The function of the following tissues are as follows:
Stratified squamous keratinized epithelium: These tissues cover the surface of the body and present at hair and skin. These tissues are keratinized to protect the surface of body from abrasion.
Simple squamous epithelium: This tissue contain the single layer of flat cells. These tissues are thin and has the ability to pass some selected molecules through the cells.
Hyaline cartilage: Hyaline cartilage contains large amount of collagen that provides support and flexibility to the tissues.
Bone: Bones are made up of calcified material, phosphates and various inorganic ions. Bones provide stiffness and supports the weight of muscles in our body.
Answer:
c. The function of glucagon is to increase blood glucose concentration. All mentioned processes are consistent with this function.
Explanation:
Glucagon is the enzymes synthesized and released by alpha cells of endocrine pancreas in association with food. Glucagon causes an increase in blood glucose levels and it does so by :
1) Inhibiting the process of glycolysis so that the glucose is used less.
2) Stimulating the breakdown of glycogen to increase the glucose concentration in the blood.
3) Stimulating gluconeogenesis in the liver thus increasing the synthesis of glucose in liver.
All these processes directly increase the level (concentration) of glucose in blood.
Hence option C) The function of glucagon is to increase blood glucose concentration. All mentioned processes are consistent with this function is true
