Antonie van Leeuwenhoek viewed moving objects from pond water under his microscope and named them “animalcules.
Antonie van Leeuwenhoek was a scientist and the first microscopist to observe protozoa and bacteria. He created microscopes that possess a single high-quality lens of small focal length and isolated tiny animalcules (microbes) from various sources such as pond water, well water and rain water. Through his experiments, he also calculated the sizes of the animalcules.
Biological evolution is the process through which the characteristic of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations".

Answer: Option A
Explanation:
Epilepsy can be defined as the medical condition in which the central nervous system disorder in which the brain activity becomes abnormal which results in the abnormal behavior, sensation accompanied by loss of awareness.
In this condition a drug that can best treat epilepsy should reduce the activity of neurons in the epileptic focus which are excitatory neurons based on the effect throughout their cortex.
It does so by increasing the threshold which is required to generate action potential which will decrease the chances that neurons will fire.
This effect will reduce the overall amount of excitation which spreads from epileptic focus throughout the cortex.
hence, the correct answer is option A
<span>The answer is binary fission. Binary fission is a type of cell division characteristic for unicellular organisms, such as protozoans. This type of cell division includes: 1. duplication of genetic material, cell growth, the formation of the cell membrane, and simple separation of the cell into two new cells.</span>
