What are the 8 characteristics of all living things?
Order/Cells
Regulation
Growth and Development
Metabolism
Response to Environment
Reproduction and DNA
Evolutionary Adaptation
All living things have complex organizations. What is this called?
Order
The living organisms need order to live why?
Living things have complex organization. For example, a single-celled organism is composed of highly organized molecules while multi-cellular organisms have many layers of organization.
True or False:
Something must have all the characteristics of life to be considered alive.
True
What is a localized group of the same species that can interbreed to produce fertile offspring called?
a. individual
b. population
c. community
d. ecosystem
b. population
Which of these categories in the hierarchy of life is the most inclusive?
F. ecosystem
Which of these scenarios demonstrates the biological theme of interaction of organisms with their environment?
A. grasshopper eating a leaf
True or False:
Evolution is the overarching theme of biology.
True
To which domain do humans belong?
C. Eukarya
Which variable is measured during a scientific experiment?
a. independent
b. dependent
c. standardized
d. all of the above
e. none of the above
b. dependent
In an experiment where 100 people are asked to choose their favorite color from a list of 7 different colors, what will the degrees of freedom be for a Chi-square test?
H. 6
True or False:
The independent variable in an experiment may have an effect on the dependent variable.
True
True or False:
If the p-value in a chi-square test is less than 0.05, then we reject the null hypothesis.
True
Living things regulate their internal environments. What is this called?
Regulation
What is regulation?
Living things regulate their internal environments. Maintenance of a relatively stable internal environment in the face of a fluctuating external environments called "homeostasis". For example, humans maintain a fairly constant body temperature of about 98.6° F.
Organisms add mass or "grow" and change the organization of their bodies as they mature or "develop". What is this?
Growth and Development
All living things need energy input for growth, development, and the maintenance of homeostasis
Metabolism
Living things must be able to respond to the environment around them to stay alive
Response to Environment
Reproduction whether sexual or asexual is away to get genes into the next generation
Reproduction and DNA
Natural selection allows species of organisms to be adapted to the environment in which we find them.
EvolutionaryAdaptation
Hierarchy of Life: the entire portion of the earth that is inhabited by life; the sum of all the planet's ecosystems
Biosphere
all of the organisms in a given area and all of the abiotic factors with which they interact; one or more communities and the physical environment around them
Ecosystem
all of the organisms that inhabit a particular area; an assemblage of populations of different species living close enough together for potential interaction
Community
a localized group of individuals of the same species that can interbreed to produce fertile offspring
Population
individual living things
Organism:
a team of organs that cooperates in a specific function
Organ System:
a body part that consists of two or more tissues
Organ:
a group of similar cells; an integrated group of cells with a common function, structure, or both
Tissue:
Life's fundamental unit of structure and function; the fundamental unit of life
Cell:
functional component of a cell
Organelle:
chemical structure composed of two or more atoms
Molecule:
distinguish between eukaryotic and prokaryotic organisms
the difference between prokaryotic organisms from eukaryotic organisms is that prokaryotic organisms do not have a nucleus and eukaryotic organisms do
characterize the domains and kingdoms of life
species, genus, family, order, class, phylum, kingdom, and domain.
What is the unifying theme in biology?
Evolution via natural selection is the core theme that explains the unity and diversity of life on earth. The basic tenets of this theme include:
•Individuals in populations vary.
•Not all offspring produced survive.
•Individuals have unequal success at survival and reproduction.
•Over time, favorable traits accumulate.
