Introduction to Biology‚ Lesson 3 Essay Questions: 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 other. An example might be plants whose flower color is determined by incomplete dominance: white‚ pink‚ or red

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but University

Mr. Clark Honors Bio Period 3 10-19-13 Eukaryotic Cell vs. Prokaryotic Cell Eukaryotic cells do have a nucleus but Prokaryotic cells do not. Prokaryotic cells usually only have one chromosomes when Eukaryotic cell have more than one. Eukaryotic cells have mitochondria but Prokaryotic cells do not. Prokaryotic cells are usually unicellular and Eukaryotic cells are usually multicellular. Also Eukaryotic cells are larger than Prokaryotic cells. Both Eukaryotic and Prokaryotic cell have vacuoles

Biology- Change in pH Aim: To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known
