A biology blog for students
The greenhouse effect is currently one of the most popular debate topics among not only environmentalists, but also the general public. It is also mainly discussed in several school curriculums such as biology, ESS, and geography. They are produced mainly by three producers: the United States, China, and the European nations. These gases are carried... Continue Reading →
Photosynthesis is one of the most heavily discussed topics in biology courses. Probably a reason why they are regarded as such an important topic is because they have impacted Earth's atmosphere in the course of centuries if not thousands of years. Today we will take a look at how photosynthesis altered Earth's atmosphere for millions... Continue Reading →
Meselson and Stahl, although their names may not be heard so often, played a huge role in figuring out the replication of DNA in bacteria. Through their meticulously-designed experiments, they discovered that DNA replicates in a semi-conservative way. Diagram of Meselson and Stahl's Experiment (Khan Academy) There were three possible ways DNA replication could happen:... Continue Reading →
Davson and Danielli were two scientists who proposed their model of the cell membrane in 1935, which were then revised in 1954. Earlier in 1925, Gorter and Grendal claimed that the ratio of total lipid surface area to total cell membrane surface area was 2:1, concluding that a layer of fatty molecules that is two...

On the last post, we talked about the polarity and thermal properties of water. Today we will continue on the discussion of properties of water and move on to the cohesive, adhesive, and solvent properties. Cohesive Properties of Water The definition of cohesion is the "binding together of two molecules of the same type." Water... Continue Reading →
