Answer:
im not sure about the answer but i did the test and "The independent variable is the number of dry cells, and the dependent variable is the amount of energy available."is wrong
What do you think energy has to do with the heating systems
Answer:
thermal energy is used to heat water, which is pumped through a system of pipes and radiators. a warm-air heating system burns fuel in a furnace to produce thermal energy.
lactase lowers the activation energy needed to begin breaking down lactose.
lactase releases heat during the breakdown of lactose.
lactase prevents too many disaccharide molecules from clumping together during chemical reactions
The lactase enzyme lowers the activation energy required to begin breaking down lactose. Therefore, option (B) is correct.
The lactase enzyme is a part of the β-galactosidase family, found along the membrane of villi in the small intestine.
In the human body, the optimum temperature and pH for lactase are 37 ° C and 6 pH respectively. Lactase helps in the complete digestion of milk in the small intestine in the human body.
The lactase enzyme catalyzes the hydrolysis of the β-glycosidic bond of D-lactose. After the completion of the hydrolysis, D-glucose and D-galactose are obtained.
The lactase provides the path of low activation energy to initiate the breakdown of the lactose.
Therefore, option (B) is correct that lactase lowers the activation energy.

Answer is: hydroxyl group (-OH).
A functional group is a group of atoms that determines many of the properties of an organic molecule.
Functional group for alcohol is hydroxyl group or hydroxy group (-OH).
In organic chemistry, alcohol and carboxylic acids contain hydroxy groups.
The atoms of functional groups are linked to each other and to the rest of the molecule with covalent bonds.
NH4+
B.
H2O
C.
H2CO3−
D.
H2SO4
Answer:
The answer is B
Explanation:
Answer:
B. H2O
Explanation:
Well, for one example, we know that water is amphoteric... Examples: H2O can become H3O+ or OH-. HCO3- can become CO3^2- or H2CO3
Answer: A = -c + r
Explanation:
Answer:
a = r-c. its that simple I guess
