New cards

What is density?

How heavy an object is in relation to its size.

3
New cards

What can density determine?

It can determine if an object will float or sink when it enters a liquid.

4
New cards

What is buoyancy?

It is the upward force exerted by fluid, which determines how heavy or light an object is to float or sink.

What is the function of the kidneys?

Flitering blood and clearing it of any waste or excess water,

6
New cards

What is the function of the renal artery?

It carries the blood that the heart pumps towards the rest of the body.

7
New cards

What is the function of the renal vein?

It helps to carry unfiltered blood towards the kidneys.

8

Where is the renal artery located?

Right.

10

What is the function of the bladder?

It is a storage space for urine (excess water and waste in blood) that descends from the kidneys.

11
New cards

What is the function of the ureter?

They help transfer the excess waste and water filtered from the kidneys down to the bladder.

12
New cards

What is the function of the urethra?

It is the hole from which urine leaves the body.

13
New cards

What are the three methods of heat transfer?

Conduction, convection, radiation

14
New cards

How does heat transfer by conduction occur?

It occurs when heat is transferred from one object to another through direct contact.

15
New cards

How does heat transfer by convection occur?

It occurs when heat is transferred from one object to another through a secondary fluid conductor.

16
New cards

How does heat transfer by radiation occur?

It occurs when heat is transferred onto an object directly from electromagnetic waves.

17
New cards

What is an ionic bond?

It is a bond that happens when a metal atom transfers an electron to a non-metal atom.

18
New cards

What is a covalent bond?

It is a bond that occurs when two non-metal atoms share an electron.

19
New cards

What is the formula for percent of increase?

(Difference between values / Initial (lowest) value) * 100

20
New cards

What is the formula for percent of decrease?

(Difference of values / Initial (lowest) value) * 100

21

What is the formula for total prevalence rate?

Prevalence of second (unexposed) group - Prevalence of first (exposed) group
