Answer: I would go with B. Here’s why: An index fossil is usually easily recognizable, and underwent a wide geographic distribution. What leads me to believe B is the correct answer, is because it’s something that existed “ all over the world”.
That would be A the internet told me
Answer: water potential is the measure of the energy of water to move from one area to another.
Explanation: water potential effects osmosis in a way that water needs to move through membrane and for this movement it requires pressure which makes water potential high so water movement will be faster across the membrane. Water potential determines water movement in osmosis that water move from high water potential region to low water potential region. If water potential is high inside than outside, then water movement to outside will be more.
If water potential is high outside than inside then water will move more inside. If water potential is the same in and outside then water movement inside and outside will be same and this will be called as equilibrium.
a. that are all affected
Since the father is homozygous dominant (AA), and he is affected, that means that the disorder (or whatever it is), is autosomal dominant (plus it directly tells you that). That means it is not carried on the sex chromosomes. Since every child he has will inherit one of his alleles, they will all be affected by having at least the one.
