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.

Why are microdeletions and microinsertions difficult to diagnosis using karyotyping?
Harman [31]
Because only the chromosomes can be seen in a karyotype, and microdeletions or insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.

Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin
marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

  • a teen, her required adequate intake (RAI)=  1300 mg/ day
  • an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium=  \frac{270}{1300}  * 100= = 20.8 ≈ 21%

=0.21

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
