Which of the following work by robert hooke most likely impacted later scientists who developed the theory that all organisms are made of cells?
a. hooke’s conclusion that the distance that a spring stretches is proportional to the force that is pulling it apart
b. hooke’s invention of a mechanical, portable watch to tell time
c. hooke’s use of the telescope to discover that stars are attracted more to one another when they are closer together
d. hooke’s use of the microscope to observe and compare dead wood to living wood

The correct answer is "Hooke’s use of the microscope to observe and compare dead wood to living wood."

Explanation:

Robert Hooke observed a sliver of cork under the microscope and noticed pores in them which he later called cells. Hooke believed that these pore carried the life juice of the once living plant. Hooke and his contemporaries believed that only plants were made up of cells.  Hooke then went on to record his observations on these microscopic structures.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
