ions/molecules. I don't believe it can distinguish whether the molecules are harmful or beneficial!
Answer:
The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.
The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.
Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
Two of the four major divisions in the geologic time scale are the Archean eon and proterozoic eon.
<u>Explanation:</u>
The Arcean eon is dated from 3900 million years ago to 2500 million years ago. It was in this period the oldest known rocks were deposited. At that time the atmosphere of earth was composed of gases like methane, carbon monoxide, ammonia etc.
The Proterozoic eon is dated from 2500 million years ago to 540 million years ago. It was by the end of Proterozoic era that the Eukaryotas came into existence.
There are some similarities and differences between Archean eon and Proterozoic eon. Stromatolites formed by the colonies of cyanobacteria lived in both the eras. This is one similarity between both the eras.
The weather in the Archean era was hot and wet while the climate and weather of proterozoic era was different from this. Proterozoic era experienced two ice ages.
