Answer:
An autoimmune problem involving the thyroid gland: C. Graves' disease
Hyposecretion of growth hormone: Pituitary dwarfism
Hyposecretion of the pancreas: E. Diabetes mellitus
Hyposecretion of the adrenal cortex: B. Addison's disease
Hypersecretion of growth hormone: A. Acromegaly
Explanation:
Growth hormone is the hormone from the anterior pituitary gland that targets the tissues such as muscles, bones, cartilage, liver, etc. and stimulates the somatic growth of the body. Its hypersecretion leads to acromegaly in adults while its hyposecretion causes dwarfism in children characterized by stunted growth. There is abnormal thickening of specific bones in acromegaly.
Pancreatic hormone insulin serves to lower down the blood glucose levels. Insulin deficiency causes diabetes mellitus characterized by higher blood glucose levels in the affected person.
Hyposecretion of glucocorticoids and mineralocorticoid from adrenal cortex causes Addison's disease characterized by rapid weight loss, lower levels of glucose and sodium in plasma while a rise in potassium levels.
Grave's disease is an autoimmune disease wherein the thyroid gland is stimulated for increased secretion of thyroxine resulting in protruded eyeballs.
Infected sickled red blood cells create a hostile environment for the plasmodium parasite in malaria. The sickle cells have membranes, stretched by their unusual shape, that become porous and leak nutrients that the parasites need to survive and the faulty cells eventually get eliminated quite fast by the organisms, destroying the parasite along the way.

Main parts and their functions :
- Hypothalamus : Links the nervous system to the endocrine system via the pituitary gland. It controls the release of 8 hormones by the pituitary gland, controls body temperature, control of food and water intake, hunger and thirst!
- Pituitary gland : Produces essential hormones for everything living such as the growth hormone, adrenocorticotropic hormone, thyroid stimulating hormone, luteinizing hormone and follicle stimulating hormone, etc.
- Thyroid gland : Produces thyroid hormones that regulate the body metabolism, play an important role in bone growth and development of the brain and nervous system in children!
- Parathyroid glands : Release parathyroid hormone which plays a role in regulating calcium levels in the blood and bone metabolism.
- Adrenal glande : Produce hormones that help the body control blood sugar, burn protein and fat, react to stressors, and regular blood pressure.
- Pineal body/gland : Secretes the melatonin hormone which may help regulate the wake-sleep cycle of the body.
- Reproductive glands : Main source of sex hormones for males and females.
- Pancreas : Has digestive and hormonal functions. One part of the pancreas called the exocrine, secures digestive enzymes. While the other part of the pancreas called the endocrine, secretes hormones called insulin and glucagon. Overall, these hormones regulate the level of glucose in the blood.

#11.) Phacops. It lived in the late Devonian Period (~400 million years ago).
#12.) Carbon-14 is a good radioactive isotope for determing the age of artifacts from a burial site thought to be associated with the most recent early humans because it is present in all organic matter (which humans have, of course).
#13.) 3, Devonian.
#14.) From the Devonian Period through the Triassic Period.
#15.) Cenozoic.
