<h3><u>Answer</u>;</h3>
Photoreception
<h3><u>Explanation</u>;</h3>
- <em><u>Photoreception is a type of reception of light detection that lead to vision and depends on specialized light-sensitive cells called photoreceptors, which are located in the eye.</u></em>
- Photoreceptors are the cells in the retina that respond to light. There are 2 types of photoreceptors in the retina namely; rods and cones. The rods photoreceptors detect light and are located in the retina. Cone are photoreceptors that are located in the retina and detect color.
The correct answer is: They usually have one or more helical regions spanning the membrane bilayer
Transmembrane proteins are type of integral proteins meaning that they are permanently attached to biological membrane. Transmembrane proteins span through the plasma membrane so most of their structure is hydrophobic.
The major role of these proteins is transport role: they act as a channels that undergo conformational change in order to move a substance through the membrane.
Classified by their structure they can be put into two types: alpha helical and beta barrels.
Evolution and paleontology.

One word. R͟e͟p͟e͟t͟i͟t͟i͟o͟n͟.
Study one small part at a time, over and over. Ask questions and stay after school. Do research and flash cards. All the help you need is there. You have to do your part and dedicate yourself into your class. There isnt a sufficient way to cram information in when you have a test next day, but next time you should do an little something helpful called, s͟t͟u͟d͟y͟i͟n͟g͟.
