BIO 110 HUMAN BIOLOGY EXAM
QUESTIONS AND ANSWERS
Define Biology - Correct Answers -the study of living things
Identify and explain the major characteristics of life. Be able to recognize an example of
each. - Correct Answers -Major characteristics of life
* cells- collection of living matter. Smallest unit of life
* genetic material- features carried by DNA pass through reproduction
* maintain homeostasis- maintaining an internal balance
* respond to internal and external stimuli- react to changes in environment (temp,
humidity, light and gravity)
* reproduction- organisms make new organisms
* evolution/adaption- change of a closely related group of organisms over time
* Metabolism- require matter and energy to function
* Growth and development- grow in size. Develop organism changes over the course of
its life
Explain the scientific method and its application to the study of environmental problems
- Correct Answers -The scientific method is a process of observation, hypothesis
generation, data collection, analysis of results, and dissemination of findings. Repetition
of measurements or experiments is critical if one is to determine the validity of findings.
Hypotheses are tested and often modified before being accepted.
Describe the placebo effect - Correct Answers -the effect causes people to believe that
they are being effected, but the pill is a dummy pill
List the levels of biological organization from the simplest to most complex - Correct
Answers -atom, molecule, organelle, cell, tissue, organ, organ system, organism
Differentiate between a hypothesis, prediction, and theory - Correct Answers -
Hypothesis- testable statement to explain the observation (inductive reasoning)
Prediction- expected outcome based on knowledge of the factors.
Theory- accepted explanations for how the world works. (Theories have been supported
by so many observations and experiments)
Understand the definition of homeostasis and which organ/body systems work to
maintain homeostasis. - Correct Answers -Definition of homeostasis- ability to maintain
a relatively constant internal environment.
The nervous system and endocrine system are key in maintaining homeostasis.
