lol what?
Explanation:
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

A number is a correct answer
Answer:
E
Explanation:
Aerobic respiration mainly occurs in the mitochondria of the cell and is known as the Krebs/Citric acid cycle. It begins when pyruvate from anaerobic respiration in the cytoplasm which is converted to acetyl-CoA before entering the Krebs cycle. Acetyl-CoA is transformed and the energy in its bond used to enable oxidation of NADH and FADH2. The H+ ions are pumped to the mitochondrial intermembrane space. The generated proton motive force is then used to generate ATPs by ATP synthase enzyme. Oxygen becomes the ultimate proton acceptor which is reduced to water. This whole process is facilitated by enzymes in the cell such as dehydrogenases.
The organism number gets smaller from kingdom to species. Kingdom includes all the plants or animals and species includes the same type of plant or animal. Generally plants or animals. There are actually six kingdoms but the same rule applies.
