Answer:
The answer to your question is letter B. conservation of mass
Explanation:
A.molecular changes I think there is no molecular changes law so this option is discarded.
B.conservation of mass This law states that the number of products is equal to the amount of reactants so if chemical equations are balanced, they satisfied this law.
C.conservation of energy This law states that the total energy in an isolated system remains constant and is different from the chemical equations so this option is discarded.
D.products and reactants are elements of a chemical reaction but they are not a law, so this option is discarded.
Answer:
During the prophase of mitosis, the chromatin in a cell compacts to form condensed chromosomes; this condensation is required in order for the cell to divide properly. While mitotic cells have condensed chromosomes, interphase cells do not.

Answer:
think what you mean is that metal FEELS colder than wood if they're both at room temperature. That's because metal conducts heat much better than wood does. Since your hand is hotter than room temperature, both the metal and the wood conduct heat away from it.
Answer:
The answer to your question is: letter E
Explanation:
Endothermic process, is a process that needs energy to proceed.
A) ice melting We need to add energy to this process
B) water freezing It is not necessary to add energy in this process
C) boiling soup We need to add energy to this process
D) Hydrochloric acid and barium hydroxide are mixed at 25 °C: the temperature increases. This reaction happens without the addition of energy
E) Both A and C This option is correct because both processes needs the
addition of energy to proceed.
