Answer:
they are machines or devices build to find la DNA trace and copy it multiple times.
Explanation:
DNA machines are machines built to find a DNA line and copy it multiple times, so scientists can read, observe, and find information about the DNA strand. For example, DNA machines can determine if someone is related, if someone has cancer, and it can distinguish a person’s ancestry. Mainly this is how forensic science uses to determine when there's a suspect in a crime.
The question is incomplete, however, the statements associated with this question is given in the comments and here as well:
Neither facilitated diffusion nor osmosis requires cell energy.
Diffusion of gases and other small molecules requires no energy on the part of the cell.
Active transport requires cell energy and osmosis doesn't.
Both endocytosis and active transport require cell energy.
Answer:
The correct answer is - Active transport requires cell energy and osmosis doesn't.
Explanation:
Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.
In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.
You would want this observation to be in an area with a lot of biotic and abiotic factors, so the best place for it is an ecosystem.
Answer:
Cell fractionation allows to study the different parts of a cell in isolation.When the organelles have been isolated, you can see which organelles make the most energy.
