Answer:
b. Has risk factors that include atherosclerosis
Explanation:
Ischemic stroke happens when there are underlying factors such as atherosclerosis. Atherosclerosis is caused by clogging of fat and cholesterol in the blood vessels. The reduction in the flow of blood to the brain is usually as a result of blood clumping together and blocking the blood vessels carrying blood to the brain.
The symptoms of ischemic stroke include dizziness, loss of coordination, headache etc.
Answer:
it can be done by oxidation and reduction.
Some nitrogen fixing bacterias are also responsible for converting atmospheric nitrogen into nitrates that plants can use (e.g ribozhium )
bacterias in the soil participate in nitrification as well, oxidizing ammonium ions into nitrates which plants can use.
Explanation:
Oxidation produces nitrate compounds
reduction produces ammoniacal compounds.
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
ATP
Oxygen is the final electron acceptor in the electron transport chain, showing the need for aerobic conditions to undergo such a process. ATP is produced as a product of the electron transport chain, while glucose and CO2 play a role in earlier processes of cellular respiration.
