Controlled Investigation
Field Investigation
Explanation: In a controlled experiment, the scientist has total control over the environmental conditions. The temperature, humidity, amount of light, amount of noise, materials, etc. can all be controlled and monitored by the scientist throughout the investigation.
A field investigation involves observing and measuring plants and animals (including people) in their natural habitat or environment without changing, harming, or altering the setting or any part of the test subjects. Like in a controlled experiment, the scientist chooses to observe and measure how one change (IV) has a measurable effect (DV) on something else.
Herbivory, having animals develop to eat plants is an <span>occurrence that represents an example of evolution.</span>
To prevent cells from either shrinking or swelling you should keep them in an isotonic solution. Isotonic solution is a solution with equal amount of solute and solvent. Therefore, when cells are placed in such a solution they will not lose or gain water, as opposed to hypertonic (more solute than solvent) and hypotonic (more solvent than solute) solutions.
