Zoology correct answers The scientific study of animal life
General Properties of Living Systems correct answers Chemical uniqueness; complexity
and hierarchical organization; reproduction; possession of a genetic program;
metabolism; development; environmental interaction; movement
Chemical uniqueness correct answers Living systems demonstrate a unique and
complex molecular organization
small molecules are assembled into macromolecules correct answers 1. nucleic acid
2. proteins
3. carbohydrates
4. lipids
Complexity and Hierarchical Organization correct answers Living systems demonstrate
a unique and complex hierarchical organization
In living systems there exists a hierarchy of levels that includes: correct answers
Macromolecules
cells
organisms
populations
species
Reproduction correct answers Living systems can reproduce themselves
At each level of the biological hierarchy living forms reproduce to generate others like
themselves correct answers Genes, cells, organisms, populations, species
Genes correct answers replicate to produce new genes
Cells correct answers divide producing new cells
Organisms correct answers reproduce, sexually or asexually, to produce new
organisms
Populations correct answers fragment to produce new populations
Species correct answers split to produce new species
Possession of a Genetic Program correct answers A genetic program provides fidelity of
inheritance
, nucleic acids correct answers encode structures of the protein molecules needed for
organismal development and functioning
DNA correct answers Stores genetic information: long, linear, chain of nucleotides
genetic code correct answers correspondence between base sequences in DNA and
the sequence of amino acids in a protein
Metabolism correct answers Living organisms maintain themselves by acquiring
nutrients from their environments
metabolic processes include: correct answers digestion
energy production (respiration)
synthesis of required molecules and structures by organisms
Development correct answers All organisms pass through a characteristic life cycle
development describes correct answers the characteristic changes that an organism
undergoes from its origin to its final adult form
Environmental Interaction correct answers All animals interact with their environments
ecology correct answers the study of organismal interaction with an environment
irritability correct answers all organisms respond to environmental stimuli
Movement correct answers Living systems show precise and controlled movements
from within the system; living systems extract energy from the environment allowing
controlled movement
movements at cellular level required for: correct answers reproduction; growth;
response to stimuli, development in multicellular organisms
On a larger scale correct answers entire populations or species may disperse from one
geographic location to another over time
movement of nonliving matter correct answers not precisely controlled by moving
objects and often involves external forces
First Law of Thermodynamics correct answers the law of conservation of energy;
energy is neither created nor destroyed but can be transformed from one to another
Second Law of Thermodynamics correct answers physical systems tend to proceed
toward a state of greater disorder, or entropy
