Human skin has two lines of defense: the physical barrier consisting of multiple layers of cells that prevent pathogens from entering the body, and the immune system, which includes immune cells that can attack and destroy any pathogens that manage to penetrate the skin.

How many genomes will be found in a human skin cell?
A typical human skin cell will contain two complete sets of the human genome, one set inherited from each parent. This equates to a total of 46 chromosomes, made up of approximately 6.4 billion base pairs of DNA.
What two things never stop growing on a human?
Hair and nails are the two things on a human that never stop growing, although they do eventually reach a point where they stop growing longer.
What adverse effect can result from overexposure of human tissues to uv light?
Overexposure to UV light can lead to sunburn, skin aging, and an increased risk of skin cancer. Additionally, it can damage the DNA in skin cells, leading to mutations that may contribute to the development of skin cancer.
What are two names for the lines that run east to west on a globe?
Two names for the lines that run east to west on a globe are equator and latitude lines.
How many pairs of genes determine skin color?
Yes, skin pigmentation or melanin production is controlled by multiple genes that vary by ethnicity. For example, while Southern Europeans and East Asians have similar skin tones, these represent two separate evolutions and mechanisms for the suppression of melanin production. Furthermore, there is more human genetic variety in Africa than the rest of the world combined.
What are two types of immune respones in the second line of defence?
The body has three main lines of defense against pathogens. They are as follows:First line of defense: Skin, Mucous membranes, and Secretions of skin and mucous membranesSecond line of defense: Phagocytic white blood cells, Antimicrobial proteins, and the Inflammatory responseThird line of defense: Lymphocytes, and Antibodies
List two lines of nonspecific defense with examples of each?
External defenses - Includes skin and mucous membranes. Internal defenses - Includes phagocytic cells, inflammatory responses, and antimicrobial proteins.

First of all, you might want to spell DEFENSE correctly.
What two things protects the human heart?

What are two examples of continuous cell lines and primary cell lines?
Continuous cell lines include HeLa cells derived from cervical cancer and CHO cells derived from Chinese hamster ovary. Primary cell lines are freshly isolated cells that have not been sub-cultured extensively, such as human primary keratinocytes isolated from skin tissue and primary rat hepatocytes isolated from liver tissue.
What two things never stop growing on a human?
Hair and nails are the two things on a human that never stop growing, although they do eventually reach a point where they stop growing longer.
What are the two types of courts martial counsel?

What are the disadvantages of a mosquito?

Well just to name two: your nose hairs your saliva
