Question

what is the name for the subunit which proteins are made out of? 1 point amino acids lipids nucleotides nuclei what is the key safety precaution when using flammable liquid such as ethanol? 1 point always mix with water to reduce reactivity keep the ethanol away from open flames always use at least 20 ft away from other people wear welding gloves while handling ethanol this is a required question if your eye is exposed to a chemical, what is the proper course of action? * 1 point nothing. its almost certainly fine wipe off your eyes with a damp cloth containing bleach immediately rinse of your eyes with emergency eye wash station

Explanation:

1. Proteins are composed of amino - acids. Lipids are fats, nucleotides are building blocks of nucleic acids, and nuclei are cell structures.
2. Ethanol is flammable, so keeping it away from open flames is crucial for safety. Mixing with water doesn't reduce its flammability in the context of fire - safety, using it a certain distance from people isn't the key safety measure related to its flammability, and welding gloves aren't necessary for handling ethanol.
3. When the eye is exposed to a chemical, immediate rinsing with an emergency eye - wash station is the proper action. Doing nothing is dangerous, and wiping with a bleach - containing cloth is harmful.

Answer:

1. A. Amino Acids
2. B. Keep the ethanol away from open flames
3. C. Immediately rinse of your eyes with emergency eye wash station
