2. Conceptual models: ties together many ideas to explain a phenomenon or event.
3. Mathematical models: sets of equations that take into account many factors to represent a phenomenon. Mathematical models are often done on computers.
4. Mental models: personal and internal representations of external reality that people use to interact with the world around them. They are constructed by individuals based on their unique life experiences, perceptions, and understandings of the world.
Answer:
The use of heat to burn foodstuffs
The use of chemical energy to transport organelles through the cytosol
Explanation:
In plant cells, sunlight energy is converted into chemical energy in a process known as photosynthesis which happens in the chloroplast.
During respiration, cells generally metabolize nutrients to produce useful energy in the form of ATP.
<em>Heat is not used to burn foodstuffs in any cell while organelles are not transported through the cytosol in any cell.</em>
The answer is B, because only plants have chloroplasts (which they use for photosynthesis) and cell walls (which protects and supports the plant cell)
