Answer:
A.
Explanation:
Based on the information provided within the question it can be said that the best option in this scenario for finding the age of these fossils would be to collect a sample of the volcanic ash layers above and below the fossil layer and date the volcanic deposits with Argon dating methods. Such a method would be Potassium-Argon dating in which the product of the radioactive decay of an isotope of potassium (K) into argon (Ar) are compared in order to calculate an estimated age.
Answer:
reactive
Explanation:
Societies who made reactive change only make it in order to adapt Rather than do it for a certain cause or principles.
In the example above, BP's already know that their method of over exploitation could possess a risk for oil spilling, and yet they did not make the necessary effort to prevent it.
After the explosion occurred and the spilled oil damaged the nearby environment, BP decided to make a change by containing surface oil and Utilizing chemical oil dispersal to separate the oil that is spilled underwater.
BP made the change in reaction after the accident occured, not before. Which is why we consider this as a reactive change.
Researchers record the average time it takes rats to complete the maze. In this study, the number of feed pellets was independent as per Manipulation of the Independent Variable
Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis . Instrumental variables are the independent variables in an experiment. It's called "manipulated" because it's something you can change. That is, you can decide in advance whether to increase or decrease. Experiments should always have only one instrumental variable.

Answer:
The correct answer would be option B, Wondered and Wanted to Explore.
Explanation:
Curiosity is something when someone has a strong desire or urge to know about something. So when people have eagerness to know about something, they are said to be curious about that thing. So to show the curiosity, many things play role, like body language of the person who is curios, facial expressions, his words, his accent, anything. There are certain words that are used to detect the curiosity in a person for something. So in this example, Manjiro used the words Wondered and wanted to explore, which show his curiosity about discovering his pockets.
