Answer:

<h2>C) Amino acids</h2>

Explanation:

The idea of abiogenesis was proposed by the Oparin and Haldane which was later supported by the experiments of Urey and Miller. The thought that life originated from the abiotic molecules.

For this, they tried to create the same environment which was produced billions of years ago that is methane, ammonia, hydrogen gas and electric sparks.  

They found simple organic molecule like amino acids a few days after the experiment was performed. The amino acids are the building blocks of proteins.

Thus, Amino acid is the correct answer.

Which of the following describes the difference between nitrogen-14 and nitrogen-15?
Snowcat [4.5K]

Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.

Vitamin C is required to produce the collagen present in the extracellular matrix.

<h2>Vitamin C</h2>

Vitamin C, or ascorbic acid, is a vitamin that dissolves in water and can be found in citrus and vegetables. Vitamin C is key to preventing and treating scurvy, which is a disease that occurs from Vitamin C deficiency (most of the time due to malnutrition or severe alcoholism); the first symptoms of scurvy are weakness and fatigue, but if it does not get treated properly, it can progress to anemia, hemorrhage, periodontitis, changes in personality, and finally death.

Vitamin C is a necessary element for tissue healing, collagen synthesis, and neurotransmitter enzymatic production. It is vital for immune system function and is necessary for the functioning of numerous enzymes. It has antioxidant properties as well.

Which of the following statements does not describe a way in which fungi differ from plants?
NeX [460]

Answer:

d. Fungi have cell walls made of cellulose.

Explanation:

The cell wall is an extracellular envelope present in all vegetables and some bacteria, fungi and protozoa. Its composition varies according to the habit of each organism before the evolutionary and adaptive processes. This structure precludes morphological changes of organisms, due to its semi-rigid character, that is, cells cannot change shape as a result of spatial impediment limited by the rigidity of the cell wall.

In plants, the cell wall is basically composed of the cellulose polysaccharide, which forms the cellulosic wall. In most fungi, the wall is formed by chitin. Therefore we can state that the statement that does not describe a way in which fungi differ from plants, among the options given is "the fungi have cell walls made of cellulose."
