Because the surface of a leaf is smooth if the surface was rough the water would get stuck but it is smooth so the water just rolls off
Answer:
Low phenylalanine concentration:
- If the enzyme is inactive, PAH will look like its inactive form, with phenylalanine located in the allosteric site / inactive site so that PAH is a different shape. This will not allow as much phenylalanine to be converted into tyrosine, as we wait for Phe levels to increase.
High phenylalanine concentration:
- If the enzyme is active, PAH will look like its regular form, with an open active site that's the size of phenylalanine so that reactions can occur. (Like a hand fitting into a glove, or a lock into a key.) Phenylalanine will be the substrate, the thing acted upon by the enzyme. This will eventually raise the amount of tyrosine that's created and lower the concentration of phenylalanine.
Think about it like this. Ever heard of homeostasis? That's how the body likes to be the same, keep everything regulated, all the time. So if there are high levels of something, the body is going to try to keep that something down, and if there are low levels, it's going to try to increase the concentration of that thing.
Well...
This question is unclear. but.
A dominant trait always shows over recessive. Unless! Someone has two recessive alleles, otherwise that dominant trait would not show. Cause they don't have it in their genes.

Answer:
A powered exoskeleton (also known as power armor, powered armor, powered suit, cybernetic suit, cybernetic armor, exosuit, hardsuit, or exoframe) is a wearable mobile machine that is powered by a system of electric motors, pneumatics, levers, hydraulics, or a combination of technologies that allow for limb movement with increased strength and endurance.
