Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.
The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.
The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

Answer:
The correct answer is option C.
Explanation:
Human subject research is an investigation or research that include human as the subject. In other words, An Investigator conducts clinical research on humans getting data through interaction and intervention of individuals.
investigator A has investigated biological specimens. These specimens are coded and linked to the identifiers. Investigator B's research using biospecimens human subject is not according to the human subject research in the federal regulations as investigator B did not get the individual identifiers.
Thus, the correct answer is option C.
Answer:
C) maleness results from the minimal presence of one Y chromosome
Explanation:
- From the given question, it can be clearly observed that in males irrespective of whichever syndrome they have a Y chromosome is always present whereas in females Y chromosome is not present.
- Hence, one cal conclude that whenever the Y chromosome is present the individual acquires male characters.
- The Y chromosome whenever present produces the hormones that leads to maleness, and the number of Y chromosomes in males can also be more than one such as in case of XYY Klinefelter syndrome.
The answer to this question is : <span>They tolerate both freshwater and salt water.</span>
