<span>Mitosis is a cell division in which one diploid cell divides into two identical diploid cells. On the other hand, a</span> cell division which results in the reduction of chromosome number by half in daughter cells is called meiosis. Meiosis consists of meiosis I and meiosis II. After meiosis I, the number of chromosomes is reduced by half and the result is two haploid cells. Meiosis II is actually analogous to mitosis. So, in meiosis II, haploid cell divides into two identical haploid cells. In total, meiosis results in four haploid cells while mitosis results in two diploid cells.
Answer:
The carbon cycle shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment.
I have encountered this question before, and the given diagram shows no producers. Moreover, it consists of pictures of five organisms, with no relationship being shown between them. Therefore, in order to make the model more accurate, Maria should add B. The sun and arrows to show the flow of energy.
Answer:
To produce energy in form of ATP
Explanation:
The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors. These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP. Later on these electrons will reach the other photosystem, to produce reducing power. This is in plants.
Cyclic photosystems also exist, in some bacteria, for example, and only produce energy as ATP. They also have an electron transport chain.
Answer:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power.
