Fundamentals of Animal Biology Flashcards
The scientific study of animal life
Zoology
What is the nature of science
Gaining knowledge using the scientific method
The process of objectively establishing facts through testing and experimentation.
Scientific Method
What are the four (4) main steps in the scientific method
- Observation
- Hypothesis
- Experimentation
- Conclusion
What does chemical uniqueness mean?
Living systems demonstrate a unique and complex molecular organization.
What are the four (4) major categories of macromolecules?
- Nucleic Acids
- Proteins
- Carbohydrates
- Lipids
What are the seven (7) general properties of living systems?
- Chemical Uniqueness
- Complexity and hierarchical organization
- Reproduction
- Possession of a genetic program

Living systems can reproduce themselves
Reproduction
What are the two types of reproduction?
Asexual and Sexual
transmission of traits
heredity
differences in traits
variation
a genetic program provides a fidelity of inheritance
possession of a genetic program
Where can genetic information be found?
DNA
Who discovered that DNA is a double helix?
James Watson and Francis Crick
Nucleotide base sequence order of amino acids
genetic code
Living organisms maintain themselves by obtaining nutrients from their environments
Metabolism
Study of performance of complex metabolic functions
physiology
All organisms pass through a characteristic life cycle
Development
Characteristic changes that an organism undergoes
zygote to adult senescence
All animals interact with their environment
Environmental interaction
permits to understand how an organism can perceive environmental stimuli and respond in appropriate ways by adjusting its metabolism and physiology
Ecology
Any eukaryotic organism that is not plant, animal, or fungus.
Protists
How many amino acids are found in protein?
20 amino acids
What are the eight (8) levels of taxonomy?
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Other term for sex cells
Gametes
How do bacteria reproduce?
Through binary fission
What is the best trait in surviving?
Reproduction
How do the cells in the body differ if they have the same DNA?
They have different active genes.
