mafiozo [28]

Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.

Roman55 [17]

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.
