The nasal cavity is the hollow pipe (your nostril and upwards) that is covered with hairs and muscus membrane. Its main functions are to warm, moisturise, and filter air before it entering the body.
Hope it help :)

At the end of meiosis, there are FOUR cells with HALF the amount of DNA.
Meiosis is a kind of cell division that produces genetically different daughter cells. Unlike mitosis, which produces genetically identical cells, meiosis goes through 2 divisions that leads to 4 daughter cells.
In meiosis, the parent cell first duplicates all its genetic material, just like what they do in mitosis. Then it divides, leading 2 genetically identical daughter cells. Mitosis ends here, but in meiosis, the 2 cells divides themselves again, but without duplicating their DNA. This leads to the 4 daughter cells with only half of the number of chromosomes.
We call these cells haploid. They're usually common in gametes. For example, a normal body cell in human has 46 chromosome, but in the cells after meiosis, they only have 23.

The cessation of telomerase activity as we age limits the number of times a cell can replicate. current research on telomerases is particularly useful in the fight against cancer. This is because, Cancer cells employ a mechanism that activates telomerases, which leads to uncontrolled cellular division.
The body's stages of life are intimately correlated with telomerase activity. During the development of the embryo, the enzyme is active. High telomerase activity, which allows cells to divide endlessly, is a characteristic of cancer cells. In 85–95 percent of malignancies, telomerase is active (3,4).
