Explain Cellular Respiration clearly.
aleksley [76]
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.

what probability do we have of obtaining a purple flower (Rr), when we combine two blue flowers (rr) in an incomplete Dominance
34kurt

Answer: none

Explanation:

If we have that the color characteristic is regulated by the dominant gene R, by crossing two blue flowers with the recessive gene r, no violet flower will be obtained, since the rule of incomplete dominance describes that phenotypes can be obtained intermediates of homozygous parents, however in the case, we only have 2 parents with the same recessive conditions, which do not contribute to generate the violet, to produce one of the parents should have a gene that expresses the color red

Small, wandering cells that engulf cell debris and pathogens in the CNS are called
Marrrta [24]

Answer:

D. Microglia

Explanation:

Microglia are phagocytic, which means that they are cells that can engulf other cells and particles. Microglia protect the CNS by engulfing foreign particles and bacteria. They act also as a clean-up crew that help remove dead cells. They are found in both the brain and spinal cord, which make up the Central Nervous System, or the CNS.
