Answer:
Due to the earth's rotation and the gravitational pull of the moon.
Answer:
Answer : Depolarized
Explanation:
Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.
A change in polarity occurs in the axon membrane when a nerve impulse travels across it. At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

Answer:
<u>-blue and red light</u>
Explanation:
Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.
Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.
Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7, B's aldehyde (CHO) ring is bound at carbon 7. Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).
