Answer:
competition
Explanation:
After an ecosystem has been destroyed because of certain catastrophe and all of the space that it occupied is totally cleared and open for overtaking, the primary succession comes in action. When the primary succession occurs, there's no competition, as pretty much everything has been destroyed from the previously existing ecosystem. The pioneers of the primary succession are organisms that do not require a lot to prosper, such as the mosses and lichens. As they start to cover the barren land, little by little they manage to change the composition of the rocks, thus resulting in the formation of the first soils. As that happens, the secondary succession comes on the horizon as now it has conditions for it, so the species from it overtake and replace the species form the primary succession.
For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change
Answer: Nucleus Acids
Explanation: Nucleic Acids hold and store DNA (think Nucleic/Nucleus)
The answer is D, being breathed into the lungs.
Answer:
NADPH
Explanation:
Light-dependent reactions form the NADPH when the electrons from the water molecule are passed from PS II to PS I and finally to the NADP+. The enzyme NADP reductase catalyzes the reduction of NADP+ into NADPH. The enzyme is located on the stromal side of the thylakoid membranes and therefore, the NADPH is released into the stroma. Stroma is the site for the reaction of the Calvin cycle. During the Calvin cycle, the reduction of 3-phosphoglycerate into glyceraldehyde 3-phosphate uses NADPH as the electron donor.
