Undertake tissue viabillity risk assessments. 1.1 Describe the anatomy and physiology of healthy skin. Skin is the largest organ of the body‚ covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19‚355 sq cm depending on age‚ height‚ and body size. The skin‚ along with its derivatives‚ nails‚ hair‚ sweat glands‚ and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has

those in the province‚ the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of phosphoric acid. B. Statement of the problem This study basically aims to find out whether a potato could be able to produce enough power to light up a bulb. And if it

Estimating Osmolarity by Change in Weight Abstract Optimum water content for normal physiological processes in plants is crucial. In order for normal activities to take place‚ the amount of water relative to osmotically active substance (OAS) in cells must be maintained within a reasonable range. The one way to estimate optimum water content is to find osmolarity of plants cells. Osmolarity can be indirectly measure by comparing change in weight and volume when plant cells are incubated in

Anthony Kiedis is a rock and roll drug and alcohol abuser who happens to be in one of the biggest bands today The Red Hot Chili Peppers. He wrote the book Scar Tissue to tell a story about himself and the wild road he took to get where he is today. The problem with the book is Anthony Kiedis strongest points are playing the guitar not telling a story in order and writing a book about it. It is more just rambling on and then this happened and then this happened. The Red Hot Chili Peppers have been

in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement of water into the potato pieces. Therefore

and outer tangential walls. Lacunar Collenchyma Lacunar collenchyma consist thickening around the cell walls facing the cavity lumen or intracellular spaces. Sclerenchyma tissue is composed of cells with rigid cell walls and they function to support the weight of a plant organ. The main function is as supporting tissues that withstands various strains resulting from stretching and bending which makes the plant elastics. There are two types of sclerenchyma cells which are fibers andsclereids. They
