◉ 7 characteristics of life? (Properties that we use to define what life
is.)
Answer: 1. Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
7. Growth and Development
◉ Hypothesis vs. theory?
Answer: Hypothesis: A testable explanation for a set of observations
based on the available data and guided by inductive reasoning. A
hypothesis is narrower in scope than a theory.
Theory: An explanation that is broader in scope than a hypothesis,
generates new hypotheses, and is supported by a large body of
evidence.
,◉ What is a controlled experiment?
Answer: An experiment in which an experimental group is
compared with a control group that varies only in the factor being
tested.
◉ What makes a good hypothesis?
Answer: ...
◉ How many variables can you test at once?
Answer: ...
◉ Quantitative vs. Qualitative data?
Answer: Quantitative data includes recorded measurements which
can be organized into tables or graphs and qualitative data would
include observations.
◉ Inductive reasoning vs. deductive reasoning?
Answer: Inductive reasoning derives generalizations from specific
cases and deductive reasoning predicts specific outcomes from
general premises.
◉ What is an element?
Answer: Any substance that cannot be broken down to any other
substance by chemical reactions.
, ◉ What is a compound?
Answer: A thing that is composed of two or more separate elements;
a mixture.
◉ Characteristics of an element?
Answer: Atoms cannot be created or destroyed. The elements can be
divided into three categories that have characteristic properties:
metals, nonmetals, and semimetals.
◉ Characteristics of a compound?
Answer: Compounds can be broken back into elements by chemical
reaction, exposure to light, etc. The mass of the compound is
determined by the mass of the elements that made it up. Compounds
cannot be separated by physical means: using magnet, filtration, etc.
When compounds are formed heat and light is given out or
absorbed.
◉ Which 4 elements make up the vast majority of the human body?
Answer: Carbon, oxygen, hydrogen, and nitrogen.
◉ What are trace elements?
Answer: Those required by an organism in minute quantities.
