Answer:
D. The cell is performing its main function.
Explanation:
The blue section in the diagram represents interphase because a cell spends more time in interphase than any other phase. During this phase, the cell is doing what it usually does, and towards the end, it is preparing for the cell division that will occur.
Answer:
Salut!
- Light enters the eye through the cornea.
- Light travels to the macula within the retina.
- Rhodopsin absorbs light, and the Vitamin A changes shape.
- Vitamin A detaches from the rhodopsin, and some vitamin A is lost.
- Vitamin A from the bloodstream replenishes what is lost. The vitamin A returns to its original shape.
Explanation:
Retina is the part of the eye that contains photosensitive cells that capture light and produce the electrical signals that the brain perceives as images. These photosensitive cells are of two kinds:
Rods contain the photosensitive pigment, rhodopsin that is needed for vision at night or in dim light. Cones function in bright light.
Rhodopsin Bleaching:
Vision in bright or excessive light requires a process called rhodopsin bleaching which is the degradation of rhodopsin upon exposure to light. Upon contact with light, rhodopsin goes through structural changes characterized by the conversion of a pigment derived from Vitamin A, 11-<em>cis</em> retinal to all <em>trans</em> retinal. This chemical conversion initiates a photo-transduction reaction (reaction in which a photon of light is converted into electrical signals) that produces the electrical signals that travel to the brain via the optic nerve. The brain converts the electrical signals to images. This is followed by rhodopsin regeneration in the dark in which all <em>trans</em> retinal is converted back into 11 <em>cis</em> retinal.
The type of organism that is described above would be producers or the plants. They could provide habitat to animals and even to humans. They are the ones who produce oxygen for us to breath by the process of photosynthesis where they take in carbon dioxide from the atmosphere.

<span>I think that the best initial approach to the client by the nurse would be to comfort and first assure the client that she's not there to hurt or harm the client in any way and that no one is judging (s)he and most important that this recommendation is only for the better and to help the client.</span>
