Answer:
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.
B!!!! Relative dating utilizes laws like the law of superposition for age determination
Answer:
B
Explanation:
While humans have the same genome, there bear very minute differences (0.01%) between individuals that make them different from one another. The closer you are in a hereditary relationship, the lower this difference. This difference can be used to determine the genetic relationship and is called a DNA fingerprint.
It involves cutting up DNA from a sample using restrictions enzymes and then running the sample on an electrophoresis gel. The resulting bands are compared between two individuals. The more the bands align, especially at regions where people differ alot such as Short Tandem Repeat regions, the higher the genetic relationship between the two.
