- Use appropriate cut-resistant gloves to handle broken glass.
- Use forceps, tongs, scoops, or other mechanical devices for removing or retrieving broken glass from the work area or a fume hood.
- A dustpan and brush should be used to clean up shards/small pieces of broken glass, Pasteur pipettes, or shards of glass.
Explanation:
Never use broken or chipped glassware. ... Dispose of the glassware in the proper container. Glassware that is chipped, cracked or broken can cause cuts. Material placed in broken or chipped glassware may leak.

Answer: Between 8 and 14
Explanation: Ammonia is an inorganic compound of formula NH₃. Also known as ammonium hydroxide, it behaves as a weak base.
pHydrion paper is a chemical test indicator, i.e., it indicates the pH of a substance.
If inserted in Ammonia, pHydrion will indicate a range of 8 to 14 because in pH scale, indication of base is over 8 and up to 14. The exact number depends on the hydrogen ion concentration of the substance.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
The answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.
Option a is the correct answer
<h3>What is a neuron?</h3>
A neuron is defined as structural and functional unit of the nervous system
Complete question:
In humans, adult brain cells called neurons are terminally differentiated. This means that they are completely mature and no longer undergo the cell cycle.
Which of the following statements best describes how the cell cycle relates to neurons?
a. Neurons do not go through M phase.
b. Neurons passes through the M phase
c. None of the above
So therefore, the answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.
