Dissolving can separate the three. Because pepper doesn't mix with water and neither do pebbles.
<u>Answer:</u> The average kinetic energy of helium atoms is 
<u>Explanation:</u>
To calculate the average kinetic energy of the atom, we use the equation:

where,
K = average kinetic energy = ?
k = Boltzmann constant = 
T = temperature = 
Putting values in above equation, we get:

Hence, the average kinetic energy of helium atoms is 
Answer:
In mitosis, the products are identical to the parent cell, while in meiosis the products are different from the parent cell.
Explanation:
Mitosis replicates DNA at the beginning of the process, so it's always the same, but Meiosis uses a special process called crossing over which causes two chromosomes to swap information, which means that the DNA has changed.
