Lapatulllka [165]

Answer:

c.) increased glucose uptake to the liver from blood

Explanation:

During stressful conditions such as facing a mugger, the sympathetic system of the autonomic nervous system is activated. There is a release of stress hormones from the adrenal glands to produce the flight or fight response. One of the physiological events occurring during these conditions is the breakdown of glycogen into glucose in liver cells and the release of glucose into the blood. The release of glucose by the liver increases blood glucose levels. This is done to ensure glucose availability as fuel. There is no uptake of glucose from the liver cells under such emergency conditions.

sp2606 [1]

Answer:

<u>Cartilagenous joint</u>

Explanation:

A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur.
