BIO 110 HUMAN BIOLOGY QUESTIONS AND ANSWERS | COMPLETE
HUMAN BIOLOGY STUDY GUIDE 2026/2027
Define Biology - ✔✔the study of living things
Identify and explain the major characteristics of life. Be able to recognize an example of each. -
✔✔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 - ✔✔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 - ✔✔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 - ✔✔atom, molecule,
organelle, cell, tissue, organ, organ system, organism
Differentiate between a hypothesis, prediction, and theory - ✔✔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.
- ✔✔Definition of homeostasis- ability to maintain a relatively constant internal environment.
The nervous system and endocrine system are key in maintaining homeostasis.
Understand how negative feedback loops control and maintain homeostasis. - ✔✔Negative feedback
loops is the output of the system revolves or corrects the original stimulus. It's the primary mechanism.
Three components- sensor, control center, effector.
Identify all 11 organ systems and their basic function - ✔✔Skelton- provides support and protection,
stores minerals, produces red blood cells- Organ- bone
Muscular- assists in movement, produces heat Organs- muscles
