how could you increase the rate of the reaction in part C of the above image? select the best response based on the information given
a. expose the reaction to sunlight
b. decrease the amount of reactiant(s)
c. change the temperature
d. increase the amount of enzymes
Answers
Answer:
c) change the temperatureTo increase the rate of the reaction in part C of the above image, change the temperature. Thus option C is correct.
what are the factor affecting the rate of reaction ?
At higher concentration of reactants, more collisions leads to increase the rate of the reaction.
Changing the pressure can change the concentration leads to high number of collisions caused increases the reaction rate.
If a reactant is a solid and grinding of these reactants can increase the surface area, will lead to faster the reaction.
Increase in temperature, means molecule have higher average kinetic energy and more collision causes an increase in the reaction rate.
The medium in which the reaction occurs is another factor like in aqueous solution the reaction go faster.
Catalysts lower the activation energy followed by increase the rate of a chemical reaction.
Thus option C is correct.

What would an organism need to do to release energy
from a carbohydrate, a lipid, or a protein? What two
elements are involved?
Answers
Organism needs enzymes in order to release energy from carbohydrate, a lipid, or a protein.
Amylase is the enzyme which is responsible for the breakdown of carbohydrates secreted by salivary glands. Pepsin, trypsin and chymotrypsin are the enzymes responsible for the digestion of proteins while on the other hand, lipase is the enzyme that is responsible for the digestion of fats in the body so we can conclude that enzymes are required by the organism for the release of energy.

What plant and animal breeders process artificial selection?Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits. Humans have carefully selected a wide range of plants and animals for thousands of years, including agricultural species with higher yields.
Instead of allowing the species evolve spontaneously without human involvement, as in natural selection, people chose animals or agricultural products based on desirable qualities, a practice known as "selective breeding,” or artificial selection.
Therefore, The breeders choose organisms with the most desirable traits and breed them.
