Answer: d. insulin
Actually, there are two hormones secreted by islet cells within the pancreas: insulin and the glucagon. However, their secretions in response to blood sugar levels, are in opposite fashion!
Insulin is normally secreted by the beta cells of the pancreas while glucagon by the alpha cells. The amount of insulin secreted into the blood increases as the blood glucose rises. In the same way, as the blood glucose falls, the amount of insulin secreted by the pancreas goes down.
In glucagon, it is opposite. If blood glucose is high, then there is no glucagon secreted. Therefore, the answer is insulin.
The correct answer will be option- D.
The Pancreas is a small organ which acts as exocrine as well as an endocrine organ.
The endocrine nature of pancreas secrets hormone which helps in maintaining the body functions. The β-cells of pancreatic islets or island of the pancreas secrets a hormone called insulin which helps in maintaining the amount of the glucose in the blood. The insulin helps the body to use the glucose from carbohydrate by binding to the sugar as well as it helps in the storage of the glucose.
Thus, option- D is the correct answer.
The right option is d. Orthostatic hypotension
Orthostatic hypotension is a form of low blood pressure that occurs on standing up from sitting or lying down. It is caused as a result of blood loss, dehydration or aneamia. The most common symptom of orthostatic hypotension is lightheadedness or dizziness which usually last less than a few minutes.
Answer: adverse reactions
The correct answer is: overload their frontal lobes.
The frontal lobes are one of the four major brain lobes found in humans and are located at the front of each hemisphere. Frontal lobes are responsible for many important things, such as voluntary movement, numeracy skills, language and decision making.
The frontal lobes start developing in childhood and keep maturing until early adulthood. Their front part, the prefrontal cortex, is the latest to develop and is responsible for controlling impulses - which explains why kids and teenagers are much more impulsive than adults.
The flocculonodular lobe is in the cerebellum and is involved in moving the head and the eyes in order to maintain balance.
The abducens nucleus (located in the brain stem) coordinates the movements of the two eyes, and the globose nucleus (located in the cerebellum) coordinates the connection between the cerebellum and the rest of the central nervous system.

Overinflated tires and underinflated tires can both cause tire wear. Answer: tire tread wear.
Over time, overinflated tires lead to excessive inner tire tread wear, decreasing the overall lifespan of tires. An overinflated tire is more like to burst.
An underinflated tire is more like to roll The tire pressure is too low, and too much of the tire is in contact with the road. The underinflated tires generate heat, causes internal friction in the tire causing premature outer tread wear.
