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.
Answer:the nucleus
Explanation:mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus
Answer:
A few obstacles would make it tough to accomplish this objective. In the first place, the polypeptide backbone is characteristically polar. Hardly any proteins would be dissolvable in a non-polar hydrocarbon. Moreover, to keep up the dissolvability of this protein, most of its amino acids would need to contain hydrophobic or non-polar R groups.
Then again, its charged or polar R groups would need to connect with one another or be covered in the core of the protein away from the hydrocarbon solvent. This would put noteworthy requirements on both the idea of the R groups and the structure of the protein that could take part in substrate recognition or catalysis. By and large, this is certainly not a reasonable objective.
Answer:
The correct answer is option C.
Explanation:
The masses of air move from the areas of high pressure to the areas of low pressure. Pruitt's city must be situated more or less within the equator for it to be dominated by maritime tropical air mass. This area gets adequate sunlight all throughout the year because of the comparative position of the Sun.
Therefore, its atmosphere is usually more heated in comparison to that of the Polar Regions. The air in the tropic regions turns less dense and elevates into the upper atmosphere. The cooler and denser maritime polar air mass from the poles moves in to substitute the elevating air in the tropics, thus, developing incoming cooler winds.
This is the reason for the creation of the trade winds across the globe and distributing energy around the planet to a more or less homeostatic level.
False because cells don’t start diving when they contact a neighboring cell.
