Power is defined as Work / Time.
With this formula, we can solve.

As of now, we are looking for the power
P=
We have 2,000J of work and 80s (simplified into seconds).
2,000 / 80

Rewrite our transitions into an equation.
P = 2,000 / 80

Divide 2,000 by 80.
2,000 / 80 = 25.

Your answer is:
25W (W is the unit for Watts)

I hope this helps!

How does gene expression lead to differentiation
ExtremeBDS [4]
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
