Life Science Exam Questions Correctly
Answered.
the tendency of a cell to maintain a stable internal environment. - CORRECT ANSWER Homeostasis
refers to
perform certain physiological functions. - CORRECT ANSWER In order for a living organism to sustain its
life, it must be able to
control - CORRECT ANSWER The nervous system is the major ______ system of the body.
cells → tissues → organs → organ systems → organism - CORRECT ANSWER Atoms are the most basic
unit of matter. Two or more atoms from the same or different elements can combine to form molecules.
Cells are the most basic unit of life. Cells are made up of many different types of molecules. Which of the
following accurately shows higher levels of organization within organisms, from least complex to most
complex?
circulatory - CORRECT ANSWER The main purpose of the ______ system is to distribute blood
throughout the body.
All living organisms share certain characteristics. - CORRECT ANSWER All living organisms have complex
organization, they are able to grow and develop, they are able to reproduce and pass on genetic
information to their offspring, they are able to acquire and release energy, and they are able to maintain
stable internal environments.
Which of the following statements can be inferred from the above information?
to break down food into smaller particles - CORRECT ANSWER What is the main function of the digestive
system?
, provide oxygen to the body and eliminate carbon dioxide from the body. - CORRECT ANSWER The major
function of the respiratory system is to:
a group of similar cells that perform a common function - CORRECT ANSWER In a living organism, what is
a tissue?
The cells must be able to reproduce - CORRECT ANSWER Cells are the basic unit of life. Thus, cells are
responsible for maintaining a stable internal environment within living organisms.
How do humans continue to maintain a stable internal environment if billions of cells die within their
bodies each day?
all cells must come from pre-existing cells. - CORRECT ANSWER In 1862, a French chemist named Louis
Pasteur performed the following experiment.
Pasteur placed broth in a special type of flask that allowed air to enter and exit. Then, he heated the
broth and flask, so they no longer contained any bacterial cells. Finally, after observing the flask for a
few days and noticing that nothing grew in the flask, he was able to conclude that
Cell A performs all of the organism's necessary functions, while cell B performs only one or a few
functions. - CORRECT ANSWER A scientist is comparing two cells.
One cell, cell A, is from a unicellular organism, and the other cell, cell B, is from a multicellular organism.
What functional differences will the scientist most likely see when comparing the two cells?
chloroplast - CORRECT ANSWER Which of the following organelles is found in most plant cells, but is
never found in animal cells?
The cell will not be able to maintain a stable internal environment. - CORRECT ANSWER What happens if
a cell is unable to get rid of its waste?
