Cacti and other succulents can adapt to dry climates. They are able to store water in their leaves, while others store water in the roots or trunks. The waxy cuticle helps prevent water loss.
Nucleoid is the answer

Answer:
The answer here is C: the botanist
Explanation:
This is the only plausible answer because geologists study the earth's physical structure and substance. This has nothing to do with the mangroves, so this can't be the answer. The same goes for the anthropologist, who studies ancient human origins. The first option sounds ok, because zoologists study crabs, which are feeding directly on the mangrove trees, and maybe the decline of mangroves is due to them. But they would not be the first scientist to ask, which is the question. The first person to ask would be the botanist, who studies trees. They would be the most likely to know the answer.
The enzyme’s active site binds to the substrate. Since enzymes are proteins, this site is composed of a unique combination of amino acid residues (side chains or R groups). Each amino acid residue can be large or small; weakly acidic or basic; hydrophilic or hydrophobic; and positively-charged, negatively-charged, or neutral. The positions, sequences, structures, and properties of these residues create a very specific chemical environment within the active site. A specific chemical substrate matches this site like a jigsaw puzzle piece and makes the enzyme specific to its substrate.
