Answer:
Both C and E are reasonable answers.
Explanation:
Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.
A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.
B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.
C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.
D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.
E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.
Answer:
The excess bicarbonate ions are excreted in the urine and the resulting increase in blood acidity leads to an increase in ventilation.

Answer:
The correct answer is -
1. hyaline cartilage
2. fibrocartilage
3. hyaline cartilage
Explanation:
1. The hyaline cartilage covers the articular cartilage of the synovial joint that is translucent or clear as glass-like cartilage that has a firm consistency and a high amount of collagen.
2. A symphysis is an amphiarthrotic joint which is a fibrocartilagenous joint that joins with the adjacent bone. This is a very tough or strong tissue.
3. The growth plate of the long bone or epiphyseal plates are examples of synchondrosis,which is a hyaline cartilage composed tissue.
