Answer:
The correct answer is glycolysis.
Explanation:
Glycolysis must happen before acetyl CoA can be formed during respiration.During glycolysis the precursor molecule glucose is converted to pyruvate by a series of enzyme catalyzed biochemical reactions.
Pyruvate in aerobic condition is then converted into acetyl CoA by the help of pyruvate dehydrogenase enzyme
Answer: The answer is A. Explains how organisms change in response to the environment.
Explanation: A scientific theory is an EXPLANATION of an aspect in the natural world. In other words, it just tells why something happens. Now it is not just a guess, it is well-supported by evidence and previous studies.
Now to knock out your other choices:
B. is wrong because:
A scientific theory does not predict. It can serve as a basis for a prediction, or what you call a hypothesis, but it does not predict an outcome.
C. is wrong because:
As mentioned earlier, a theory is WELL-SUPPORTED by evidence and previous research.
D. is wrong because:
A theory does not become a scientific law.
Answer:
The exchange of oxygen and carbon dioxide between the alveoli and bloodstream (via passive diffusion)

Ray-finned fishes possess the characteristics of chordates.
<h3>Characteristics of ray-finned fishes</h3>
They are a group of fishes known as Actinopterygii in the Chordate phylum.
Thus, they possess the basic characteristics of chordates, such as:
- Possession of hollow nerve cord
- Possession of notochord
- Possession of post- tail
- Possession of pharyngeal gill-slits
This is in addition to basic features of fishes such as lateral lines, swim bladder, etc.

Glucose turns into ATP or ENERGY during the process of cellular respiration ..
<span>The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yeild of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yeild is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.</span>
