Answer:

Insulin and glucagon are both hormones secreted by the pancreas to help maintain proper blood glucose levels. Insulin is secreted to help lower blood glucose levels. Insulin allows to cells to take up glucose from the blood to be put into storage. Glucagon is secreted to help raise blood glucose levels. Glucagon allows storage cells to release glucose back into the blood so blood-glucose is returned to normal levels.

Question:

All living things are made up cells. There are two main types of cells: prokaryotic and eukaryotic. What are the characteristics that make each of these types distinct from each other?

Answer:

Prokaryotic cells are single-celled organisms that lack membrane bound organelles and a distinct nucleus. These cells usually consist of basic 3 components: nucleoid (DNA-genetic material), ribosomes, and a cell membrane. Eukaryotic cells are the cells that make up multicellular organisms. They contain an abundance of membrane bound organelles and a distinct nucleus. Eukaryotic cells contain mitochondria for energy harvest and a cytoskeleton that supports the structure of the cell.

Question:

The human body requires a specific fluid and electrolyte balance in order to function properly. There are 3 different types of solutions that bodily fluids can be under based on water and solute concentration. What are the 3 different solutions? What happens to cells under each solution condition? Which is the most ideal for the human body?

Answer:

The 3 different solutions are hypotonic, hypertonic, and isotonic. An isotonic solution scenario is the best for the human body. This solution indicated that water and solutes are evenly moving in an out of body cells. This solution keeps the body balanced. A hypotonic solution means that the solute concentration is higher inside the cell. This will cause water to move inside the cell, which can cause the cell to burst. This type of solution usually appears when the body is over hydrated . A hypertonic solution means that there is a higher solute concentration outside the cell. This will cause water to move outside the cell, which will cause the cell to shrivel. This type of solution usually occurs when the body is dehydrated.
