Answer:

a) the oxidizing agent.

Explanation:

In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.

Objective means that they are "facts", and do not include personal thoughts and beliefs (which is subjective).

In this case, your answers are:

1) Fact:

Facts are made based on data and analysis, and are supported by details and other known "facts" or <em>truths</em>. This means that they are right in any circumstances in most cases, or at least in the given circumstance that is provided.

2) Data:

Data is used to support the fact, which is objective. Without data, the claim would be seen as a opinion, or subjective, in meaning, a "I feel that it is this way". Without data, you will not have facts.

It is not:

3) Opinion:

Opinion is the antonym of Fact, and so if Fact is a answer choice, then Opinion is not. Opinion is based off of feelings, personal knowledge, and personal preferences. While useful in some cases, it is not objective.

4) Theory:

A theory is not objective, because it is a opinion that is provable (but is yet to be proven). This makes it subjective, until proven right.

Chloroplasts and mitochondria are thought to be of prokaryotic origin. One piece of evidence that supports this hypothesis is th
ivanzaharov [21]

Answer:

The correct answer will be - in the bacterial cells

Explanation:

The complexity of life began on Earth when the simple amoeba-like organism started ingesting the bacterial cells. The ingestion of the aerobic respiration performing bacteria formed the mitochondria and ingestion of the photosynthetic bacteria formed the chloroplast of the cell. The bacteria while evolution lost their identity and now cannot live without the host cell.

This hypothesis was supported by the evidence like a comparison of the Ribosomes of this organelle is similar to the prokaryotic bacteria as the bacterial cell.

Thus, in the bacterial cells is the correct answer.
