1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
Answer:
The correct answer is C. helps process explicit memories for storage.
Explanation:
The hippocampus is an structure of the brain and is located inside the temporal lobe. The main function of the hippocampus is to mediate the generation and recovery of memories in conjunction with many areas spread across the cortex and with other areas of the limbic system. It helps to process and recover the episodic memory (those related to events) and spatial memory (mode in which we perceive space or dimensions). This organ is also where short-term memories become long-term memories, that is, it acts as a mediator of memories, acting as an activation node that allows different memories distributed across different parts of the brain to be activated.
Answer:
In most tissues of the body, the response to hypoxia is vasodilation. By widening the blood vessels, the tissue allows greater perfusion. By contrast, in the lungs, the response to hypoxia is vasoconstriction.
Explanation:
Ans. An isotope of Hydrogen called Tritium has one Proton and two Neutrons and its mass is 1
