Ionic Bond

Question 5

What is an Ionic Bond?

Answer 5

Metal atoms loses electrons to nonmetal atoms

Question 6

What is a Covalent Bond?

Answer 6

Non metal atoms sharing electrons

Question 7

What is a Hydrogen Bond?

Answer 7

Nonmetal atoms that attract electronegative and electrostatically

Question 8

It is when an atom loses,gains, and shares electrons to fill their valence shell with 8 electrons. What is this called?

Answer 8

The Octet Rule

Question 9

It is the movement of matierials through a membrane against a concentration gradient and requires ATP from the cell.
What is this called

Answer 9

Active Transport

Question 10

Answer 12

1. Fluid Balance
2. Muscular Contraction

Question 13

What are the 3 subatomic particles of atoms

Answer 13

1. Protons (+)
2. Neutrons
3. Electrons (-)

Question 14

Acids are the compounds that, when dissolved in water, dissociate to give….?

Answer 14

Hydrogen + (H+)

Question 15

Bases are compounds that, when dissolved in water, dissociate to give…?

Answer 15

Hydroxide (OH -)

Question 16

An ion that has LOST an electron and is positively charged, is called?

Answer 16

Cation (+)

Question 17

An ion that has gained an electron and is negatively charged, is called a?

Answer 17

Anion (-)

Question 18

What is the bond for Sodium and Chloride (NaCl)

Answer 18

Ionic Bond

Question 19

Differentiate Hydrostatic and Osmotic

Answer 19

Hydrostatic - water is pushed out of blood vessels, causing edema in tissues.

Osmotic - water is moved from a high concentration to a low concentration. water is sucked into vessels causing blood pressure to elevate.

Question 20

Name the types of Diffusions

Answer 20

Passive Transport

Osmosis

Diffusion

Question 21

Name fluid compartments of the body

Answer 21

Intracellular Fluid

Extracellular Fluid

Intercellular Fluid

Question 22

Explain the difference between active transportation and diffusion

Answer 22

Active Transport requires energy (ATP from the cells)

Diffusion does not require any energy
