Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.
In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.
These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.
Answer:
1. Cell
2. cell theory
3. Organismal theory
4. resolving power
Explanation:
The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).
2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.
It states:
1. Living organisms are made up of cells.
2. Cells are the basic unit of life.
3. Cells are formed from pre-existing cells.
4. Energy flows inside the cell.
5. DNA is passed on from cell to cell.
6. All cells have the same basic chemical composition.
3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.
4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
