Answer:
"
Natural gas does not produce greenhouse gases as other energy sources do."
Explanation:
The answer, "Coal deposits are found on nearly every continent and mining coal poses few risks." shows only how it can be a better option, but does not show how it can benefit.
The answer, "Petroleum is relatively inexpensive compared to other forms of energy." only shows how it can be a better option, but does not show how it can benefit.
The answer, "Nuclear power increases water vapor in the atmosphere." does not clearly state how this benefits us.

Answer:
Species that are broadly distributed are less likely to go extinct than those that occupy a small area or whose habitat is disjointed.
The answer is B. Cnidarians
Cnidarian body has no left or right side, only tom and bottom surfaces. If you divide cnidarian a about central point, you will get equal parts. So, cnidarians are radially symmetrical animals. This group includes hydroids, jellyfish, anemones, and corals. In all groups, animals have stinging cells on tips of tentacles. They use them to capture the prey. Their name literally means stinging creatures.
Answer:
Whenever matter moves from one sphere into another, some process, driven by energy, causes it to happen. Here are some examples: Water moves from a river (hydrosphere) into the air (atmosphere) by a process called evaporation.
Explanation:
Answer:
Acetylcholinesterase enzyme inhibitors are limiting the hydrolysis process of the neurotransmitter acetylcholine, increasing its availability and interaction with specific receptors.
Explanation:
Acetylcholine is a neurotransmitter that aims to stimulate or inhibit the activity of a tissue, by stimulating nicotinic and muscarinic receptors. An example of this is the action of acetylcholine on nicotinic receptors present in the muscle, which promote muscle contraction.
Acetylcholinesterase is responsible for hydrolyzing acetylcholine to make the effect on a receptor end.
In degenerative diseases of the nervous system -such as Alzheimer's- the activity of acetylcholine decreases, so reversible acetylcholinesterase inhibitors are used to limit the neurotransmitter hydrolysis process, increase its bioavailability, and allow the effect of acetylcholine on muscarinic brain receptors.
