Nature is when a person is influenced by the inherited genes and nuture is when a person is influenced by the environment and surroundings. One example of nature would b when a person has brown haircolor naturally and that person nurtures it by changing the color to black.clearly the black …

What is DNA Fingerprint? Be it in movies, television or books and magazines, DNA has constantly been hailed as the ‘building blocks of life”. DNA is present in every living organism. It is a molecule that encodes the basic genetic instructions for the development and functioning of an organism. This …

Compare and contrast directional selection and disruptive selection, and provide an example of each. Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a “bell curve.” Selection against one of the extreme phenotypes causes the distribution to move in one direction or the …

Macroevolution refers to major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. Examples of this would be fish descending from an invertebrate animal, or whales descending from a land mammal. The evolutionary concept demands these bizarre changes. Microevolution refers to …

What is DNA? Where is it found? DNA is the basic building blocks of the genetic makeup, and is found in a variety of places in the body such as: blood cells, skin cells, tissues, muscles, bone, teeth, hair, and saliva. What is mitochondrial DNA? Mitochondrial DNA is a small …

  Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies, placing them in media, and letting them cross breed, we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their …

Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained …

A number of steps are required to isolate DNA from cellular contents. Describe what happens at each step, and why it acts to separate the parts of the cell. /6 There are three specific steps required to isolate DNA from its cellular contents. The steps used to remove and expose …

The positivist theory is centred on the idea of a scientific understanding of criminality and crime. A key assumption in this field of study is that there is a definite distinction between ‘normal’ (in terms of human nature), and the ‘deviant’. For positivists, the occurrence of crime is explained by …
