I’m not 100% sure if that’s right but I tried
If the sun produced less energy plants would not survive. They would lose the capability of photosynthesis and cellular reproduction. Due to this factor animals and humans would die out, simply because we would suffocate. That doesn't even cover how the sun will affect the atmosphere. Gases wouldn't evaporate and the perfect balance on Earth would dissipate, because the gas would tear at the atmospheric layers.
Answer:
B. Curare will only affect muscles with ACh receptors, paralyzing them.
Explanation:
Acetylcholine receptors are located on the surface of muscle cells, especially in the synapse between muscle cells and nerve cells. Muscles are constantly pumping sodium out of their cells, so, when they are relaxed, there is more sodium outside than inside. When they get the signal from the nerve, the channels open and sodium ions get back inside, starting the process muscle contraction. IF curare binds to the site where Acetylcholine is supposed to act, and thus blocking all this muscle contraction signal, it will produce a progressive paralysis of all muscles.
This is usually called a placebo. They are used as control tests to make sure that a product actually works. A placebo, however, is not merely restricted to pills, though.
