“All ethical statements are relative.” (By examining the justification for and implication of making this claim‚ decide whether or not you agree with it). The term ‘ethical’ can be defined as ‘morally correct’‚ however this leads to the question of what do we define as ‘morals’? A ‘moral’ can be simply defined as ‘concerned with the principles of right and wrong behaviour and the goodness or badness of human character’. The word ‘relative’ refers to something‚ which is ‘considered in relation

Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. It will also help to define diffusion and describe the process that occurs when certain solutes come in contact and are either stopped or move through the plasma membrane. Hypothesis I believe the plasma membrane is selective about what is able to and not able to pass

Analysis 1- Mirror neurons are cells that are actively firing both during a movement and while witnessing another perform the same movement. This can give insight into why sports fans get so worked up while watching a game. They are acting out; imitating what they see because the body is priming them. Their action neurons are firing just by watching‚ Kind of a monkey see monkey do scenario. The witnessing individual is adopting the other individuals’ point of view. 2- Mirror neurons contribute to feelings

Haymakers Resting is an oil painting by Camille Pissarro created in 1891. It was painted on a Canvas 25 3/4 x 32in large. The painting‚ as most of Pissarro’s works‚ is an impressionist piece with a rural theme. The technique used to create the painting is called pointillism‚ a common tool of impressionist. The painting depicts three farm women lying in loose hay. The women are plainly dressed‚ obviously workers who are either taking a breaking or coming to a stop for the day. The women wear plain

requires communication between your brain‚ muscles and organs. This starts with the neurons. Our organs sense things the brain needs to know. Signals are sent to the brain‚ it is decoded and then tells your brain what muscles to use and how. The signal is sent‚ a neurotransmitter. This is stored in the axon. An electrical impulse starts in the neuron. The charge is sent down the axon and this is how it starts. A neuron has three basic parts: the body or soma‚ the axon and the dendrites. The Cell

CELL TRANSPORT MECHANISMS AND PERMEABILITY Zack Johnson Human Anatomy & Physiology Lab 2101 Instructor: Alan Byboth‚ M.S. 10/4/12 Abstract- The cell is invaluable building block of all biological life on this planet‚ and one of its most important and unique characteristics is its ability to be selectively permeable with its plasma membrane. This outer membrane’s sophisticated mechanisms of transport through its bilayer are vital in maintaining homeostasis in the cell and the entire
