Question 2
Codominant alleles assort independently.
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.
I believe this would be the cerebellum. This part of the brain is used for motor control like moving the fingers say and cognitive functions (to do with thinking) and also can affect the feelings of pain and pleasure.
The
correct answer is mutualistic bacteria in the hindgut of the termite digest the
cellulose into sugars.
<span>
Termites
depend upon the whole complex of microbes in their hindgut. Microbes inside the
termites help the breakage of the complex sugars like a cellulose into short-chain
fatty acids.</span>
Which simple machine can be described as a rope that is threaded through a wheel or disk?
The correct answer is B - Pulley
A pulley is a simple machine that is used to lift loads. It consists of a wheel on which a rope is placed and the rope is pulled by the person towards himself to lift the load that is tied on the other side of the rope. There are three main types of pulleys: fixed, movable, and compound.
