The epidermis contains what?
The epidermis contains skin cells.
The basal cell layer contains special cells called?
The basal cell layer contains special cells called:
what is the advantage of having many small cells instead of one large cell?
With smaller cells, there is a greater surface area.
How many nerve cells are in a cubic centimeter of the human brain?
200,000,000 (about). it has a ton of them
What is an organelle that contains the cells DNA?
Prokaryotic and Eukaryotic Cells
How many cells are in 1 square centimeter of your skin surface?
1 square centimeter of your skin's surface contains over 100,000 cells.
What is cell seeding density?
Cell seeding density refers the number of cells (usually per square centimeter) that are placed into a flask during cell passage. If growth is wanted a typical cell seeding density would be around 5,000 cells/square cm, however, if a high confluence is needed it may be more appropriate to seed cells around 50-60,000 cells/square cm. How to determine cell seeding density- look at the cells in a hemocytometer. This is a small plate that has very small squares etched into its surface, which allows for counting of individual cells underneath a microscope to determine the density of the cells in the cell suspension, and this the total number of cells can be approximated.
How many cells are in a square centimeter?
Roughly 1 billion but who's counting? There are 10 to 100 million viruses in one cubic cm of water or one gram of soil, unless I miss my guesstamate.
Do skin cells have ribosomes?
Skin cells on the surface are dead and therefore do not contain any functional organelles. The hypodermal layer (the layer beneath the visible skin) has active cells and contains ribosomes.
How does insulin enter animal cells?
Cholesterol enters animal cells when the animal consumes and processes something that contains cholesterol. The cholesterol then enters through the cells permeable surface.
What layer of skin that contains the blood vessels and nerves closest to the surface of of the skin is?
The upper layer of the skin is called the 'epidermis'. In birds, it contains no nerve cells, and their Merkel cells are located in the dermis. However, in most animals it contains a scattering of nerve cells called Merkel cells, located at the basal layer. The middle layer of the skin is called the 'dermis.' It contins blood vessels, most of the nerve cells, and other structures. The lower layer of the skin is called the 'sub-cutis' and mostly contains fat.
Have dead cells why is it an advantage to on the surface of the body?
Why is it an advantage to have dead cells on the surface of the body? Why is it an advantage to have dead cells on the surface of the body?
In cells structure that contains the cells genetic material and controls the cells activities?
Which structure contains a eukaryotic cells genetic material
Which layer of cells contains vascaular tissue?
Which layer of cells contains vascular tissue
Why do smaller cells have a greater surface area to volume ratio?
If the cells are spherical, the surface area increases as the square of the radius while the volume increases as the cube of the radius. Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas. Conversely, as the cells become smaller, their volumes decrease much more rapidly that their areas and so the surface area to volume increase. With non-spherical cells the calculations are much more complex, but the general pattern still applies.
In one hour how many skin cells does your body loose and replace?
The human skin cell shedding rate (called the desquamation rate) depends on factors such as the location of the skin being considered, the total area being considered, and the person's age. Even keeping the skin location, skin area, and age constant will result in different rates for different individuals. As an example, if we take the average rate of all subjects and all sample areas given in the Table 2 referenced above, we obtain an average rate of 945 cells per square centimeter per hour. Let's assume 945 cells per square centimeter per hour is close to the average desquamation rate for the entire body even though it depends on location and the table gives actual rates that vary from a low of 530 to a high of 1856. There are 10,000 square centimeters in a square meter. Average adult humans have a skin area of somewhere between 1.5 and 2.0 square meters. This means the average adult human has somewhere between 15,000 and 20,000 square centimeters of skin. Multiplying this area by the average of 945 cells per square centimeter per hour gives us 14,175,000 to 18,900,000 cells per hour or 340,200,000 to 453,600,000 cells per day
