The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
It will be C because if a lower energy bonds are formed from breaking higher energy bonds then there will be excess energy to fuel other processes.

Answer:
2. I got you, fam
Explanation:
Think of it like a addition problem, so you are are adding new letters to each square.
First, look at the letters on the outside of the square. There are two uppercase H's and two lowercase H's. These are the alleles of the guinea pigs.
To do Punnert Squares, you are basically adding each of the letters in the squares.
For example, look at the upper left square. There is an H above it and an H to the left. You are going to "add" these to H's to get HH. (Because an H plus another H equals HH).
Then, look at the upper right square. There is an h above it and an H to the left of it (outside the square). Add these two together and you get Hh.
See? Not so bad!
Continue to do this for the lower left square and you get Hh.
This brings you to the fourth, and final, lower right square. Now, there is a lowercase h above it and a lowercase h to the far left of it. This means that the square is going to be hh.
Make sense? This means that your total Punnett Square will look like this (only including the 4-box square):
HH Hh
Hh hh
The first question asked how many Hh alleles does each guinea pig inherit from the mother? Now, looking back at the completed Punnett Square, you can see that there is: 1 HH, 2 Hh, and 1 hh.
So your answer would be TWO, because there are 2Hh in the Punnett Square.
A, b's lifestyle would be constant pain, reduce in height etc.
