HELP IM TIMEEE A student places a large pot of cold water on a stove and heats it for one minute. Then she takes the pot of water off the burner and places it on the counter. Which best describes the convection currents?

Convection currents move thermal energy from the stove to the pot, and then from the pot to the water.
After the stove is turned off, convection currents continue to transfer energy through the water for a period of time.
Convection currents in the water cause warmer, denser water to rise and transfer energy upward.
When the stove is turned on, convection currents cause an increase in the chemical energy of water molecules.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
