Answer:

Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.

During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.

This process is the gas exchnage of plants.

How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.

One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as

solniwko [45]

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.
