what are the function of a objective lens and the ocular lenses

Answers

Answer 1

Answer:

Explanation:

The objective lens gather light from the specimen, magnifies the image of the specimen and projects the magnified image into the body tube. The ocular lens magnifies the image. It contains a measuring scale called a ocular micrometer.

Answer 2

the ocular lends magnifies so you can better see the specimen

Methane is a gas at room temperature and pressure. Explain why this is the case.

Answers

Answer:

hope it helps ❤

Explanation:

Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.

What inert (noble) gas structure do hydrogen and carbon atoms have in sodium chloride?

Answers

The answer above is correct (I took a test on this)

Using a lattice structure of sodium chloride, explain why sodium chloride:

a) forms crystals that are cubic in shape [2]

b) has a high melting point [2]

c) acts as an insulator when solid, but will conduct electricity when molten. [2]

Answers

Answer:

hope it helps plz mark me brainliest!

Explanation:

a) This pattern is repeated in all directions, giving a giant three-dimensional lattice structure in sodium chloride crystals. Because of the strong electrostatic forces between them, it takes a great deal of energy to separate the positive and negative ions in a crystal lattice.

b) Sodium chloride has a high melting and boiling point. There are strong electrostatic attractions between the positive and negative ions, and it takes a lot of heat energy to overcome them. Ionic substances all have high melting and boiling points.

c) In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

what is the magnification equation and how do you use it?

anyone ill give best answer branliest i swear

Answers

you need to work harder next time

hello!
the magnification equation is the eyepiece lens x objective lens.
you would use this equation for calculating the length of a cell and the magnification is used to find the length of an image

During the process of DNA replication, the whole molecule gets copied in the [A] phase of the cell cycle. The DNA strands are separated by the enzyme [B] while [C] keeps it from overwinding. The 2 strands are copied differently. The [D] strand is made continuously, while the [E] strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is [F]. This enzyme can only add nucleotides to an existing strand, so short sequences of [G] made by the enzyme [H] are needed for the process of elongation. In the [U] strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while [K] joins the fragments.
