Atrophic Scar Tissue Atrophic scars look like small dents or pits in the skin. They are normally an unusual shape‚ and tend to be jagged around the edges. A common‚ and the most likely‚ cause for people to have this type of scar will be due to having acne or chicken pox prior to scarring. They can occur anywhere on the body‚ but facial atrophic scars are what most people choose to have treated or covered with the use of camouflage creams. Atrophic scars are caused by the underlying tissues beneath

PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic. This is because the hydrogen

Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) --The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone‚ muscle-muscle‚ muscle- skin) A ligament‚ however‚ attaches to cartilage. (ie. cartilage-bone‚ cartilage-cartilage‚ bone-bone) 2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your

height with lung capacity of Year 9 students ! ! ! INTRODUCTION The capacity of our lungs is the volume of air our lungs can hold. Our lungs have a greater capacity than we use when we take a normal breath. Scientists use various terms to describe the different components of lung capacity. Tidal Volume is the amount of air breathed out in a single normal breath (inhalation and exhalation). The Inspiratory Reserve Volume is the amount of air you can inhale over and above a normal breath.

Telomerase Reactivation Reverses Tissue Degeneration in Aged Telomerase-deficient Mice Jaskelioff et al.‚ Nature‚ January 2011 This study looked at the effects of telomerase activation on the tissues of prematurely-aged adult mice. The telomerase enzyme‚ TERT-ER‚ is not expressed in the cells of these mice. The group induced (turned on) expression of TERT-ER by exposing mice to the compound 4-OHT‚ 4-hydroxytamoxifen (see definitions on next page). This treatment rebuilt the telomeres in

It is an organ just like the heart‚ lung and liver. It provides layer of protection and plays a vital role in maintaining body temperature and by making you aware of external stimuli through the sense of touch. The skin has two layers‚ the epidermis and the dermis‚ although not part of the skin‚ the hypodermis lies beneath the dermis
