Explanation:
Enthalpy is the change in energy. A cold pack will react endothermically and enthalpy will be positive and a heat pack will have negative enthalpy. You cannot determine which has more change in enthalpy unless you measure the temperature change. Eg. a heat pack went from 25c to 35c will have greater change in enthalpy then a cold pack going from 25 to 20c because the net temperature difference is greater
structural, plant and animal cells are very similar because they are both eukaryotic cells. they both contain membrane-bound organelle such as the nucleus, endoplasmic, mitochondria etc
