Answer:

1. The correct answer would be oxygen.

Oxygen is used as the terminal electron acceptor in cellular respiration. It results in the production of water (byproduct) from oxygen.

2. The correct answer is the third option, that is, Cellular respiration produces more ATP molecules than fermentation.

Fermentation takes place in absence of oxygen which results in the production of lactic acid (or ethanol). In absence of oxygen, glucose does not break down completely due to which less number of ATP is produced.

Fermentation only produces 2 ATP molecules per glucose molecule. In comparison, cellular respiration produces 36-38 ATP per glucose molecule.

3. The correct answer is option third.

The light energy is used to phtolysis of water which releases oxygen and high energy electrons. These electrons are then used to produce NADPH and ATP. These NADPH and ATP are then used in dark phase to fix carbon into glucose.

Explain how a streamlined, smooth, nearly hairless body is a beneficial adaptation for marine animals.

lana66690 [7]

Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.

What was antoine lavesters results for after his series of experiments

FinnZ [79.3K]

In experiments with phosphorus and sulfur, both of which burned readily, Lavoisier showed that they gained weight by combining with air. With lead calx, he was able to capture a large amount of air that was liberated when the calx was heated. To a suspicious Lavoisier, these results were not explained by phlogiston

Describe the relationship between proteins and nucleic acid

Dmitry [639]

Answer:

Explanation:

Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
