Answer 1

D. The lack of evolution in pathogens


An imbalance from homeostasis perspective is considered to be a disease. Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.

Answer 2

The correct answer is option B. The overuse of antibiotics.

Now-a-days use of antibiotics is very common. The antibiotic is used to kill the disease causing pathogen, but the overuse and the senseless use of the antibiotics cause the pathogen to develop antibiotic resistance. once, the antibiotic resistance is developed, the infection cannot be cured by that antibiotic, which is the main cause of increase in the diseases in society.
