The skin is made up of thousands of tissues and its outer covering (epidermis) serves as a protector against germs. The skin is exposed to millions of germs‚ thus‚ it can easily get rid of germs that can cause allergies or other skin problems.

awaken the body’s immune system. b. Explain why beta radiation can be used in treating skin cancer but not cancers inside the body. Beta radiation is not bone penetrating like gamma radiation. The beta has a difficult time even penetrating the epidermis layer of skin and the dosage must be great to succeed. Gamma is penetrating and kills a great amount of cells. Beta is low level and kills only local cells. You can use gamma radiation on skin cancer; but there will be excessive skin death‚ as well

An acne scar can be deep or shallow‚ small or large‚ and dark or light in appearance. Even the best acne treatment in town cannot stop an acne scar from its development because the original structure has been compromised by the skin infection. The good news is that there are many effective ways to significantly lessen the appearance of an acne scar such that it becomes invisible to the naked eye. But not all acne scars are carved equal on the skin‚ pun not intended. Don’t expect an atrophic scar

These moths are well supported by east Texas farmers which the moths only live for 90 days and can spread over 100 miles per year. The larvae‚ in its adolescent stage‚ will feed on the protective environment of the cactus pad and leave only the epidermis to turn white‚ whither‚ and die. This type of characteristic helps kill the Prickly Pear safely instead of using chemicals. If somebody uses chemicals‚ the chemicals may soak into the ground killing the vegetation‚ ruining the soil‚ and ultimately

there are five pairs of vessels‚ which we loosely term "hearts‚" that connect the dorsal and the ventral vessels. These connecting vessels function as rudimentary hearts and force the blood into the ventral vessel. Since the outer covering (the epidermis) of the earthworm is so thin and is constantly moist‚ there is ample opportunity for exchange of gases‚ making this relatively inefficient system possible. There are also special organs in the earthworm for the removal of nitrogenous wastes. Still

Frogs actually lose their tail after leaving the larval stage and on the other hand‚ caecilians lack or have a small
