Answer: the genotypic ratio is 2:2:0
Explanation:
RR x Rr —> RR Rr RR Rr
Cellular respiration is the chemical process that makes energy required for day-to-day metabolic functions of an organism. The resulting energy is in the form of a molecule called ATP (adenosine triphosphate). There are two types of cellular respiration: aerobic and anaerobic, but both types start with glycolysis. Glycolysis is the breakdown of glucose molecules which makes some ATP.
Aerobic respiration uses oxygen. It occurs in the mitochondria of cells. The overall chemical formula for this is
C6H12O6 + 6CO2 ---> 6CO2 + 6H20 + 38ATP
In this process, there are multiple stages: glycolysis, Krebs Cycle, and Electron Transport Chain (ETC). All of these stages are used to make ATP, but ETC makes the greatest amount of ATP. The other stages create reactants needed for ETC.
Anaerboic respiration does not use oxygen and is also called fermentation. It occurs after glycolysis. There are two types of this: lactic acid fermenation,which occurs in muscle cells and produces lactic acid, and alcoholic fermentation, which occurs in yeasts and can make bread and alcohol. The process produces some molecules that can produce more ATP in glycolysis.
Answer:
A. fertilizer runoff from farms, animal manure, and stormwater runoff.
Explanation:
Agriculture and Urbanization are the main factors responsible for the “dead zone” in the waters of the Chesapeake Bay.
In the eastern part of the Chesapeake Bay, you have agricultural activities such as the poultry farms which produce huge amounts of manure that are later washed through runoff into the bay. Also, nitrogen from the use of fertilizers in the farmlands are being washed along into the bay leading to increased level of nitrogen in the waters which reduces the availability of oxygen in the bay. The level of oxygen in the bay is reduced as the excess nutrients that are washed into the bay causes an overgrowth of algae, which later sinks and decompose in the water.
There are many factories located by the western part of the bay where there is also the concentration of urban centers. Much nitrogen is released into the air, which later ends up in the bay.
As a result of urbanization, large volume of water is created in the form of stormwater runoff, as rain falls on driveways, rooftops, roads and other pavement, making difficult for the water to be absorbed into the ground. This large volume of water moves quickly into the bay. Many pollutants such as nitrogen, bacteria, pesticides, trash etc, are washed along into the bay.
