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
