7 0

Energy = mass ×specific heat capacity×change in temperature'

In this case, the mass of water is 50 kg, the specific heat capacity of water is 4184J/kg

the change in temperature is 80-45= 35 degrees celcius

Therefore, heat energy

           = 50 ×35 ×4184=7322000 Joules

But 1kJ =1000 Joules

therefore, the energy needed will be 7322 kJ

Chromosome duplication occurs for the beginning of which process? select all that apply.
Vladimir [108]

The image shows the process of mitosis. The replication of DNA happens at prophase of the mitosis process. This results in the duplication of the chromosomes This is followed by the segregation and division of the duplicated chromosomes into the two daughter cells. The same applies to the meiosis process where the DNA replication and duplication are followed in the same manner as mitosis. Hence the duplication of chromosomes happen at the beginning of both mitosis and meiosis processes.
