Many soil-dwelling bacteria produce molecules that can be naturally synthesized and kill other species of bacteria. What are these bacteria-killing molecules called antibiotics
Antibiotics are effective pills which can be usually safe. Although they are very helpful in fighting disease, antibiotics can actually be harmful. Important Facts About Antibiotic Safety: Antibiotics can cause side effects such as allergic reactions and severe and potentially life-threatening diarrhea caused by the bacterium Clostridium difficile (C. diff).
Antibiotics can also interfere with other medications you may be taking. Antibiotic side effects account for nearly one-fifth of emergency room visits. These conditions are the most common reasons for emergency room visits for children under the age of 18. Taking antibiotics you don't need unnecessarily exposes you to the drug's side effects and denies you the benefits.

Answer:
<em>The correct option is B. It is unchanged and can be used for the same chemical reaction.</em>
Explanation:
Enzymes can be described as proteins which act as biological catalysts. Enzymes can speed up a reaction. During this process, the enzyme itself doesn't get consumed and hence, it can be reused. Enzymes are specific for a particular type of substrate and hence, they can catalyze only those reactions for which they are specific. Hence, option B is correct.
Other options like option A is not correct because the mass of an enzyme will not change after a reaction.
Answer:
Dependent variable: Number of bug bites
Independent variable: Sprayed arm
Control group: Arm not sprayed.
Experimental group: Sprayed arm
Explanation:
If you know the definitions for the independent variable, dependent variable, control and experimental group in a problem than it would be less complicated to figure out what they are in any given example. So, here are the definitions:
Independent variable: the factor that you change
Dependent variable: the factor that is measured
Control group: the factor that is kept the same
Experimental group: the group in an experiment that receives the variable being tested
I had this had a question about this last week and got stumped im sure if this will help you? but I do hope it does and im sure exactly what the entire question is so.... Good Luck!
<span>Evolutionary perspective
The evolutionary perspective is based on the foundations of cognitive psychology as well as evolutionary biology. Evolutionary perspectives on human behavior are almost as old as the science of psychology itself.</span>
