Can organisms create their own energy? Explain your answer
leva [86]
<span>NO
In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web.  </span>

Does the scientific method steps always have to be in the same order? If not, why?
Ierofanga [76]

Answer: The steps may not always be completed in the same order. Following the four steps, the results of the experiment will either support the hypothesis or will not support the hypothesis. Scientists are always free to change or write a new hypothesis and start the four steps all over again.

I really hope that helps

Answer:

The answer to these questions are the following:

1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter

2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter

Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:

1. In a hypotonic solution, the cells will become turgid  

2. In an isotonic solution, the cells will become flaccid.  

3. In a hypertonic solution, the cells will shrink (plasmolysis)

When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss

When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.
