Claim Evidence Reasoning. Evaluate the following claim: Meiosis is different than Mitosis.
likoan [24]

Answer/Explanation:

Yes, although they have similarities, meiosis and mitosis are different.

<h3>Similarities</h3>

Meiosis and mitosis are both types of cell division that results in the production of daughter cells.

They go through similar processes of prophase, metaphase, anaphase, and telophase.

<h3>Differences</h3>

However, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.

Meiosis produces four genetically different haploid cells from a diploid parent cell.

There are two rounds of cell division in meiosis, and only one round in mitosis.

JulijaS [17]

you should

a. tie it back before performing lab work.

Using a Bunsen burner can cause your hair to loosen and ignite. Bring only your essentials to the lab. This means that all personal belongings such as bags and jackets should be kept outside. Long hair and loose clothing that can get caught in glassware or pose a danger in the laboratory should be withdrawn.

Wear proper clothing when working in the laboratory. Long hair, hanging jewels, loose clothing, and baggy clothing are dangerous in the laboratory. Long hair should be tied at the back. You need to secure the removed jewelery (if it's hanging long) and loose clothing. Shoes should completely cover your feet.
