The next day is extremely hot and you jump into the same ocean water. Today the water feels unbearably cold. Did the temperature of the water change? Explain why the water felt so different on both days. Use terms such as hot-free nerve endings, cold-free nerve endings, and desensitization.

Water molecules can pass into a cell, while larger molecules cannot. Which feature of a cell allows this to be true?

Answers

The selective permeability of a cells membrane determine what size and type of molecules can enter or not. If a molecule has a charge and the membrane has a neutral charge the molecule has a harder time diffusing through. The differences in charge affect permeability through a cell membrane.

The cell has a semi-permeable membrane that allows water molecules to pass in a cell while larger molecules cannot. Lipid bilayer is an example of a biological semi-permeable membrane. The diffusion of water is called osmosis. Solutes such as salt and other contaminants are filtered.

How do bacteria help cows to get nutrients from grass?

Answers

The digestive system containsvarious enzymes that can help in the proper digestion of food, and we all knowthat digestive system starts from the mouth.
