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.
The correct answer is
Because the needle can't hold as much heat as the bucket of water. Therefore the water can hold and disperse more heat and the needle will be hotter.
Answer:
In the presence of oxygen, respiration of yeast produces carbon dioxide and water. In the absence of oxygen, respiration of yeast produces carbon dioxide and alcohol.
Under the assumption that the yeast has insufficient exposure to oxygen in the surrounding air in the testtube, alcohol and carbon dioxide would be expected to be found in the test tube
