Question 1: pH
To begin with, you remember that acids are at a pH below 7, bases are above 7, they turn litmus paper red or blue, and water is neutral. To further brush up your memory, you can refer to buffers. You decide to investigate further. Run the pH simulationand open the ‘Micro’ investigation. Notice on the simulation screen:

The pull down menu of substances at the top right
The 3 adjustable faucets on the right
pH scale in the middle
water components on left
Look at how the settings change with different substances.

Choose a substance such as battery acid (a 1.0 molar solution) with a pH of 1.0. Check the molecule and ratio boxes on the bottom of the screen.

Your objective is to discover what happens to the pH of battery acid when it is diluted with water. To find out, adjust the amount of battery acid to 0.5 liter (bottom faucet) and add water (top right faucet) to restore the volume to 1.0 liter (0.5 M). Record your answers for each of the following questions.

Part A

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.

Protein, a complex substance in all living things. Proteins are vital to life's chemical processes. Proteins can function as structural material (collagen, keratin), enzymes, hormones, oxygen transporters (hemoglobin), antibodies, or gene expression regulators.

In all living things, including bacteria and viruses, nucleic acids play a crucial role as large biomolecules. To store and express genomic information is a primary role of nucleic acids. Information for protein synthesis is stored in a form of DNA called deoxyribonucleic acid.

Thus, nucleic acid and proteins are significantly different from each other.
