Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
Plants can use the fixed nitrogen in the ground to help them grow.
Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
- The rate of bacterial cell reproduction varies from a particular species to another.
- Varying species have different absorbance thresholds.
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
The answer is A. a gene is a form of a trait, and alleles make up genes
