(10x)(40x)=400x The 4 Unifying Theories of Biology 1. The Cell Theory: Robert Hooke observed cells. All organisms are composed of cells that have DNA. 2. The Gene Theory: DNA is made up of nucleotides that contain a sequence. The sequence can be changed by mutation or crossing over. 3. The Theory

HISTORY OF THEORY OF EVOLUTION In 1543‚ a young Flemish anatomist Andreas Vesalius challenged Galen’s theories of the Human Body. This discovery had an impact on scientists. Vesalius’ discovery of the important differences between species also helped usher in the science of comparative anatomy‚ in which researchers studied animals to find their similarities and differences. In the process‚ they gradually began to recognize humans as being one species among many‚ with a few unique traits but

I have always been a very naturally inquisitive and enthusiastic person‚ especially when it involved disease and the impacts it has on the body as well as society. The recent media attention on diseases in the tropics (such as Ebola and MERS) has only heightened my fascination with disease and I am extremely interested in learning more and entering the field in the future as a scientist. Diseases are rapidly changing and evolving‚ and thus we have having to change our approach to how we monitor‚

life is effected by various environmental factors and in turn they modify their environment in various ways. The main theme of ecological studies is the relationship between organisms and environment‚ so ecology may well be called as "Environmental Biology." Growth‚ development and destruction of all organisms is determined by physical and biological conditions‚ their extremes and their interactions. Environment determines the destiny of a living organism. Plants growing in any particular place fully

experimentation‚ usually to ensure whether a product is safe for humans or not. However‚ animal testing is used worldwide‚ and its purpose ranges from guaranteeing the safety of domestic products to aiding medical research‚ particularly in the areas of biology and chemistry. This has always been a very controversial issue‚ but it first became a concern of Great Britain when in 1822‚ the country passed the Martin’s Act‚ which outlaws farm animal cruelty.

consists of the interactions among plants‚ animals‚ soil‚ water‚ temperature‚ light‚ and other living and non-living things. The word environment is used to talk about many things. People in different fields of knowledge (like history‚ geography or biology) use the word differently. An electromagnetic environment is the various radio waves that equipment such as radio and radar can meet. Galactic environment refers to conditions between the stars.

working in a group of people you come up with things for your experiment as in what procedure you’re creating. During your collaborations you discover things that happen as a whole instead of as an individual. An example of collaboration was during biology we came up with ideas to create a procedure for the gummy bear lab as a class to get the same data Communications is defined by talking with others about the information you gathered.
