The scales on the fish serves as protection for the fish. And the tree bark serves as protection for the tree.
Diploid cells = 2n = 46
Haploid cells = n = 23
therefore, there are 23 chromosomes in haploid cells.
I thought it was savannah but grasslands could be it too.
Answer: 25 joules
Explanation:
Recall that kinetic energy is the energy possessed by a moving object.
So, kinetic energy = 1/2 X Mass X Velocity^2
Mass = 0.5kg
Velocity = 10m/s^2
= 1/2 x 0.5kg x 10^2
= 0.5 x 0.5 x 100
= 25 Joules
Thus, the kinetic energy of the moving ball is 25 joules
