In 2Ba(OH)2...
Ba = 2
O = 4
H = 4
Protists belong to the group eukaryotes (having their DNA enclosed
inside the nucleus). They are not plants, animals or fungi but they act like
one. They can be in general subgroups such as unicellular algae, protozoa and
molds. They thrive in environments with little sunlight. But they are not
plant-like organisms. The answer is letter B.
Answer:
* Scientists use genes to explain why evolution happens.
Answer:
It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below
)
Explanation:
Effect of pH on enzymatic activity
PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:
The substrate binding is better or worse than before.
That affects the catalytic speed of the reaction.
The enzymatic speed is measured in M / t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.
I would say leaf cuz they also have different layers :)
Plz give brainiest if I am right
Good luck
