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).
(C) earth's outer iron core
this is because iron is magnetic and therefore forms a strong magnetic field
Answer:
Option (B).
Explanation:
Heart is the main pumping organ of the body. The human heart is divided into four chambers that are right atria, right ventricles, left atria and left ventricles.
The left and right ventricles can easily be distinguished on the basis of their thickness. The right ventricle is less thicker than left ventricle. The thickness of right ventricle is 9mm whereas the thickness of left ventricle is around 40mm.
Thus, the correct answer is option (B).
