Whose theory of evolution believes that every organism has an internal vital force?
1 De Vries theory
2 Lamarckism
3 Darwinism
4 Weismann theory
Explanation:

"Frequency of resistant viruses increases in population by using medication". Which of the following options is/are correct explaining the above statement?
1 Nature favours those characteristics which provide advantage in the current environment
2 Drugs create resistant pathogens
3 Nature selects resistant individuals that are already present in populations and survived.
4 Both (1) and (3)
Explanation:
This is according to use and disuse theory, i.e., if a organ is used more often then it gets stronger. The person who does the work in fields and hold the sickles etc in the hand, for them the epidermis on palm becomes thicker.

Survival of the fittest is possible due to the
1 Production of the best species
2 Adaptive ability which is genetic in origin
3 Adaptive ability which is non- genetic in origin
4 Inheritance of acquired characters
Explanation:
When favorable variations came in the environment and one species is more fitted to that change then that \(\&\) species will be more fitted to environment and in successive generation that character transfers and it became main character of the species.
