Answer:
Light reactions occur when plants synthesize food from carbon dioxide and water, referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.
Explanation:
Fault Lines. They are weak points in the crust of the earth.
Answer:
The scientists have been studying threats to coral reefs. They have found that coral reefs in the Southeast shore of Australia have experienced increased threats while others in the Northwest shore of Australia have seen a decrease in threat. The most effective way the scientists could use this information to design a new study aimed at developing reef protections is the development of research plan to know the effect of chief independent variables like pollution, habitat destruction on coral reef which is a dependent variable.
Angiosperms have flowers only.
Answer:
E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
