A+)
What is biology? - ANSWERThe scientific study of life.
7 characteristics of life? (Properties that we use to define what life is.) - ANSWER1.
Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
7. Growth and Development
Hypothesis vs. theory? - ANSWERHypothesis: 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? - ANSWERAn 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? - ANSWERQuantitative data includes recorded
measurements which can be organized into tables or graphs and qualitative data
would include observations.
Inductive reasoning vs. deductive reasoning? - ANSWERInductive reasoning derives
generalizations from specific cases and deductive reasoning predicts specific
outcomes from general premises.
What is electronegativity? And how does it affect sharing? - ANSWERThe attraction
of a given atom for the electrons of a covalent bond. The more electronegative an
atom, the more strongly is pulls shared electrons toward itself.
What makes a bond non polar? - ANSWERThe atoms share the electron equally.
What are ionic bonds? - ANSWERAn attrition between an anion and a cation. They
are transferred.
, What are ions? - ANSWERA charged atom (or molecule). The atom will strip the
election. An example is the transfer of an electron form sodium to chlorine.
What is an element? - ANSWERAny substance that cannot be broken down to any
other substance by chemical reactions.
What is a compound? - ANSWERA thing that is composed of two or more separate
elements; a mixture.
Characteristics of an element? - ANSWERAtoms 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? - ANSWERCompounds 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? - ANSWERCarbon,
oxygen, hydrogen, and nitrogen.
What are trace elements? - ANSWERThose required by an organism in minute
quantities.
Name the 3 major subatomic particles. - ANSWERNeutrons (no charge)
Protons (+)
Electrons (-)
Where are the protons and neutrons located? - ANSWERIn the atomic nucleus.
Forms cloud around the nucleus. - ANSWERElectrons.
What number defines the element? - ANSWERMass number
What unit are subatomic particles measured in? - ANSWERDaltons.
What does the atomic number represent? - ANSWERNumber of protons in nucleus.
What values can we discern from the mass number? - ANSWERSum of protons +
neutrons in the nucleus.
What is an isotope? - ANSWER2 atoms of an element that differ in number of
neutrons.
How do you know when 2 atoms are isotopes? What number is different? -
ANSWERThey differ in numbers of neutrons and the mass number is different.
