Answer:
A. III only
Explanation:
Cytochromes are found only in the mitochondrial membrane as part of the electron transport chain. They are vital to the downward cascade of energy as electrons are passed from the NAD+ and FAD produced during glycolysis and the Krebs cycle into the electron transport chain to eventually produce ATP.
Answer:
Runoff is one of the ways land water finds its way back to the ocean, so it can join the water cycle again.
Usually, all the water that falls to the land gets soaked in the soil. However, during long rainy periods, or in the spring, when snow and ice glaciers start melting, soil gets oversaturated with water, so this excess water start flowing on the earth's surface. Gravity directs this water from higher to lower areas, where it will flow into some valley river. This river will take the runoff water to another river, then to the sea or the ocean.
Now this water can evaporate and start the water cycle once more.
The monomer of carbohydrates, monosaccharides.
Answer:
Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.
S phase
Explanation:
DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
The ecosystem is an ecological system consisting of all of its biotic and abiotic factors
