The answer that I got is C.
Creating awareness will always be a solution , but doing something about it creates improvement to the global issue . You can create biodegradable plastics so whenever the biodegradable plastic hits the ocean , the object can become food for the ocean animals instead of harming them ......some McDonald’s are now changing their straws (biodegradable straws ) so change is happening slowly we just need awareness
Answer:
Infectious dose refers to the minimum number or amount of pathogens required in order to produce a disease or its symptoms. In the given case, the bacterium is non-resistant and is treated with antibiotics.
The antibiotics help in neutralizing the infectious agents; however, full course should be done to eliminate the infectious agent completely out of the body.
If the course is left in between then, there are very high chances that some bacteria may survive. They might not produce disease or symptoms as they would be less than infectious dose.
However, with time, the survived bacteria gain more and more mutations during replication which can develop antibiotic resistance capability in them.
In addition, it is also possible that the survived bacteria can get R-plasmid (which has antibiotic resistant gene) from body's normal flora or from any other infectious agent present in the body by the process of transformation or conjugation.
The R-plasmid enables them to survive even in the presence of antibiotics due to which the treatment of the disease might become difficult.
So option B (hybrids have lower fitness than either parent population) is the correct answer.
What is Reinforcement?
Reinforcement is a consequence used in behavioral psychology to strengthen an organism's future behavior when that activity is preceded by a specific antecedent stimulus. This strengthening impact can be quantified as a higher frequency of behavior, a longer duration of behavior, a greater volume of behavior, or a shorter latency.
