Because the environment has a broad range of survivability for many species
Answer:
<h2>
<em><u>Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.</u></em></h2>

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.
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Answer:
The messages carried by neurons are called nerve impulses. Nerve impulses can travel very quickly because they are electrical impulses. ... The sheath covers the axon, like the plastic covering on an electrical wire, and allows nerve impulses to travel faster along the axon.
