What are the two recognized means of preventing injury during electrical equipment operation?
baherus [9]
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.

If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
artcher [175]

Answer:

26%

Explanation:

Adenine pairs with thymine.

Guanine pairs with cytosine.

If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.

100 - 48 = 52

Then divide by 2 because you have guanine AND cytosine.

52/2 = 26

Therefore, your final answer is 26% of guanine is in the DNA molecule.

Darin wanted to make amino acids. He took the protein collagen and heated it to the point of denaturation at physiological pH. W
Svetllana [295]

Answer:

No, because he will not have broken covalent bond.

Explanation:

Denaturation  is the process adopted to affect or alter the chemical structure of a protein. This can be done or achieved by heat or addition of acid.

Denaturation can't break the peptide bond of the protein , this means that the , amino acid sequence is unaffected after the process.

Physiological pH is the pH Darin won't be able to have amino acid because the pH at which denaturation was being carried is basic, while the process requires acidic medium.

Collagen is a form of protein that can be found in the body.
