Retinol undergoes oxidation to produce retinal, which when combined with the protein opsin results in the formation of the light-sensitive pigment rhodopsin. You can see in black and white because rhodopsin is the pigment that gives you night vision.
<h3>What pigment is created using vitamin A?</h3>
Rhodopsin, also known as visual purple or the light-sensitive pigment found inside rod and cone cells of the retina, requires the retina as a structural component in order to function.
Yellow, orange, and red fruits and vegetables are colored by a pigment called carotenoids. Some carotenoids can be transformed into vitamin A by your body. The two sources of vitamin A are as follows: Fish, liver, dairy products, eggs, and organ meats are all sources of preformed vitamin A.

Answer: Geologic Eplift and Erosion
Explanation: This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. These sediments could then be compressed to form sedimentary rocks, which would start the entire cycle again.
Good luck! You are smart and you can accomplish anything!
The correct answer is: B) continuous transcription of the structural gene controlled by that regulator
A regulatory gene is gene that encodes for a protein, such as a repressor (or activators) that controls the transcription of another gene or group of genes.
The regulatory gene of a repressible operon encodes for the repressor that inhibits gene transcription. So, when that repressor isn’t active, transcription occurs continuously.
