and Answers Graded A+
The properties of life (characteristics) shared by all living things - Correct answer-
reproduction, growth and development, energy use, order, cells, response to the
environment, and evolution.
reproduction - Correct answer-all organisms reproduce their own kind.
growth and development - Correct answer-information carried by genes controls
the pattern of growth in all organisms.
energy use - Correct answer-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 - Correct answer-each living thing has a complex but well-organized
structure.
cells - Correct answer-all living organisms consist of cells. some living organisms
have just one cell, but others have trillions.

,response to the environment - Correct answer-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 - Correct answer-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 - Correct answer-biosphere, ecosystem,
community, population, organism, organ system, organ, tissue, cell, organelle,
molecule, atom
Biosphere - Correct answer-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 - Correct answer-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 - Correct answer-consists of all the interacting populations of
organisms occupying an ecosystem. includes plants, animals, and even microscopic
organisms.
Population - Correct answer-a group of interacting individuals of one species.
Organism - Correct answer-an individual living being
Organ System - Correct answer-a group of organs that work together to perform a
vital body function.
Organ - Correct answer-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 - Correct answer-an integrated group of similar cells that work together to
perform a specific function.
Cell - Correct answer-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 - Correct answer-a component of the cell that performs a specific
function. within the cell.
Molecule - Correct answer-a group of atoms bonded together.
