Help! Another Time crunch question! In the phospholipid layer of a cell membrane the ends of the phospholipids are on the outside.

1. hydrophilic

2. hypotonic

3. hypertonic

4. hydrophobic

I think it is Hydrophobic, but really would like a second opinion! Thank you!

answer; i believe that the correct answer is; ///bodies of water store heat during the day and release it at night;

the wires in the toaster turning red and the toast crisping and turning brown

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
