Answer:
abt 24 contraction per min is needed to maintain a relatively stable internal solute conc.
paramecium maintain its volume by preventing itself from shrinking by holding in as much water as it can.
When the water solute concentration is reduced, the number of vacuole contractions will increase. But when the water solute concentrations rise, the number of vacuole contraction will decrease.
When the number of vacuole contractions will increase, the water solute concentration is reduced. But when the water solute concentrations rise, the number of vacuole contraction will decrease. So it is cetris paribus, means when the one is increase the other one will decrease.
The answer is Silurian period (443 million to 416 million years ago). This was the era when life in the seas and oceans began to conquer land. This is associated with a period of warm climate, rising sea and ocean levels hence giving shallow-water grounds where reefs developed. Plants like bryophyte began to develop including the emergence of terrestrial arthropods

If your body lacks enzymes that break down
carbohydrates, it would be unable to get sugar molecules for energy production.
If you lacked the enzyme to digest proteins, you may not absorb enough amino
acids.
The digestive system in our body changes
carbohydrates into glucose; also known as blood sugar to be use as an important
source of energy. Meanwhile, amino acids are organic compounds that combine to
form proteins, which are the building blocks of life.
Answer:
C
Explanation:
The production of ATP is greatest at 50o C as indicates by the production of CO2 in the Krebs Cycle

This question is incomplete; the complete part is:
Which of the following best explains the reactions of these enzymes?
A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.
B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.
C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.
D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.
The answer is A
Explanation:
In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.
Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).
On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.
