sores‚ growths‚ etc. Skin cancer is a deadly disease with many causes‚ but the only advantage is that it can be prevented. Skin cancer is a disease where cancer (malignant) cells are found on the outer layer of the skin (epidermis). The three types of cells found in the epidermis are squamous cells‚ basal cells‚ and melanocytes. These cells in time grow to be cancerous. Thus‚ the three types of skin cancers are squamous cell‚ basal cell‚ and melanoma. Melanoma is the most deadly and destructive type

Chapter 35 Plant Structure‚ Growth‚ and Development Lecture Outline Overview: Plastic Plants? • The fanwort‚ an aquatic weed‚ demonstrates the great developmental plasticity that is characteristic of plants. o The fanwort has feathery underwater leaves and large‚ flat‚ floating surface leaves. o Both leaf types have genetically identical cells‚ but the dissimilar environments in which they develop cause different genes involved in leaf formation to be turned on or off.

important role in protection and maintenance of body temperature and fluids (Cancer Treatment Center of America‚ 2007). According to the video‚ the skin is composed of three layers with each layer having different types of cells. The first layer is the Epidermis which is composed of basal‚ squamous‚ and melanocytes cells‚ its function is to shield and defend the internal layers of tissues and organs from having too much contact to UV sunlight. The second layer is the dermis and it is composed of “blood vessels

Osmolarity TITTLE: practical of estimation of osmolarity in tissues by bathing samples in hypertonic and hypotonic solutions. INTRODUCTION: Osmolarity is the osmolar concentration of plasma and is proportional to the number of particles per liter of solutions shown as (mmol/l). It is derived from the measures Na+ and K+‚ urea and glucose concentrations. Since the volume of solution changes with the amount of solute added also it change in temperature and pressure‚ osmolarity we can say it’s

The skin consists of the epidermis‚ dermis and the hypodermis. a. The epidermis is the outer layer. b. The dermis is the middle/second layer. c. The hypodermis is the layer (fatty) just under the skin The integumentary system also consists of epithelial membranes‚ accessory structures of the skin
