Eutrophication is a process that leads to enrichment of ponds, lakes and any water body with minerals such as nitrogen and phosphorus. Aquatic ecosystems are diverse and consists of phytoplanktons, zooplanktons, fish and other animals. Too much enrichment of the ecosystem adversely effects the flora and fauna of the aquatic bodies. Eutrophication leads to more uptake of oxygen and increases biological oxygen demand of water. With less oxygen available for animals inside the aquatic systems, they might began to die. Eutrophication is a result of human activities and must be minimized for the betterment of aquatic bodies and aquatic animals. Thus, eutrophication might lead to destroy the aquatic bodies over a period of time.
Water flows from the side of higher water potential (higher water concentration leads to higher water potential) to the side of lower water potential.
This movement is called osmosis. Water potential means the tendency of water flowing away. The higher the water concentration the solvent/solution is, the higher the water potential is and the more likely it'll flow to the other side.
Therefore, if one of the solvents has 10% water and the other has 50% water, water molecules will flow from the one with 50% water to the 10% one. This movement is completely natural and does not require extra energy. The net flow will stop until both sides have the same water concentration. Water still flows through both sides at that time, but no net flow.
Note that osmosis is only the movement of water molecules, with the presence of semi-permeable membrane (which can decide what substances can go through), and the flow of down the water potential gradient. If any one of these is not applicable, the movement is not osmosis.
Answer:
Suppression of one microorganism by another microorganism.
Explanation:
Microbial antagonism is the suppression of one microorganism by another microorganism. For every organism, God creates another organism in order to control its growth and population. So harmful microorganisms that cause diseases in human can be controlled by another beneficial microorganism. If the beneficial microorganisms are removed from the environment, the harmful microorganisms causes more damage to human and their property.
Homozygous for allele A and heterozygous for allele B. So the answer would surly be D.
