Answer:
125 molecules
Explanation:
Between two amino acids , one water molecule is eliminated and a peptide bond is formed. When 250 amino acids are joined to form a polypeptide , 125 molecules of water will be removed.
That is, 250/2=125
Prokaryotes: do not have a nucleus, use starch for energy, smaller ribosomes (70s)
eukaryotes: do have a nucleus, use glucose for energy, and have bigger ribosomes (80s)
It happens in glycolysis. It gets broken down into two pyruvates and it happens in the cytoplasm.
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
Volume= length*width*depth
depth=Volume/(length*width)
d=2500/(40*22)
d= 2500/880
depth=2.841ft hope this answer helps you
