Let me try: an example of a scientific question that can be investigated with an experiments is "at what temperature does iron melt"?Questions in physics ans chemistry are easily tested with experiments. an example of a scientific question that cannot be (I think) investigated with an experiments is "how does neuron activaton lead to us having the perception of free will"?Questions connected to human mind on a more general lever are not as easily tested with experiments: they need models rather than this.
Answer:
This statement corresponds to the first postulate of the cell theory:
All living things, whether they be unicellular or multicellular, are made up of cells.
Explanation:
The statement indicates the presence of universality in the composition of all living things by stating that cells can be observed in all organisms in the 6 kingdoms of life.
Cell Theory:
Cell Theory is the fundamental principle of biology. It states that:
- All living things are made up of cells, whether they be unicellular or multicellular.
- All cells are produced from pre-existing cells,not from spontaneous generation.
- The cell is the basic functional and structural unit of life.
So they can defend themselves
The organelle in plants when empty causes wilting is the vacuole. A vacuole in plants cells is very large and surrounded by a membrane and holds materials such as nutrients and waste and helps maintain the proper structure of the plant, less liquid in the vacuole can cause wilting.
