3 0

Answer:

Rats could control the termination of the shocks.

Explanation:

From the experiment carried out by Dr. Weiss, he discovered that rats with high predictability of shock had far fewer ulcers that those who could not control the shocks. Dr. Weiss suggests that this knowledge can be applied to human beings in the fight against ulcers.

The NADPH generated by the pentose phosphate pathway primarily serves as a
Igoryamba

Answer:

Option-A

Explanation:

Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.

The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.

The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.

The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.

Thus, Option-A is the correct answer.

Olenka [21]

Answer:

it is located 1000 nucleotides upstream of the gene’s core promoter - true

it is located 1000 nucleotides downstream of the gene’s core promoter- true

it is in the gene’s coding region - False

Explanation:

These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.
