BIOL 1408 Unit 1 exam
Biology is the study of - Answer-Living organisms and their interactions with one another and their
environments.
A _______ is a testable suggested explanation for an event. - Answer-hypothesis
What is the difference between a hypothesis and a theory? - Answer-- A theory is a tested and
confirmed explanation for observations or phenomena. - A hypothesis is a testable explanation for an
event.
What is the difference between discovery science and hypothesis-based science? Which one relies more
on inductive reasoning? Deductive reasoning? - Answer-- Discovery science is usually inductive, aims to
observe, explore, and discover. - Hypothesis-based science, which is usually deductive, begins with a
specific question or problem and a potential answer or solution that one can test
What are different variables in a scientific experiment? Identify the correct variable with the description.
Be able to identify these types of variables in an experimental design. - Answer-- Independent Variable -
this is the variable you are changing. - Dependent Variable - this variable depends on the independent
variable. - Control Variable - this variable is the same for all individuals in the study.
_____ science seeks to increase knowledge and may not have a practical application. - Answer-Basic
_____ science aims to solve problems (ex. cure a disease, grow better crops) - Answer-Applied
What are the 7 properties of life? - Answer-- order
- sensitivity/ response to stimuli
, - reproduction,
- growth and development,
- regulation,
- homeostasis,
- energy processing
- evolution
An example of _____________ to stimuli is when an animal uses senses to smell or hear a predator, and
therefore hides or runs. - Answer-sensitivity/response
The _____ is the smallest unit of matter. - Answer-atom
Atoms form ______. - Answer-Molecules
_______ form macromolecules like DNA. - Answer-molecules
Macromolecules form _______. - Answer-organelles
The smallest living unit is the _____. - Answer-cell
Describe the order of living things from simplest to most complex. - Answer-cells, tissue, organ, organ
system, organism, population, community, ecosystem, biosphere.
Describe the following terms: population, biosphere, community, ecosystem. Be able to identify each of
these in an example ecosystem. - Answer-1) Population - all of the individuals of a species living within a
specific area 2) Biosphere - the collection of all the ecosystems on Earth 3) Ecosystem - all the living
things in a particular area together with the abiotic, nonliving parts of that environment
