BIOL 101 MIDTERM EXAM STUDY GUIDE WITH
QUESTIONS AND CORRECT ANSWERS LATEST
UPDATED RATED A+
The properties of life (characteristics) shared by all living things
reproduction, growth and development, energy use, order, cells,
response to the environment, and evolution.
reproduction
all organisms reproduce their own kind.
growth and development
information carried by genes controls the pattern of growth in all
organisms.
energy use
every organism takes in energy, converts it to useful forms, and expels
energy. Ex. elephant; an elephant is taking in energy by eating a plant. it
can use the energy to move. it also releases energy as heat.
order
each living thing has a complex but well-organized structure.
cells
all living organisms consist of cells. some living organisms have just one
cell, but others have trillions.
response to the environment
,all organisms respond to changes in the environment. many of these
responses help to keep an organism's internal environment within
narrow limits even when the external environment changes a lot. Ex.
elephant: an elephant is responding to the heat of the day by taking a
bath, which helps keep its body temperature steady.
evolution
individuals with traits that help them survive and reproduce pass the
genes for those traits to offspring. over many generations, such
adaptations drive the evolution of populations. Ex. modern elephants
and woolly mammoths evolved from a common ancestor species that
lived until about 5 million years ago.
The levels of biological organization
biosphere, ecosystem, community, population, organism, organ system,
organ, tissue, cell, organelle, molecule, atom
Biosphere
consists of all life on Earth and all of the environments that support of
life, from the deepest oceans to high in the atmosphere.
Ecosystem
includes all the living organisms in one particular area as well as the
nonliving components that affect life, such as soil, air, and sunlight.
Community
consists of all the interacting populations of organisms occupying an
ecosystem. includes plants, animals, and even microscopic organisms.
Population
, a group of interacting individuals of one species.
Organism
an individual living being
Organ System
a group of organs that work together to perform a vital body function.
Organ
consists of multiple tissues that cooperate to perform a specific task. a
part of an organism that is typically self-contained and has a specific
vital function.
Tissue
an integrated group of similar cells that work together to perform a
specific function.
Cell
the fundamental unit of life. the smallest structural and functional unit
of an organism. microscopic and consisting of cytoplasm and a nucleus
enclosed in a membrane.
Organelle
a component of the cell that performs a specific function. within the
cell.
Molecule
a group of atoms bonded together.
Atom
