BIOLOGY Biology is the study of life -- life in all of its grandeur. From the very small algae to the very large elephant‚ life has a certain wonder about it. With that in mind‚ how do we know if something is living? Is a virus alive or dead? What are the characteristics of life? These are all very important questions with equally important answers. Characteristics of Life Living tings include both the visible worlds of animals and plants as well as the invisible world of bacteria and viruses.On

B6 - The Brain and Mind - 6 Mark Question Practice A. Neurones are specialised cells transmitting nerve impulses. There are two types of neurones; Sensory cells‚ which send impulses from the receptor to the central processing centre and the motor neurones‚ transmit impulses from the brain and spinal cord to the effector cell that will respond to the stimulus. Impulses flow along thin tubes of cytoplasm. In the sensory neurones‚ the cell body is located in the middle and two tubes

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

Free Will is defined as the ability of agents to make choices unconstrained by certain factors. Libertarians believe in free will and recognize that freedom and determinism are incompatible.. The determinist also follow the doctrine of incompatibility. According to A.J.
