The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.

Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>
Explanation:
Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .
Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
