BIO 100 FINAL EXAM | QUESTIONS AND ANSWERS | VERIFIED
ANSWERS GRADED A+ | LATEST EXAM
Biology - CORRECT ANSWER - the study of living organisms and how they
interact with their environment
Ways of Studying Living Organisms - CORRECT ANSWER - 1.
Philosophical
2. Scientifically
a. through observation
b. asking questions
c. doing experiments
d. looking at results
Levels of Life (Big to Small) - CORRECT ANSWER - 1. Biosphere
2. Ecosystems
3. Communities
4. Populations
5. Organisms
Biosphere - CORRECT ANSWER - everything on earth that has living
organisms
Ecosystems - CORRECT ANSWER - area of a defined environment with a
certain collection of organisms
,Communities - CORRECT ANSWER - a group or organisms within the
environment interacting with each other and the environment; consists of 2 or
more species
Populations - CORRECT ANSWER - group of organisms living within the
bounds of a specified area
Organisms - CORRECT ANSWER - Individual living things
Aspects of Living Organisms - CORRECT ANSWER - 1. Order
2. Regulation
3. Energy Processing
4. Growth and Development
5.Reproduction
6. Response to the Environment
7. Evolutionary Adaption
Themes of Biology - CORRECT ANSWER - 1. Evolution
2. Cell Theory
3. Genetics
4. Homeostasis
Evolution - CORRECT ANSWER - - Makes sense of everything we know
about living organisms
- organisms living on earth are modified based on change at DNA level
- DNA changes randomly through mutation
- Mutations are always occurring
- Selective mutation - selects changes
- Organisms that survive adapt mutations that are seen in the next generation
,Cell Theory - CORRECT ANSWER - - The cell is the lowest level of
organization that can perform activities required for life
All cells:
- membranes
- DNA
Genetics - CORRECT ANSWER - - Chromosomes contain most of cells'
genetic matter in the form of DNA
- DNA is the substance of genes
- Chromosomes are the unit of inheritance that transmit information from
parents to the offspring
Homeostasis and Behavior - CORRECT ANSWER - - Every organism has
systems to maintain a constant internal environment regardless of external
conditions
- Every organism interacts with its environment, including nonliving factors and
other organisms
- Both, organisms and their environment, are affected by the interactions
between them
Ecosystem Dynamics - CORRECT ANSWER - 2 processes:
- cycling of nutrients in which materials acquired by plants eventually return to
the soil
- the flow of energy from sunlight to producers to consumers
Grouping Species - CORRECT ANSWER - - Taxonomy is the branch of
biology that names and classifies species into groups of increasing breadth
- Domains, followed by Kingdoms, are the broadest units of classification
, The Three Domains of Life - CORRECT ANSWER - - a system currently used
that replaces the five-kingdom system
- Domain Bacteria and Domain Archaea comprise the prokaryotes
- Domain Eukarya includes all the eukaryotic organisms
What factors are involved in determining populations size? - CORRECT
ANSWER - - Resources
- Space
- Type of niche/ecosystem
- Speed of reproduction
- Death rate
- Immigration/Emmigration
Why is a population size critical? - CORRECT ANSWER - - it is determined
by carrying capacity
rich -- high population
low - population
Carrying Capacity - CORRECT ANSWER - amount of organisms an
environment can support
Factors that influence Carrying Capacity - CORRECT ANSWER - - food
- space
- predation
- resources
- water
- immigration --> organisms entering population
- emigration --> organisms leaving population
