In the book of biology of Mrtinez and Nazareno‚ there are nine characteristics of life just said and those are : a. Living things are highly organized and contain many complex chemical substances ; b. Living things are made up of one or more cells‚ which are

double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses‚ thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA into smaller fragments (called restriction fragments) and the highly specific way in which they do this has played a crucial role in the exponential advancement of biotechnology in recent decades. Restriction enzymes cut DNA at specific

Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both
