Answer 18

Hypotonic

Answer 24

Interferons

Question 25

What do macrophages and dendrites release to signal other white blood cells to act?

Answer 25

Cytokines

Question 26

What white blood cells are not associated with adaptive immunity and aren’t associated with antibodies

Answer 26

Natural Killer cells

Question 27

Differentiate between innate and adaptive immunity

Answer 27

Innate: Must create new antibodies to fight because you haven’t had the illness before
Adaptive: Already have had illness, so have the right antibodies to fight it.

Question 28

What is osmosis?

Answer 28

The movement of water into and out of a cell through a semi-permeable membrane.

Question 29

Define anitgen

Answer 29

An infection or virus that antibodies target. Can cause illness.

Question 30

List 2 organelles that plant cells have and animal cells never have

Answer 30

Cell wall, chloroplast

Question 31

Define aquaporin

Answer 31

How water molecules can enter the cell, channels

Question 32

What is one function of proteoglycans?

Answer 32

Regulates the passage of molecules through ECM to plasma membrane.

Question 33

How does exocytosis occur within a cell

Answer 33

The vesicle fuses with plasma membrane as secretion occurs, the vesicle membrane becomes part of the plasma membrane which can then expel.
