Answer: Messenger RNA Carries the Instructions for Making Proteins. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm
Answer:
A.
Explanation:
Choice B is incorrect. That definition can be applied to both DNA <em>and </em>RNA, as they are both made of a nucleic acid, phosphate, sugar ring, and nucleotide base.
Choice C is incorrect. That would be the message strand made by RNA when they are transcribed.
Choice D is incorrect because it's absurd.
Answer:
9600 cm/min
Explanation:
Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.
10 radians per second divided by 2π is the number of revolutions per second.
So multiply that times the circumference and that's the distance the point has traveled.
let the linear speed of the spot be v
therefore, v= 160×60= 9600 cm/min
<h2>Chemical energy</h2>
Explanation:
Chemical energy describes the energy conversions that occur during the light-independent reactions
- Photosynthesis is completed in two reactions namely light reaction and dark reaction
- Light reaction is the light dependent reaction which means that there is direct role of light
- It oxidizes water,release oxygen and generates high energy compound such as ATP and NADPH(all the reactions are completed in thylakoid membrane)
- Dark reaction is the light independent reaction which means there is no direct role of light
- It utilizes carbon dioxide to form carbohydrates and consume ATP and NADPH for synthesis of carbohydrate(Calvin cycle)
- All reactions are completed in stroma
- Fixation of one carbon dioxide molecule requires 3 ATP,2 NADPH,2 water molecules and 8 photons
