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.

Answer:All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere).
Explanation: hope this helps
Answer:
Option A
True
Explanation:
Adenosine triphosphate (ATP) is the molecule in the cells that carry energy. They help to trap the energy that is obtained during respiration and the breaking down of food, in order to release it to the cells of the living organisms when the need arises.
Once the ATP levels deplete in the body, cellular fatigue begins to occur, as the cells do not have the required energy to perform their necessary functions.
This makes the correct option to be A: True. The depletion of the ATP levels in the body causes fatigue
