When an animal gets overheated, homeostasis will cause theanimal to sweat and pant in an effort to maintain internal stability. Which situation shows a similar example of homeostasis in cells?

• A cell is invaded by a virus

• A cell’s nucleus sends signals throughout the cell in order to produce protein.

• Water enters a cell through the cell membrane because the cell is dehydrated.

• A cell goes through mitosis, producing a new cell.

Which type of cell has the closest structure or organelle that functions like a human skeletal system, which provides shape and structure?

• Animal cell

• Bacterial cell

• Virus

• Plant cell

Many cellular functions can be compared with functions that occur in organisms. Which of the following is NOT a function that both the cell and the organism share?

• Stores waste material for removal

• Provides structure and support

• Learned behaviors that aide in survival

• Conversion of nutrients into usable energy

A person develops fever from a bacterial infection. This fever is a response from the body to help fight the infection by —

• increasing the body's heartbeat rate

• increasing the energy level of the body

• slowing the growth of the bacterial infection

• stopping additional bacteria from entering the body

One of the functions of the skeletal system in the body is to

• circulate blood to all parts of the body

• collect waste products and remove them from the body

• provide a strong framework for the body

• produce enzymes to help digest food

• They lay eggs that must incubate in water.

• They have very dark fur and skin.

Which structures differentiate plant cells from animal cells?

• 1, 4, 8, 9

• 2, 4, 9

• 1, 2, 4

• 2, 4, 8
