The correct answer is pretest and posttest .
A pretest/posttest experiment is an experiment that includes double measurements at multiple points in time. In this kind of test, measurements (measurement of dependent variable) are taken both before and after a treatment.
Answer: homeostasis: is the ability to maintain a constsant body temperature
Explanation: im not sure what you mean by if it had energy homeostasis deals with body temperature not energy but i guess someone can follow me up on this
B is the correct answer to your question
<u>Temperature, pH, enzyme concentration, substrate concentration, and the existence of any inhibitors or activators</u> are a few of the variables that influence enzyme activity.
- The rate of the reaction increases proportionally as the enzyme concentration rises. When diagnosing disorders, this feature is utilized to gauge the serum enzymes' activity.
- The enzymes are highly sensitive to heat changes because they are proteins. Unlike typical chemical processes, enzyme activity is temperature-dependent. Each enzyme has a certain temperature range where it is more active, as you have seen. The ideal temperature, which falls between 37 and 40 degrees Celsius, is at this point.
- When there is a certain amount of enzyme present, the rate of the enzymatic reaction rises as the concentration of the substrate rises until a limiting rate is achieved, after which additional increases in the concentration of the substrate have no effect on the reaction rate.
- The most accurate way to estimate a solution's hydrogen ion concentration (H+) is to use the potential of hydrogen (pH). Additionally, it establishes whether the liquid is basic, acidic, or neutral. In general, liquids with a pH of 7 or lower are classified as acids, whereas liquids with a pH of 7 or higher are classified as bases or alkalines.
- For optimal activity, several enzymes need specific inorganic metallic cations, such as Mg2+, Mn2+, Zn2+, Ca2+, Co2+, Cu2+, Na+, and K+. Anions are also occasionally required for enzymes.

Answer:
A
Explanation:
Here, we want to pick which of the options is a correct answer to being the benefit of naturally occurring forest fires.
The correct answer is that they help to spread the seeds of some trees.
Naturally occurring forest fires ravages the forest and thus work with wind force. They proceed through the entirety of the forest from the point in which they start.
By moving from a particular point in the forest to another point in the forest, they allow for the process of mass movement to naturally occur.
By translocation from one point to another, they take the seeds alongside with them and thus allows for the dispersal of these seeds through the forest
