SKIN • Largest and heaviest organ of the body; accounts for about 15% of the total body weight • Also called as cutaneous membrane • Skin contains two layers‚ the epidermis and the dermis. • The hypodermis is the layer underneath the skin. FUNCTIONS • Skin is a protective covering that prevents harmful substances from entering the body. • It helps regulate body temperature and water loss. • It houses sensory receptors and contains immune system cells. • It synthesizes chemicals and excretes

Hypothesis: For an increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due

great point on demonstrating how a family would act and relate when they realize that the child that they have loved and nurtured all these years is not theirs. The families choose to get to know the children that they don’t know instead of doing the whole legal drama route. They get to know about the child that is biologically theirs and really discover how much love there is from the parent to child. This is so relatable to everyone because it is about family and how important family is. Love does

Layers of the skin The skin is an ever-changing organ that contains many specialized cells and structures. The skin functions as a protective barrier that interfaces with a sometimes-hostile environment. It is also very involved in maintaining the proper temperature for the body to function well. It gathers sensory information from the environment‚ and plays an active role in the immune system protecting us from disease. Understanding how the skin can function in these many ways starts with understanding

’Mockingbirds don’t do one thing but make music for us to enjoy. They don’t eat up people’s gardens‚ don’t nest in corncribs‚ they don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.’" - Atticus This relates to the text throughout the whole story. It is the core of the entire book. Blue-jays are the bad guys. Mockingbirds are the good guys. The bad people in this world deserve to be ‘shot’ but some do get away‚ so they are hard to hit. Whereas mockingbirds

which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the purpose

the failing grade she knows she will receive. The student decides to scribble notes onto her palm with a permanent marker‚ and later discover the consequences of cheating. The short story presents a metaphor–the permanence of cheating is similar to the permanence of a marker. The permanence of the marker is made more into a metaphoric meaning when the author writes‚ “Later‚ in the girl’s bathroom‚ you scrub the palm of your hand in the sink. When your hand is raw‚ you turn off the faucet‚ but the permanent

time through a central database? PeopleKey has the answer. How it WorksPeopleKey attendance systems utilize biometric time clocks (fingerprint readers) in order to safely and conveniently record students’ "in" and "out" times. First‚ students are enrolled into the system with a short PIN number‚ their name and their fingerprint template (an encrypted‚ mathematical representation of one’s fingerprint - not an image of the fingerprint itself).
