<h2>Order of parts of a microscope </h2>

First – ocular lens

Second – Body tube

Third – Revolving Nosepiece

Fourth – Objective lens

Fifth – Coverslip

Explanation:

Ocular lens: The lens present in the eyepiece at the top of the microscope, close to the eyes, through which a person looks through the microscope to view the specimen. Magnification of ocular lens in a compound microscope is usually 10x

Body tube: The tube that connects the eyepiece with the objective of the microscope for continuous optical alignment.

Revolving Nosepiece: The turret that holds the objective and revolves to select the objective lens according to its magnification

Objective lens: The objective lens is located above the specimen rack. Objective lens creates the primary image of the specimen viewed through the eyepiece. A single compound microscope can have more than two objective lens and their magnification ranges from 4x, 10x, 40x, 100x power.

Coverslip: The cover glass which covers the objective lens and prevent from touching the specimen . This is the object directly above the specimen.

How do paleontologist learn about evolution ?

DanielleElmas [232]

Paleontologists can identify organisms that may be ancient relatives of those living today. By looking at fossils they can also suggest how these organisms lived together in an ancient habitat. Few organisms become fossilized because the circumstances that an organism has to be in is very specific.

In science why is it important to have more than one piece of evidence to support your claim?

My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

In a sample of double-stranded DNA, 10 percent of the nitrogenous bases are guanine (G). What percentage of the nitrogenous base

DanielleElmas [232]

Answer:

40%

Explanation:

Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.

If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.

The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.

Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.
