NikAS [45]3 years ago

<span>The answer is C. This is because the discovery of the cell and its organelles began with the discovery of the microscope in the 17th century. As powerful microscopes were developed over time, the cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of elements, hence monitoring of biochemical pathways also became possible.</span>

After a big meal, in those individuals who do not have type i diabetes, the pancreas secretes insulin, which circulates through
chubhunter [2.5K]
This is an example of negative feedback. 

After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.

The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules. 

Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).

Hope this helps! :)

Which of these animal would most likely produce antifreeze compound in its cell?
algol13
Antarctic fish. To stop their blood from freezing, some fish that live in the arctic and Antarctic have special Antifreeze proteins. Antifreeze proteins are very clever, as they slow down the formation of bonds between water molecules, which prevents the formation of ice crystals in the fish's blood.

Each lung is fed oxygen by a separate bronchus. Please select the best answer from the choices provided. T F
marysya [2.9K]
Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as they are placed within the rib cages. The lungs actually consists of elastic sacs that contract and expand for taking in and releasing air. This way oxygen is passed into the blood and carbon dioxide is taken out from the blood and passed out. This is also the main function of the lungs.
