How many cells are in a human body​
prisoha [69]

Hey Brainly Student!

I found this in wonderopolis.org: “Scientists concluded that the average human body contains approximately 37.2 trillion cells! Of course, your body will have more or fewer cells than that total, depending upon how your size compares to the average human being, but that's a good starting point for estimating the number of cells in your own body!”

This is an estimation and there is not an exact amount because everyone is different :)

3. Were there any stages of the cell cycle that you did not observe? How can you explain this using evidence from the cell cycle
mario62 [17]

Answer:

The surface area of the cell increases to volume ratio

Explanation:

As a cell grows, the surface area of the cell increases to volume ratio. When cell division occurs, the surface area is distributed and each daughter cell have less surface area but with the passage of time, the surface area increases. The main function of mitosis is to increase the population of the cell, the cell must be divided into two daughter cells in the process of mitosis. Tumors occurs when the process of mitosis is uncontrollable. One observation that is found interesting while looking at the onion root tip cells is the multiplication of the cells by the process of mitosis.

Why do you think molds are not growing all over everything around you?
Olegator [25]

Because:

Not everything around you has the correct moisture to grow mold. Places like a shower, wood, and even toilets do, since water will soak into them, or the water is trapped. If you don't clean your shower and toilet, you will notice mold. If you look at a fence, there is probably hints of mold on it.

Something like a shelf cannot grow mold, since it usually has paint on it, and the moisture won't go through something like paint.

Another possible answer: Since the areas around you don't always have the correct moisture, mold will not grow on everything. It can grow on some stuff in your house, but not everything around you.
