Hope this helps!
Explanation:
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
Answer:
The liquid turns into a gas and the particles move around freely and fast.

Explain how a magnification of 400 x can be obtained using the lenses on a light microscope.
Answer:
Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).

Which statement describes the effect that a DNA mutation most likely has on an organism?
A. The mutation results in a gene that codes for a different protein.
B. The mutation causes the cell to no longer produce proteins from altered genes.
C. The mutation causes the cell to reject the existing genes and proteins made from those genes.
D. The mutation produces extra copies of genes that the cell uses as backups during protein production.
The mutation causes the cell to no longer produce proteins from altered genes. So, the correct option is (B).
What is Mutation?A mutation is defined as a change in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA where the viral genome consists of DNA or RNA.
Mutations are of following types:
Chromosomal Alterations.Point Mutations.Frameshift Mutations.Mutation plays an important role in evolution where the ultimate source of all genetic variation is mutation. Mutation is important as the first step in evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Thus, the mutation causes the cell to no longer produce proteins from altered genes. So, the correct option is (B).

Used to observe living organisms? Yes: alive or dead Yes: alive or dead No: dead only No: dead only
Does it produce a 2D or 3D image? 3D 2D 3D 2D
Surface and/or internal views? surface surface and internal surface, in great detail internal, including cellular organelles
Magnification 10X, 30X, 40X 40X, 100X, 400X (school) up to 2000X 1,500,000,000X and greater 200,000X
You are dissecting the mouthparts of arthropods, specifically this crayfish. This is a preserved specimen and your teacher has tasked you with dissecting the mouthparts and laying them out on the dissecting pan with the appropriate labels. Based on the information in the chart, select the best microscope for the job, citing evidence.
A) The crayfish is dead, a preserved specimen, so it would be appropriate to use either electron microscope for the task.
B) You should use the compound light microscope, on the lowest power. You can dissect the mouthparts using a 2D view with this much magnification.
C) The crayfish is a relatively large specimen, even the mouth parts. Since you are dissecting the mouth parts, you need a 3D view: you should use the dissecting microscope.
Eliminate
D) Because you are working in a high school lab, not a research or college lab, you have access to the compound light microscope, which may be used on living or dead specimens.

DNA carries the code to make what organic compound
Answer:
DNA in the cell nucleus carries a genetic code, which consists of sequences of adenine (A), thymine (T), guanine (G), and cytosine (C) (Figure 1). RNA, which contains uracil (U) instead of thymine, carries the code to protein-making sites in the cell. To make RNA, DNA pairs its bases with those of the “free” nucleotides.
