How does the resolution of a specimen's image viewed under a compound light microscope compare to that of a scanning electron mi
sergiy2304 [10]

Answer:

A scanning electron microscope provides much better resolution than a compound light microscope.

Explanation:

The electron microscope uses a beam of electrons and heavy particle like gold for resolution. A compound light microscope works by using light beams and lenses.

The resolution of electron microscope is smaller then the compound microscope. This means that more smaller parts of the specimen can be seen by the electron microscope.

The magnification power of electron microscope is far better then the compound microscope. Hence, a more bigger image can bee seen through the electron microscope.

Which should a scientist conclude about data that are inconsistent with the current, scientific understanding of amphibian repro
Nikitich [7]

The Inconsistencies of the data are led to further investigations conclude about data that are inconsistent with the current, scientific understanding of amphibian reproduction

Option B

<h3><u>Explanation:</u></h3>

Class amphibia is one of the classes under the phylum chordata. This class has typical reproductive features. They are the animals that can live in both land and water, and a few are exclusively aquatic. But they essentially need water for the fertilization process. This is because they generally undergo external fertilization and the females lay eggs beside the water body. The males eject the sperms in water which swim through the water into the eggs and fertilize them.

This is the days old theory regarding the amphibia fertilization. But if some new theory comes up someday, that readily don't exclude this theory. The new theory has to pass through several tests and various further investigations where it's seen if the new theory explains most of the amphibia reproduction or not. Then it can be approved along side with the old theory.

Bradley decided to put a glass of water into the freezer, as he thought it would cool the water more quickly than the refrigerat
adelina 88 [10]

I believe it is because the glass has a smaller coefficient of linear expansion than the water. The glass undergoes thermal expansion and thus when it heats up, it expands and when it cools down it contracts. The inside and the outside of the glass does not reach an equilibrium temperature very quickly since the glass has a low thermal conductivity. The surface of the glass rapidly contracts while the inner surface is expanding which causes the glass to crack.
