Exam Questions 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.
Atom -CORRECT ANSWER the fundamental unit of matter. it is the smallest unit of an
element capable of displaying the properties of that element. made up of even smaller
unites called subatomic particles.
Scientific Method -CORRECT ANSWER involving the observation of phenomena, the
formulation of a hypothesis concerning the phenomena, experimentation to demonstrate
the truth of falseness of the hypothesis, and results that validate or modify the
hypothesis.
Scientific Method consists of: -CORRECT ANSWER observation, question, hypothesis,
experiment, results, and conclusion.
hypothesis -CORRECT ANSWER a proposed explanation for an observation. must be
testable, and the results of such tests will either support or refute it.
