BIOD 101 - Exam 2 Questions with Correct
Answers
List the 7 most widely accepted characteristics of living organisms.: - CORRECT ANSWER -
1.) Order
2.) Evolutionary Adaptation
3.) Regulation
4.) Energy Processing
5.) Growth and Development
6.) Response to the Environment
7.) Reproduction
What is ORDER? - CORRECT ANSWER -
Highly ordered structures are comprised of the basic unit of life which is the cell
What is EVOLUTIONARY ADAPTATION? (Give an example) - CORRECT ANSWER -
Smaller genetic changes that allow for better survival of an organism; an example of evolutionar
y adaptation is camouflage, animals that are camouflaged within their given environment will, t
heoretically, live longer and will thus reproduce more.
What is REGULATION? (Give an example) - CORRECT ANSWER -
Regulation is the ability of an organism to handle changes within their internal and external envi
ronment so that they can maintain homeostasis (a state of balance internally that is needed for
the body to survive and function correctly); An example of regulation is when humans shiver to
generate body heat.
What is ENERGY PROCESSING? (Give an example) - CORRECT ANSWER -
When biochemical reactions are utilized to produce energy (also known as metabolism); an exa
mple is photosynthesis in plants, or when an animal ingests food.
, Define GROWTH AND DEVELOPMENT: - CORRECT ANSWER -
When a living thing grows, matures, ages, and experiences death.
Define RESPONSE TO THE ENVIRONMENT: - CORRECT ANSWER -
When living things respond to a stimulus within their environment through adaptation.
Define ADAPTATION: (Give an example) - CORRECT ANSWER -
Adaptation is a change or process that allows an organism to become better suited for their envi
ronment; Adaptations can be physical or behavioral -
an example of a physical adaptation is a crab's hard shell, an example of a behavioral adaptatio
n is when a bear hibernates through the winter.
What is REPRODUCTION? List the two different types of reproduction. - CORRECT ANSWER -
Reproduction is when a new generation of offspring are produced; the two types of reproductio
n are sexual or asexual.
What is SEXUAL REPRODUCTION? - CORRECT ANSWER -
Sexual reproduction involves the fusion of two gametes (one from each parent) that will unite a
nd grow into a new offspring.
What is ASEXUAL REPRODUCTION? - CORRECT ANSWER -
Asexual reproduction gives rise to new offspringBfrom a single organism.
What are the levels of BIOLOGICAL ORGANIZATION? - CORRECT ANSWER -
Biological Organization are successive levels of structure that go broadest to smallest, the levels
are:
- Biosphere
- Ecosystem
- Communities
