The statement that explains why randomized controlled trials are often "double blind" is as follows: to decrease bias by ensuring both the participants and researchers do not know who is receiving the treatment and who is not (option B).

<h3>What is a double blinded experiment?</h3>

Double-blinded experiments are forms of scientific testing in which some information is withheld from two different parties.

In summary, neither the tester nor the subjects tested know which are the control items and which are the test items.

A double blinded is conducted to reduce or eliminate bias between the participants and researchers.

Therefore, the statement that explains why randomized controlled trials are often "double blind" is as follows: to decrease bias by ensuring both the participants and researchers do not know who is receiving the treatment and who is not.

Mammals store Extra glucose in the form of a compound called glycogen. What molecule supplies the energy needed to join glucose
bekas [8.4K]

ATP is the molecule that supplies the energy needed to join glucose molecules together to form a molecule of glycogen.

Explanation:

ATP is the energy currency of cells. It is used to power all non-spontaneous biochemical reactions in the body including the conversion of glucose to glycogen.

Glycogen has a higher Gibbs free energy than glucose (because it lowers entropy) meaning you need energy to convert glucose to glycogen. This reaction does not occur spontaneously because of it akin to ‘climbing a hill’. ATP is involved in the condensation reaction of joining glucose molecules together into glycogen via glycosidic bonds.

Read the passage.
vlada-n [284]

A comma splice is basically a comma fault which means- when two independent clauses are joined by a comma to make one complete sentence. And an independent clause is a clause that can stand alone as a sentence.

So, here in the passage- Option C is correct one.

Lady Liberty is a woman holding a torch, it represents freedom. This sentence can be successfully broken into two complete sentences. Like- Lady Liberty is a woman holding a torch. It represents freedom.
