Answer:
that the salted water osmolarity was bellow 300mOsm/L.
Explanation:
A solution with osmolarity bellow 300mOsm/L is known as hypotonic and will cause a cell to swell and eventually burst if equilibrium is not reached
Answer:
The last one and the second one
Explanation:
Both of those are technically correct. There must be a charge through the book before an electrical force can act on it. Id have to say the last one
Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
Answer:
G1 - S - G2 (may be is option D)
Explanation:
The interface begins with phase G1 where the cell increases its volume and the mass is doubled.
Then, we continue with the S phase where DNA and histones are synthesized.
Afterwardsy we reach the G2 phase where the chromosomes are duplicated.
Finally we reach, the begining of mitosis.
Answer:
Fast Facts: Lipids
- A lipid is any biological molecule that is soluble in nonpolar solvents.
- Lipids include fats, waxes, fat-soluble vitamins, sterols, and glycerides.
- Biological functions of lipids include energy storage, cell membrane structural components, and signaling
There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents.
