George is lifting weights. He starts by doing biceps curls
which involves flexing his
elbows. His elbow is able to bend
because the humero-ulnar joint is a hinge
joint. Sam is doing leg presses, extending his knees as he pushes
against the weights. Meanwhile, Jane is doing "lat pulls" by pulling
downward on a weighted bar. This movement involves adduction of her arms.
Her shoulder joint is a ball-and-socket joint, allowing
a wide range of movements.

Explanation:
The correct order starting from next to the object is
1. coverslip
2. objective lens
3. revolving nosepiece
4. body tube
5. body tube
A cover slip is a glass that is used to cover the specimen before observing through a microscope. Thus it is the nearest to the object.
Objective lens is the one which is near to the object hence it comes after the coverslip.
Revolving nose piece is a setup to which the objective lenses are attached thus it will come after the objective lens
Body tube is the hollow and tubular structure that forms the upper part of microscope.
While ocular lens also known as eyepiece are the farthest from the object , hence they come at the last.

Fossils in older rocks look less like the current living animals and plants. Some fossils found look either more or less like current species we know today.
