It’s C. Breeders cross organisms with desirable traits
The answer is C because if you put coral reefs in more places more species of fish will come in hiding it
Active transport, which occurs at the expense of energy.
I believe that the loop of Henle is the hairpin structure that connects the proximal and distal convoluted tubules. The loop of Henle is composed of the ascending and the descending limb. The descending loop of Henle connects the proximal convoluted tube with the ascending limb of the loop of Henle, while the ascending loop of Henle connects the descending limb of the loop of Henle with the distal convoluted tubule.
Carbon would be the answer to this because it is an element while water is a compound. In addition, carbon had 4 bonding sites which allows it to form a variety of molecules like sugars, proteins, and even DNA that are essential for life as we know it.
