Answer:

2 molecules of ATP

Explanation:

Glycolysis is the anaerobic process (no oxygen required) used in the breakdown of glucose to extract energy. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. It is the first step of cellular respiration.

Glycolysis is subdivided into two phases: the first phase uses energy (ATP), while the second phase produces it together with pyruvate and NADH.

Two molecules of ATP are required for the first stage of glycolysis, while 4 ATP molecules and 2 NADH molecules are formed in the second stage.

Answer:

The correct answer is - C. Plants.

Explanation:

As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.

In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.

notsponge [240]

Answer:

The correct answer is:

Includes at least two groups, one of which does not receive the experimental treatment. (B)

Explanation:

A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.

<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
