Licemer1 [7]3 years ago
7 0

Answer: The correct answer is option b.

Explanation:

RNA viruses have RNA as genetic material whereas the host cells usually have DNA as genetic material.

So, in order to integrate its genome with host DNA, the virus must form DNA from RNA, that is, reverse transcription.

It is the process by which DNA is formed using RNA as a template strand.

However, reverse transcriptase (enzyme which catalyzes reverse transcription) is usually not present in host cells.

Thus, RNA viruses carry their own set of enzymes which help in the replication of viral genome and its recombination with host DNA as host cells lack these enzymes.

Other molecules that make up the cells are
Shalnov [3]
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

padilas [110]

According to the research, the correct option is B. A <u>theory</u> is the element of the scientific process that would include the greatest amount of information about living things.

<h3>What is a theory?</h3>

It is a set of ideas or proven hypotheses that explain some phenomenon studied or a scientific description based on a set of observations or experiments.

In this sense, it is a logical system that is established from observations, axioms and postulates, and is formed by the set of concepts, propositions and definitions that are related to each other with the aim of explaining the given phenomenon.

Therefore, we can conclude that according to the research, the correct option is B. A <u>theory</u> is the element of the scientific process that would include the greatest amount of information about living things.

WARRIOR [948]

Answer:

C. NAD⁺  

Step-by-step explanation:

NADH is oxidized to NAD⁺ in Complex I of the Electron Transport Chain.

NADH ⟶ NAD⁺ + H⁺ + 2e⁻

The electrons continue through the Electron Transport Chain, and the NAD⁺ is used in three places during the Krebs Cycle.

(a) Isocitrate to oxalosuccinate

Isocitrate + NAD⁺ ⟶ oxalosuccinate + NADH + H⁺

(b) α-Ketoglutarate to succinyl-CoA

α-ketoglutarate + NAD+ + CoA → succinyl CoA + CO₂ + NADH

(c) Malate to oxaloacetate

Malate + NAD⁺  ⟶ oxaloacetate + NADH + H⁺

The NADH produced by these three reactions can then be used by Complex I in the Electron Transport Chain.
