e Section 17.1 (Page) . View Available Hint(s) Which of the following features is a significant difference in the function of DNA polymerases versus RNA polymerases? See Section 17.1 (Page) . RNA polymerase does not require a primer to add new nucleotides. DNA polymerase extends the growing chain in the 5' to 3' direction, whereas RNA polymerase extends growing chains from 3' to 5'. RNA polymerase, but not DNA polymerase, is an enzyme. Only RNA polymerase adds nucleotide precursors (dNTPs) to a growing chain.

Answer:

The correct answer is RNA polymerase does not require a primer to add new nucleotides.

Explanation:

RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.

   RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.

What statement about the mechanism of hunger and satiety is true?
disa [49]

Answer:

The correct answer is: The ventromedial hypothalamus plays a role in satiety.​

Explanation:

The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.

The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.

Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).

Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.

Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.

Which muscles assist in inhalation when running up the stairs? A) sternocleidomastoid, pectoralis major, scalenes B) sternocleid
Ulleksa [173]

Answer:

Sternocleidomastoid, pectoralis minor, scalenes

Explanation:

During normal inhalation, contraction of the diaphragm and the contraction of external intercostals expands the chest cavity. The increased volume of the thoracic cavity results in reduced alveolar pressure than the atmospheric pressure to facilitate the flow of air into the lungs in response to the pressure gradient.

During deep inhalation as it occurs when running up the stairs, the accessory muscles of inhalation also participate to increase the volume of the chest cavity. The contraction of scalene and sternocleidomastoid muscles increase the volume of the chest cavity further to create a greater drop in alveolar pressure.

During forceful inhalation, the sternocleidomastoid muscles serve to elevate the sternum, the scalene muscles serve to elevate the first two ribs while the pectoralis minor elevate the third through fifth ribs.

Which are common to both aerobic and anaerobic respiration? Select three options.
Gnom [1K]

Answer:

A). glucose

D). carbon dioxide

E). energy

Explanation:

Aerobic Respiration is characterized as the respiration process(metabolic reaction or breaking down of glucose into energy) that occurs in presence of oxygen while anaerobic respiration takes place in the absence of oxygen. The things that are common in both include glucose, energy, and carbon dioxide. <u>Glucose is broken down in both processes(with or without oxygen) while energy and CO2 are the byproducts/released products of the process</u>. Thus, <u>options A, D, and E</u> are the correct answers.
