BIO 1050 FINAL EXAM QUESTIONS
AND ANSWERS
Science - Correct Answers -the intellectual and practical activity encompassing the
systematic study of the structure and behavior of the physical and natural world through
observation and experiment.
Biology - Correct Answers -The study of life
Hypothesis - Correct Answers -a supposition or proposed explanation made on the
basis of limited evidence as a starting point for further investigation
Theory - Correct Answers -a supposition or a system of ideas intended to explain
something, especially one based on general principles independent of the thing to be
explained
Controls - Correct Answers -the group in an experiment or study that does not receive
treatment by the researchers and is then used as a benchmark to measure how the
other tested subjects do.
Independent Variable - Correct Answers -An independent variable is the variable that is
changed or controlled in a scientific experiment to test the effects on the dependent
variable.
Dependent Variable - Correct Answers -the variable being tested and measured in a
scientific experiment.
Food Chains - Correct Answers -A feeding hierarchy in which organisms in an
ecosystem are grouped into trophic levels and are shown in a succession to represent
the flow of food energy and the feeding relationships between them
Competition - Correct Answers -an interaction between organisms or species in which
both the organisms or species are harmed
Predation - Correct Answers -A form of symbiotic relationship between two organisms of
unlike species in which one of them acts as predator that captures and feeds on the
other organism that serves as the prey.
Sample Size - Correct Answers -the act of choosing the number of observations or
replicates to include in a statistical sample
, Food Quantity - Correct Answers -The amount of food that is being measured
Carbohydrates - Correct Answers -any of a large group of organic compounds occurring
in foods and living tissues and including sugars, starch, and cellulose
Cells - Correct Answers -collection of living matter enclosed by a barrier that separates
the cell from its surrondings, basic uniforms of life.
Eukaryotic Cells - Correct Answers -An organism whose cells contain a nucleus
surrounded by a membrane and whose DNA is bound together by proteins into
chromosomes
Prokaryotic Cells - Correct Answers -a cell that lacks a nucleus and other membrane
bound organelles; includes achaea and bacteria
Functions of Organelles - Correct Answers -https://quizlet.com/410483/cell-organelles-
and-their-functions-flash-cards/
DNA - Correct Answers -deoxyribonucleic acid, a self-replicating material present in
nearly all living organisms as the main constituent of chromosomes. It is the carrier of
genetic information.
RNA - Correct Answers -ribonucleic acid, a nucleic acid present in all living cells. Its
principal role is to act as a messenger carrying instructions from DNA for controlling the
synthesis of proteins, although in some viruses RNA rather than DNA carries the
genetic information.
Translation - Correct Answers -a step in protein biosynthesis wherein the genetic code
carried by mRNA is decoded to produce the specific sequence of amino acids in a
polypeptide chain
Transcription - Correct Answers -the process by which the information in a strand of
DNA is copied into a new molecule of messenger RNA
Cell Division in Eukaryotic Cells - Correct Answers -the cell cycle is divided in
Interphase, where the cell readies itself for division, and Mitosis, where the process of
division occurs. Interphase takes up the majority of the cell cycle. Meiosis can
sometimes occur instead of Mitosis.
Causes of Cancer - Correct Answers -Smoking and Tobacco.
Diet and Physical Activity.
Sun and Other Types of Radiation.
Viruses and Other Infections
Benign - Correct Answers -not harmful in effect:
