and canals that packages protein molecules for secretion* Correct!
Golgi apparatus—particles, composed of protein and RNA, which synthesize
proteins
Cells are placed in a solution that causes them to absorb liquid until they burst.
When more water is removed from the solution, newly added cells do not burst.
, The original solutions was __________ , while the second was __________ to the
cells. - ANSWER-hypotonic; isotonic
An isotonic solution - ANSWER-has the same osmotic pressure as the cells in the
solution.

Programmed cell death occurs during development, including the removal of
webbing between fingers of the fetus. This process is known as - ANSWER-
apoptosis.
Which of the following is an example of catabolism? - ANSWER-The breakdown
of glucose in the cytoplasm and mitochondria
Dehydration synthesis reactions __________ , whereas hydrolysis reactions
__________ . - ANSWER-lose H 2O as bonds are formed; use H 2O to break
bonds.
Which of the following is not a characteristic of enzymes? - ANSWER-They speed
up the rate of chemical reactions but are not used up in the process.
They have active sites and interact with specific substrates.
*They are most active at temperatures above 53 degrees C.* Correct!
Most are proteins.
