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.
C. To track the direction the outdoor sunflower heads were facing throughout the day.
Explanation:
The main aim of the experiment being conducted by Jane is to track the direction the outdoor sunflower heads were facing throughout the day.
The whole set up is designed to test the claim that sunflowers do follow the sun in the sky throughout the day.
- From experiment, Jill should be able to track the changes in the orientation of flower head throughout the day.
- This will rightfully support his claims .
