1 answer:

3 0

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:

coenzyme A

Explanation:

Coenzyme A is essential. The body produces it and cannot function without it. It facilitates at least 100 chemical reactions in the body. Coenzyme A is considered to be an auxiliary molecule, a chemical that is necessary for the activation of certain enzymes and proteins or important chemical reactions.

Coenzyme A is a molecule - a helper that facilitates the oxidation process. This process leads to the formation of acetyl Coenzyme A - an important substance used for the production of manic acids in a living cell. Without this very important process, there would be no production of fatty acids that maintain the cell membrane.

Label each level of dna packaging in the eukaryotic chromosome with the appropriate term.

Lostsunrise [7]

I assume this photo has the labels you are talking about.

DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin <span>coiled very tightly- 3
Cromosome- </span><span>chromatin condensed even tighter forming a X shape.- 1</span>

How might the trait`s heritability affect the species` ability to undergo natural selection?

Paha777 [63]

Answer: If it is almost impossible for a favorable trait to get passed down to offspring due to reproductive struggles, the species would not be able to undergo natural selection due to a lack in appearance of a trait.

Explanation:

If there are only two organisms with the adaptation, both of which lack any reproductive abilities, the odds of most of the species <em>not</em> dying out are very low. Only those two will have the adaptation and they rest will die out.

I hope I helped! :)
