The answer is definitely B
The barrier between the intracellular and extracellular fluid compartments in an animal or plant is the <u>plasma membrane</u><u>.</u>
The plasma membrane or cell membrane is a double membraned cell organelle that surrounds and protects the cell and other cell organelles. Both prokaryotic and eukaryotic cells have a cell membrane.
The plasma membrane is about 5 - 8 nm in thickness and is composed of proteins, lipids and carbohydrates that come together to form a flexible bilayer. This lipid bilayer gives the cell membrane its ability to separate intracellular and extracellular fluids.
The plasma membrane also plays a role in signalling and communication between cells and anchors the cytoskeleton to provide cell shape and maintain cell potential.

Answer:
D) A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied.
Explanation:
When we do a monohybrid cross, we look at one characteristic at a time. When you do dihybrid cross, you are looking at characteristics.
Monohybrid cross example:
If black fur (B) is dominant over white fur (b) what is the probability of black fur in an offspring between two dogs heterozygous for the trait?
Bb x Bb
B b
B BB Bb
b Bb bb
So the probability of black fur is 75%.
Dihybrid example:
If black fur (B) is dominant over white fur (b) and short hair (S) is dominant over long hair (s) what is the probability of white fur and long hair in an offspring between two dogs heterozygous for both traits?
BbSs x BbSs
BS bS Bs bs
BS BBSS BbSS BBSs BbSs
bS BbSS bbSS BbSs bbSs
Bs BBSs BbSs BBss Bbss
bs BbSs bbSs Bbss bbss
The answer would be 1:16 = 6.25%
