The valve that controls the passage of chyme from the small intestine into the cecum is called the:
ileocecal valve.
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
Increasing the number of capillaries associated with alveoli would be expected to increase carbon dioxide being carried to alveoli.
Alveoli are the very small air sacs at the end of the bronchioles. Each alveolus is cup-shaped with thin walls, and It is surrounded by networks of blood vessels which are called as capillaries that also have very thin walls. The oxygen we breathe gets into the blood through the alveoli and capillaries. The Red blood cells travel through the capillaries. Alveoli's walls share a membrane with the capillaries. Oxygen and carbon dioxide get in and move freely between the human respiratory system and the bloodstream.
Oxygen molecules are attached to red blood cells, which travel back to the heart, and at the same time, carbon dioxide molecules in the alveoli get out of the body.

Answer:
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
