poem The Frog and the Nightingale. 2. Anthropomorphism in Literature Anthropomorphized animals are frequently used to portray stereotyped characters with which the author quickly conveys the character traits. George Orwell’s Animal Farm and animated films such as Disney’s Robin Hood (1973 film) in which a lion is the king and the little character is a fox. Most famous children’s television characters are anthropomorphized funny animals such as Mickey Mouse‚ Bugs Bunny and Kermit the Frog as well

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

Eat That Frog! 21 Great Ways to Stop Procrastinating and Get More Done in Less Time by Brian Tracy There’s an old saying... "If the first thing you do when you wake up in the morning is eat a live frog‚ then nothing worse can happen for the rest of the day!" Brian Tracy says that your “frog” should be the most difficult item on your things to-do list‚ the one you’re most likely to procrastinate on; because‚ if you eat that first‚ it’ll give you energy and momentum for the rest of the day.

Holding the upper part of the frog firmly in one hand pull the skin down off of the leg. Be careful when pull the skin off around the knee as it is attached more firmly there. Place the frog dorsal side up in the tray and make sure to keep the muscles moist with ringer solution at all times. Using a blunt (glass) probe separate the muscles of the upper thigh

Cardiovascular Diseases Cardiovascular disease is defined as a disease that affects any area of the cardiovascular system‚ including the heart and blood vessels‚ and covers a range of diseases such as arteriosclerosis‚ atherosclerosis and coronary heart disease. Diet plays a vital part in the prevention and control of these diseases however other manageable factors such as smoking and physical inactivity also contribute to the diseases if not controlled correctly.

CARDIOVASCULAR FITNESS Cardiovascular fitness is frequently considered the most important aspect of physical fitness because those who possess it are likely to have a lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems
