A scanning electron microscope fires electrons at surfaces, and by detecting scattered electrons that reflect off the surface tells something about the surface topography. Transmission electron microscopy fires electrons through thin samples. The scattering of electrons as they go through the sample tells something about the structure. Both types of microscope utilise electrons in order to image a sample.

Lilit [14]

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.

melamori03 [73]

Answer:

The correct order starting from next to the object is

1. coverslip

2. objective lens

3. revolving nosepiece

4. body tube

5. body tube

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.

Why are fossilized organisms so different from the animals on Earth today?
Sonbull [250]

Answer:

Fossils provide evidence about life on Earth that currently extinct. Through fossils, we've discovered several species of animals and plants that previously existed. We also learn how life on Earth changed throughout the years. Fossils found in younger rocks look like animals and plants that are living today. 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.
