A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Compare with mitosis.
Answer and explanation;
-The most important life processes in the oceans or sea water are photosynthesis and respiration. Photosynthesis by plants and other lower organisms uses sunlight to convert CO2 and H2O to a carbohydrate compound; O2 is a by-product of that reaction. Respiration is the process that all organisms use to recover the chemical energy stored in organic compounds. O2 is used to oxidize organic matter and release chemical energy; CO2 and H2O are by-products.
-The rates of photosynthesis and respiration are nearly balanced.all of the organic matter produced by photosynthetic algae is respired by consumer and decomposing organisms.
Macrophages are a type of the White Blood Cells that is a part of the immune system of the body. Macrophages are the first line of defence. They engulf the foreign bodies, foreign particles, cancerous cells and infected cells. They do it by searching for a protein marker on the surface of these foreign bodies. When the marker is absent they attack these bodies by performing phagocytosis.
