Answer:
To maintain body homeostasis
Explanation:
The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:
pineal gland-releases melatonin, controls sleep cycle
pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.
pancreas-secretes insulin and glucagon, control of blood sugar levels
ovaries, testes-reproductive role (release female and male hormones)
thyroid gland-controls metabolism and protein synthesis
parathyroid gland-controls Ca levels
hypothalamus-connects nervous and endocrine systems, controls other glands
adrenal glands-release adrenalin and steroid hormones.
The statement that influenza is a virus that changes over time due to mutations is TRUE.
Because of the mutation changes during time the influenza virus constantly adapts to the changes in the environment.
The virus can mutate it two ways: Antigenic Drift (gradual mutations in the genes) and Antigenic Shift (a sudden change in the surface of the virus).
Answer AND Explanation:
The enzyme maltase combines the substrate Glucose + Glucose to produce the disaccharide maltose. The above occurs through condensation. Maltase is also an enzyme that catalyzes the hydrolysis of the disaccharide maltose to the simple sugar glucose. The enzyme is found in humans and other vertebrates and is thought to be secreted by cells of the mucous membrane lining the intestinal wall.
