Thankkk youuu :)

Explanation / Answer

1 ) An Acid of pH-2.75 is 10 times greaterthan pH-3.75

       pH = -log[H+] = 2.75

       [H+] = 10-pH = 10-2.75

     [H+] = 1.78*10-3

       pH = -log[H+] = 3.75

       [H+] = 10-pH = 10-3.75

     [H+] = 1.78*10-4

2 ) Diffusion is the flow of Random movement of atoms .

            The movement of particles in a solid from an area of high concentration to an area of low concentration.Resulting in the uniform distribution of the substance.

3 ) Osmosis is the movement of a solvent , such as water,through a semi permeable membrane.

4 ) A hypotonic solution is any solutioon that has a lower osmotic pressurethan another solution. In the biological fields , this generally refers to a solution that has less solute and more water than another solution .

5 ) ATP is often called high-energy phosphate compound.

6 ) osmosis and diffusion are PASSIVE TRANSPORT across a selectively permeable membrane .

7 ) The products of fat hydrolysis are 1 molecule of GLYCEROL & 3 molecules of fatty acid.

8 ) In DNA ,the nucleotide adenine pairs with COMPLEMENTARY BASE PAIRING.

9 ) Complement of mRNA is GTCAAGTA
