Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.

You will often receive a printed guide that describes the experiment in depth in addition to verbal instructions, frequently with pictures and drawings.

It's important to pay attention as your teacher goes over the directions so you can complete the experiment correctly and securely when class starts.

<h3>What precaution should we take while experimenting in lab?</h3>

Be careful when handling chemicals, reagents, and stains, and heed all instructions. The contents and any potential hazards are listed on the labels of all bottles and containers. Avoid contact with the chemical and fumes, for instance, if the label instructs you to.

Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.

You can keep yourself safe in the lab with the appropriate clothing and tools. Depending on the experiment, your teacher should provide you with particular directions on what to wear to each class as each one calls for the use of various tools and substances that have varying degrees of hazard.

Though they are not something you should be preoccupied by, as mentioned above, accidents in school laboratories are rather common. Your teacher should review with you what safety equipment your lab contains.

Base your answer(s) to the following question(s) on the diagram below and on
Kryger [21]

Answer:

The correct option is <em>Both Cell A&D.</em>

Explanation:

The diagram in the picture shows how a cell (A) undergoes the process of replication and produces a cell (B) containing one full set of double chromosomes.

Then, the cell undergoes the process of mitosis to produce two daughter cells (C & D).

Mitosis can be described as a method of asexual reproduction in which the daughter cells produced are identical to the parent cells and are also identical to each other. Hence, the genetic content of the cell C will be the same as the genetic content of cells A & D.
