Organism: Any living thing that takes in food, grows, and reproduces.
Answer:
All are true of the movement of Earth's atmosphere except :
d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.
Explanation:
- When gases heat up, their volume increases and density decrease.
- A decrease in density causes a substance to become lighter.
- Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
- So, it will move up.
- The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
- Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
The statements of the old cell theory are:
1. All organisms are composed of cells
2. The cell is the basic unit of life
3. Cells are produced from existing cells
The modern cell theory's statements are:
1. The cell contains hereditary information which is passed to daughter cells
2. All cells are basically the same in composition and activity
3. All basic functions occur in cells
4. Cell activities depend on intracellular structures
As is visible from the statements, the old cell theory was not as detailed and lacked the understanding of the function, structure and behavior of cells that the current theory possesses. This difference has come about after years of research, through which scientists understood the functions of cells and elaborated on the theory's statements.
