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.

When we extracted our own DNA last Friday, how did the things we used (Gatorade, alcohol, soap) relate to the things that are us
user100 [1]

Answer:

Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.

Explanation:

In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.

Answer:

As image is not provided,let's discuss about ecological succession.

Explanation:

Ecological succession can be described as the development of a community from its pioneer to climax community. There are two types of ecological succession:

Primary ecological succession: This type of succession occurs in lands where there was no life before or in lands where signs of life have completely been removed like an lava eruption. The rocks in this land are broken down and slowly, pioneer species begin to grow.

Secondary  Succession: This type of succession arises after a natural disaster like fire etc or after any human activity has wiped out the previous community which survived on this land. smalls shrubs and grass starts to grow back on this land, which is replaced by the intermediate species and finally with the climax community.
