An organism that obtains energy and nutrients by feeding on other organisms or their remains. A food web is a model of the feeding relationships between many different consumers and producers in an ecosystem. Without plants (the primary producers) consumers and decomposers would not be able to live. Producers always start every food chain. A consumer, also called a heterotroph, is an organism that cannot make its own food. It must eat producers or other organisms for energy.
I believe the answer you are looking for is they are all body systems found in the human body, or organ systems.
Answer:
Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.
Explanation:
In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.
Answer:
No
Explanation:
A renewable resource is one in which the rate at which its being replenished is higher than the rate at which it is being used up.
For example, the air we breathe is a renewable resource because it doesn't get used up as we draw it.
- If the rate of drawing down a ground water supply exceeds the rate of its recharge, then such a water source is non-renewable.
