In an The mass of a small stone was 27 g.
. The reading of the level of water in the graduated cylinder was 10 cm before the
stone was placed into the overflow can.
The reading of the level of water was 19 cm after the stone was placed into the
overflow can
(a) Calculate the volume of the stone.
(b) Calculate the density of the stone.

d = 3 g/cm³

Explanation:

Given data:

Mass of stone = 27 g

Volume of water = 10 cm³

Volume of water+ stone = 19 cm³

Volume of stone = ?

Density of stone = ?

Solution:

Volume of stone = total volume - volume of water

Volume of stone = 19 cm³ -  10 cm³

Volume of stone = 9 cm³

Density of stone:

d = m/v

d = 27 g/ 9 cm³

d = 3 g/cm³

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
