ONE of biology’s hottest topics is epigenetics. The term itself covers a multitude of sins. Strictly speaking‚ it refers to the regulation of gene expression by the chemical modification of DNA‚ or of the histone proteins in which DNA is usually wrapped. This modification is either the addition of methyl groups (a carbon atom and three hydrogens) to the DNA or of acetyl groups (two carbons‚ three hydrogens and an oxygen) to the histones. Methylation switches genes off. Acetylation switches them on

Callum Bourke Describe the long term effects of exercise on the Muskoskeletal system and energy systems. (P3) Describe the long term effects of exercise on the cardiovascular and respiratory systems. (P4) Cardiovascular System Cardiac Hypertrophy The heart increases in size and volume; this allows more blood to enter the heart allowing a greater amount of oxygenated blood to be pumped to the working muscles. To withstand the large amount of blood‚ the left ventricle becomes thicker

Capillaries exchange fluids‚ gasses‚ heat‚ nutrients and wastes to the tissues through diffusion. Capillary walls contain small pores that are selectively permeable allowing only certain molecules to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure

flaws on your face or to enhance the skin appearance. It is usually done with two kinds of laser. One is ablative or wounding laser that eliminates thin skin layers and the other being a non-ablative or non-wounding laser that boosts the growth of collagen and tightens up the underlying skin. Non-ablative laser resurfacing being less invasive requires little time for recovery. However it is not as effective as ablative laser resurfacing. The Carbon dioxide laser is the widely used kind of laser that

the bones ( literally the word osteoporosis means “ porous bone” ) leading to increased risk of bone fractures. The bone strength has two main properties‚ the mass and the quality of the bone. The bone is a living tissue made up of tough elastic collagen fibers and minerals and contains cells that make and moulds itself in a process called bone resorption‚ it also forms the rigid skeletal framework that protects body organs. Osteoporosis is influenced by various factors such as genetic‚ sex‚ hormones
