1.What are the 7 Characteristics of Life? - ANSWER 1. Order
2. Regulation
3. Energy Processing
4. Evolutionary Adaptation
5. Response to the Environment
6. Reproduction
7. Growth and Development
2.Chromatids remain attached to one another until anaphase. - ANSWER 1) The
centromere is a region in which
A) chromatids remain attached to one another until anaphase.
B) metaphase chromosomes become aligned at the metaphase plate.
C) chromosomes are grouped during telophase.
D) the nucleus is located prior to mitosis.
E) new spindle microtubules form at either end.
3.Evolution - ANSWER Evolution is the process of change that has transformed
life on Earth
4. DNA - ANSWER Deoxyribonucleic acid: a long linear polymer found in the
nucleus of a cell and formed from nucleotides and shaped like a double helix
5. Emergent properties - ANSWER New properties that arise with each step
upward in the hierarchy of life, owing to the arrangement and interactions of parts
as complexity increases.
6.Eukaryotic Cell - ANSWER A type of cell with a membrane-enclosed nucleus
and membrane-enclosed organelles. Organisms with eukaryotic cells (protists,
plants, fungi, and animals) are called eukaryotes.
, 7.Prokaryotic Cell - ANSWER A type of cell lacking a membrane-enclosed
nucleus and membrane-enclosed organelles. Organisms with prokaryotic cells
(bacteria and archaea) are called prokaryotes.
8.Gene - ANSWER A discrete unit of hereditary information consisting of a
specific nucleotide sequence in DNA (or RNA, in some viruses).
9.Gene expression - ANSWER The process by which information encoded in
DNA directs the synthesis of proteins or, in some cases, RNAs that are not
translated into proteins and instead function as RNAs.
10. Genome - ANSWER The genetic material of an organism or virus; the
complete complement of an organism's or virus's genes along with its noncoding
nucleic acid sequences.
11. Biosphere - ANSWER The entire portion of Earth inhabited by life; the sum of
all the planet's ecosystems.
12. Ecosystems - ANSWER All the organisms in a given area as well as the abiotic
factors with which they interact; one or more communities and the physical
environment around them
13. Community - ANSWER All the organisms that inhabit a particular area; an
assemblage of populations of different species living close enough together for
potential interaction.
14. Population - ANSWER A group of individuals of the same species that live in
the same area and interbreed, producing fertile offspring.
15. Organism - ANSWER a creature such as a plant, animal or a single-celled life
form, or something that has interdependent parts and that is being compared to a
living creature
16.Organs - ANSWER A specialized center of body function composed of several
different types of tissues.
17. Organ Systems - ANSWER A group of organs that work together in
performing vital body functions.
, 18.Tissues - ANSWER An integrated group of cells with a common structure,
function, or both. Ex. muscle or nervous
19. Organelles - ANSWER Any of several membrane-enclosed structures with
specialized functions, suspended in the cytosol of eukaryotic cells.
molecules that are arranged into minute structures, crucial functional components
of cells (cellulose, plasma membrane)
20. Molecule - ANSWER Two or more atoms held together by covalent bonds.
21. Negative Feedback - ANSWER A form of regulation in which accumulation of
an end product of a process slows the process; in physiology, a primary mechanism
of homeostasis, whereby a change in a variable triggers a response that counteracts
the initial change.
22. Positive Feedback - ANSWER A form of regulation in which an end product of
a process speeds up that process; in physiology, a control mechanism in which a
change in a variable triggers a response that reinforces or amplifies the change.
23.Adaptation - ANSWER Inherited characteristic of an organism that enhances
its survival and reproduction in a specific environment.
24. Inductive Reasoning - ANSWER Induction moves from a set of specific
observations (humans require organic molecules, fish require organic molecules) to
reach a general conclusion (all animals require organic molecules
25. Data - ANSWER Recorded observations.
26. Hypothesis - ANSWER 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.
27. Deductive Reasoning - ANSWER A type of logic in which specific results are
predicted from a general premise.
28. Controlled Experiment - ANSWER An experiment in which an experimental
group is compared with a control group that varies only in the factor being tested.
29. Dependent Variable - ANSWER It is something that depends on other factors.
, 30. Independent Variable - ANSWER It is a variable that stands alone and isn't
changed by the other variables you are trying to measure.
31. Theory - ANSWER An explanation that is broader in scope than a hypothesis,
generates new hypotheses, and is supported by a large body of evidence.
32. Metabolism - ANSWER The totality of an organism's chemical reactions,
consisting of catabolic and anabolic pathways, which manage the material and
energy resources of the organism.
33. Why is Biology a Science? - ANSWER Biology is a science since it takes care
to interpret the nature, according to the scientific method, which establishes the
resolution of hypotheses raised by the researcher, by means of using different
techniques for the creation of representative models of nature.
34. Distinguish between Inductive and Deductive Reasoning - ANSWER Inductive
reasoning derives generalizations from specific cases and deductive reasoning
predicts specific outcomes from general premises.
35. What are the 7 steps of the Scientific Method? - ANSWER 1. Observe
2. Research
3. Form a hypothesis
4. Test the hypothesis
5. Analyze results and draw conclusions
6. Report your findings
7. Conduct more research
36.What is the difference between hypothesis, theory and law? - ANSWER The
Difference between a Hypothesis a Theory and a Law there are very distinct. A
hypothesis is a statement that can be tested. A theory is a statement that has not
been tested. A Law is a statement that is relevant and is true.
37. What is the difference between observational and experimental investigations?
- ANSWER Observational investigations do not manipulate data
38.What is the difference between qualitative and quantitative data? - ANSWER
Quantitative data includes recorded measurements which can be organized into
tables or graphs and qualitative data would include observations
