Answer:
(A). Energy is lost when machines don't work right.
Explanation:
The false statement from the choices is that energy is lost when machines do not work right.
The law of conservation of energy states that "energy can neither be created nor destroyed , they can only be converted from one form to another. "
- Option B is clearly covered by the statement of the law. All the energy of the universe is already created.
- Energy cannot be destroyed tallies with the Option C.
- Energy is transformed from one form to another validates the fourth choice. We can covert from thermal to mechanical energy and vice versa.
The only odd choice is that energy is lost when a machine doesn't work right.

Explanation:
Answer:
binary fission
Explanation:
The process by which Prokaryotic cells divide is known as binary fission.
prokaryotic cells are cells that do not have a nucleus and replicate through the process of binary fission
Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.
The other basic differences between the vertebrates and the invertebrates are that vertebrates have a spinal cord and a backbone while invertebrates lack them, vertebrates have well developed brain, lungs or gills in respiratory system and closed circulatory system.
