Listed under are the 5 different type of cells found in the epidermis and their description:
1. Stem cells
These are what you call undifferentiated cells. These are cells found in the stratum basale, which is the deapest layer of the epidermis. These cells divide to create keratinocytes.
2. Keratinocytes
The make up the majority of the cells in the epidermis. They synthesize keratin which are proteins that make up your hair, skin, and nails. They can also be found in other organs inside your body.
3. Melanocytes
These cells can only be found in the stratum basale. They synthesize melanin with a brown to black pigment. These dark pigments serves as protection for the skin from harmful UV rays.
4.Merkel cells
Merkel cells are also known as <em>tactile cells</em>. They are the sensory receptor for touch. Merkel cells and the nerve fiber together are called the Merkel disc.
5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin.
Hope you find some information above that will help you.
Answer:
Adaptive radiation
Explanation:
Adaptive radiation refers to the evolution of the multiple species from one ancestral species. The force which drives the formation of new species is the change of natural environment like the availability of resources, niche, and many other related changes.
The species adapt themselves to these changes and get transformed into new species.
The formation of a variety of species of finches on the Galapagos island is an example of adaptive radiation. The species formed as a result of the food resources they received on the island.
Thus, Adaptive radiation is the correct answer.
If the allele frequency of a gene for brown fur is increasing from 15 to 25 percent, the population of the bears is evolving.
Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family .
The concept here is that God did not tell Noah when it was going to rain. The people of the day most probably mocked and derided Noah as a time waster or a fool. That is, until the flood came. The " fool" had been wiser all along.
An Application is this. Google gives everyone who does online business "suggestions" and "guidelines" but not everyone chooses to listen. Google rarely, if ever, tells us when they will put the guidelines into action.
Panda, a Google ranking system, took 6 years while Google was telling online users to follow certain guidelines. Many ignored, until Panda was put into action, and those who had not heeded suffered with only themselves to blame.
Moral: Heed and prepare even if the outcome tarries.
