the answer is Natural energy resources are nonrenewable and are being depleted.
Basically, the cell wouldn't be able to "breathe," as the mitochondria is where the respiratory functions of the cell happens. No energy would be produced, and then the cell would stop moving and die.
Seasons are Winter, Spring, Summer And Fall. The Sun moving (orbiting earth) causes them. So in the winter, the sun is on the opposite side of the world, and that's why it is so cold. In the summer, the sun is facing straight at us. Other season's, the sun is kinda in between, if that is any help
B is correct, Organisms in the same group have similar characteristics
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.
