1.mitosis and meiosis are similar processes, but they have some very important differences. explain how mitosis and meiosis are alike and how they are different. provide at least two similarities and three differences. 2.photosynthesis and cellular respiration are often described in two ways: 1 they are chemically opposite; and 2 they have a relationship to eachother. explain what these two statements mean. be sure to include the specific substances used and released by each process 3. your skin is constantly producing new cells through cell division. how does this happen? . during interphase, how does a cell prepare for division? describe cell division, including the processes of mitosis and cytokinesis. be sure to describe the mitotic steps. new done

1. Photosynthesis and cellular respiration are often described as been chemically opposite because THE PRODUCTS OF ONE PROCESS ARE THE REACTANTS OF ANOTHER AND VICE VERSA.

The reactants of cellular respiration are glucose and oxygen and these happen to be the products of photosynthesis also. During the process of photosynthesis, plants take in carbon dioxide and water in the presence of sunlight to produce glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, which are the reactants of the photosynthesis process. 

2. Photosynthesis and cellular processes are related to each other, this is because, the photosynthesis process produces the glucose, which cellular respiration used to synthesis energy in the cells of living organisms. Thus, the glucose producing plants depend on the living organisms that carried out cellular respiration to produce carbon dioxide and water, which is the necessary reactants for photosynthesis process. The organisms using cellular respiration also depend on plants to produce glucose and oxygen for their use.

3--during interphase, your DNA replicates (this is how it prepares).during prophase, the nucleur envelope breaks down, spindle fibers are produced (and moving toward opposite sides of cell), and chromosomes can be viewed under microscope, nucleolus disappears .during metaphase, the chromosomes line up in the center.  during anaphase, the two sides of the chromosomes separate, and move toward poles (opposite ends of cell)  

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
