Answer:
Explanation: ground water contamination is nearly
always the result of human activity. In
areas where population density is high and human
use of the land is intensive, ground water is especially vulnerable. Virtually any activity whereby
chemicals or wastes may be released to the environment, either intentionally or accidentally, has
the potential to pollute ground water. When
ground water becomes contaminated, it is difficult
and expensive to clean up.
To begin to address pollution prevention or remediation, we must understand how surface waters
and ground waters interrelate.
Answer: Non-falsifiable hypotheses: Hypotheses that are inherently impossible to falsify, either because of technical limitations or because of subjectivity. E.g. "Chocolate is always better than vanilla." [subjective].
A statement, hypothesis, or theory has falsifiability if it can be proven false by contradicting it with a basic statement or observation.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!!!!!!!! :D
Explanation:
The correct answer for this question is C - the best description of a
chemical reaction from the answers offered here is that it consists of
the forming and breaking of bonds between particles. There are not any
atoms destroyed in a chemical reaction, so B and C are incorrect, and
although mixing two substances together (as specified in A) could
produce a chemical reaction, this is not the best way of describing the
actual chemical process.
Answer:
Hypothesis, controlled conditions, "if then" statement, scientific investigation, observation.
Explanation:
Hypothesis: An idea proposed for an argument to be tested if it's true.
Controlled Conditions: An experiment that doesn't manipulate the independent variable.
If then statements: These sentences present situations and their outcomes.
Scientific Investigation: A plan for asking questions and testing possible answers.
Observation: Using one of the senses (hearing, seeing, tasting, smell, touching) or measurements to gather data.
