Biology
1 answer:
AnnZ [28]4 years ago
3 0

Answer:

D)Oxidative Phosphorylation

Explanation:

Oxidative phosphorylation occurs when the reducing powers NADH and FADH2 are oxidized via an electron transport chain. During their oxidation, the protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient. This gradient drives the facilitated diffusion of protons through proton channels of the ATP synthase and phosphorylation of ADP into ATP. This process of ADP phosphorylation is called oxidative phosphorylation since the energy of the proton concentration gradient generated during oxidation of reducing powers drives the process.

How can a build-up of carbon dioxide in the atmosphere increase Earth's global temperature?
Dafna11 [192]
 Due to carbon dioxide sunlight get trapped in earth's atmosphere, increases the temperature and results in global warming. Due to this glaciers melt and sea level increases and hence coastal areas may flood. The sun's rays reach us in the form of visible light, and raise the temperature of earth. This heat energy warms the earth then goes back into space, and so the temperature remains in balance.

Shtirlitz [24]

Answer:

Option A

Your answer is option A or the "stamen." The stamen is a reproductive organ of a flower that produces the pollen. When a bee visits for a meal of nectar the stamen is the part of the flower that deposits pollen on the bee's body. It's not option B because the sepal functions as protection for the flower, and it's not option C because the petals main purpose is to attract the bees to the flower to pollinate.
