Explanation:
Explanation:
Each has one chlorin ring- chlorin is a form of porphyrin.
Chlorophylls are comprised of a ringed molecule, chlorin, a hydrogenated form of porphyrin which contains a magnesium ion at the center, bonded to four atoms of nitrogen. Varying types of Chlorophyll have side chains, which affect the absorption spectrum of the molecule for instance A has a methyl group bonded to the C7 position, while B has an aldehyle (CHO) group at this location.
Embedded within the thykaloid membrane of chloroplasts, chlorophyll a and B mainly absorb orange-red and violet-blue wavelengths and convert light energy into chemical energy for the process of photosynthesis. This occurs in the light-dependent reactions of photosynthesis, within chloroplasts of plants. The range of wavelengths absorbed by a pigment is its absorption spectrum while it reflects those outside of this range. Plants appear green as this region of light is reflected by the pigments.

B! Cardiac muscle hope it helps sorry if it doesn’t!
Answer:
Explanation:
Increased nitrogen level in ocean water can lead to excessive growth of aquatic plants in the ocean which in turn leads to high oxygen (dissolved oxygen) uptake by these plants when they decompose. The overgrowth of these plants also prevent light penetration in the ocean water. All these can affect other aquatic organisms particularly those that depend on these dissolved oxygen and/or light penetration (such as fish and crustaceans).
<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer. Obviously we can't say whether chickens will have teeth with certainty, the chickens with teeth are clearly still chickens, and a baby croc isn't hatching out of a chicken egg any time soon.
