Think about redi's experiment described above. it was one step in building cell theory. what aspect of cell theory did redi's experiment support?
a) all cells come from pre-existing cells.
b) cells are the smallest and most basic unit of life.
c) all living things are composed of one or more cells.
d) the cell is the functional unit of all living things.

A. All cells come from pre-existing cells

Explanation:

Francesco Redi's experiments aimed to test spontaneous generation, where life could emerge from non-living things. His first round included two groups of jars with raw meat in it. He covered one group with a thin cloth, allowing only air to get in, and the other group was left open.

In the jars left open, he noted maggots were present and the one that was covered contained no maggots.

The results indicated that the maggots only formed because flies laid their eggs on it and maggots developed. He did note that some maggots developed on the cloth itself, but on the outside.

Thus, he contributed in disproving spontaneous generation by showing that maggots only developed from the eggs that flies laid. This supports that all cells come from pre-existing cells.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
