to contain instructions for growth‚ work and maintenance of the cell‚ it controls nearly all the activities of the cell. "A smaller‚ darker sphere is often visible‚ the nucleolus‚ this is a source of ribonucleic acid (RNA) one of the nucleic acids" [2]. When a cell is not dividing (known as resting) this is called the chromatin network and the nuclear material appears like a thick‚ triangle mass. When a cell is in the process of dividing‚ the chromatin network separates into distinct black threads

Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

Physiology : Eating • Digestive system – stores and uses energy – Absorption & Fasting – See diagrams • Describe how brain & rest of body controls eating (100%) or role of Hypothalamus Metabolism – Absorption & Fasting When we eat we must obtain adequate amounts of carbohydrates‚ fats‚ amino acids‚ vitamins and minerals to construct and maintain our organs‚ to obtain energy for muscular movement and for keeping our bodies warm. Most of the molecules we eat get ‘burned’ to provide the

Physiology Assignment Name Class Date Every organism has specific characteristics that make it ideal for living in the certain environment that it resides. For example‚ owls are birds that have adapted to hunting at night. They have many adaptations that allow them to be successful night hunters. One adaptation that the owl has involves their eyesight. The eyes of owls are sunk in. This allows an owl to collect and intensify light making it better able

Exercise 8 Simple Muscle Contraction • 3 Phases AB - lag phase or latent phase - (shortest) 0.00sec‚ usually less than 0.01sec - brief period that exists between the application of the stimulus and the start of contraction BC - contraction‚ 0.05sec - peak - shortening of the muscle occur CD - relaxation period‚ 0.05 sec - Occurs when Ca+ is transported back in the sarcoplasmic reticulum Single muscle contraction= 100vib/sec (tuning fork)= 0.10 sec 10vib (result) Neuromuscular junction - formed when

A DNA molecule which is abbreviation for deoxyribonucleic acid is made up of very long chains of monomers and polymers that are called nucleotides. These two chains in particular which composes of DNA strain are then formed by the grouping of the nucleotides into the polynucleotides. The

all members in a group‚ not only because people have different physical traits‚ but also different diet and living habits. There are three major body types: Ectomorph‚ endomorph and mesomorph. People who are described as Ectomorphs usually have lean muscle mass; they have small frames and do not gain weight easily‚ and therefore‚ have a slim appearance. Ectomorphs have long limbs‚ narrow hips and small shoulder width; their muscule strength is usually unable to afford heavy training‚ and therefore‚
