<u>Answer</u>:
Metabolic regulation D: Is the maintenance of homeostasis at a molecular level
<u>Explanation</u>:
Homeostasis means resistance to change to maintain a stable and constant internal environment in organisms. Body maintains homeostasis for many reasons like to maintain temperature, controlling pH and glucose levels. If these levels fluctuate, person can get sick.
Metabolic regulation provides an ideal homeostasis mechanism. It is a process by which body takes in nutrients in the form of food and energy is being delivered to us. Metabolic regulation includes regulation of an enzyme in a route of the body by responding either less or more to signals.
Answer:
This is a right and scalene triangle with sides 4, 6 and 7.21
Explanation:
One way to solve this problem is to locate the three points of the triangle in the Cartesian plane to have a graphical idea of this triangle. As you can see on the image, this is a rectangle triangle, therefore we can determine with the plane the length of both legs and then with the Pythagorean theorem find out the hypotenuse as follows:
Therefore, we have a triangle with three sides of different length, and that corresponds with a scalene triangle.
Answer:
Populations evolve as natural selection results in a change in the frequency of alleles within the population over time.
Answer: Enzymes speed up the rate of the reaction without changing the ΔG for the reaction.
Explanation: Enzymes speed up the rate of the reaction without changing the ΔG for the reaction.
Enzyme (E) binds to the substrate (S) to form an enzyme–substrate complex (ES) products are formed at the end of the reaction but however, the enzyme remains unaltered, it can still bind to another substrate and/or can be reused as many times as possible.
Enzymes accelerate the rate of reaction by decreasing the activation energy.
Temperature affects the activity of enzymes, increasing it to reach a limit, which corresponds to the optimal enzyme activity. If the temperature goes beyond this maximum limit, enzymatic activity declines. The optimal temperature for most animal enzymes is about 37°C. The inactivating effect of temperature is due to protein denature.
