Which is a function of nucleic acids?

vazorg [7]

Answer:

The answer to your question is: i have to answer correct first number three and second number one.

Explanation:

1.-regulate cell processes : Nucleic acids are located inside the nucleus and the nucleus is the brain of the cell, it says what functions must be done, then I think this option is correct.

2.- provide structure : Nucleic acids are large molecules but very weak, the couldn't be able to give structure. This option is wrong.

3.- transmit genetic information : The main function of nucleic acids is transmit genetic information, so this option is correct.

4.- fight disease: Nucleic acids are useful to transmit genetic information, and saying the functions a cell must do but fight against diseases is not one of their functions.

What is the maximum radiation pressure exerted by sunlight in space ( s = 1350 w/m 2) on a flat black surface? a. 2. 25 × 10−5 p

mel-nik [20]

The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ P a. So, the correct option is (b).

Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data

Solar constant ( S ) = 1350W / m ^2

Now, the radiaton pressure is given by

P = 2 S /c

where c is the speed of the light

P = 2 × 1350 /3 × 10 ^8

P = 9 × $10^{-6}$ P a

For a black surface, P = 4.5× $10^{-6}$ P a

Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ P a
