<span>One process wherein diffusion is important is the concentration of salt within a cell. When the salt levels are too high within the cell, salt molecules are moving via diffusion to a region of lower concentration. Another process is the movement of carbon dioxide in plant cells, where CO2 moves from regions of high concentration to regions of low concentration.</span>
Answer:
A. two haploid gametes fuse to form a diploid cell
Explanation:
Meiosis is a type of cell division. When a parent cell with "2n" chromosomes enters the process of meiosis, four daughter cells each with "n" chromosomes are formed. This occurs since homologous chromosomes separate from each other during anaphase-I. However, meiosis does not include the fusion of two haploid cells. The fusion of two haploid cells mainly occurs during the process of fertilization during which a haploid male gamete and a haploid female gamete fuse to form a diploid zygote.
Answer:
The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.
Another one is that the species multiply rapidly and easily.
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
