HNRS Biology‚ Hour 2 20 March 2018 Darwinian Evolution on a Chip http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0060085 Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin and others‚ stating that all species of organisms arise and develop through the natural selection of small‚ inherited variations that increase the individual’s ability to compete‚ survive‚ and reproduce. Evolution is change in the heritable characteristics of

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

The purpose of this experiment was to observe the process of human evolution by observing similar features of the Pan troglodytes‚ Australopithecus afarensis‚ Homo erectus‚ Gorilla gorilla‚ Australopithecus boisei and the‚ Homo neanderthalensis in comparison to those of the Homo sapien. According to Darwinism‚ the species that had the most traits in common with the Homo sapien must be the most related while species with the least traits in common with the Homo sapien were the least similar. For example

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

Laura Lugo Group: Bianca Jonson Short lab report 10/4/14 Effect of household drugs on circulatory system of Lumbriculus Variegatus (blackworms) Hypothesis & justification part 1: In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate‚ an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1‚ we observed the basal rate of three different worms‚ and then placed the same three worms on different concentrations

The Evolution of Island Finches by Natural Selection The Evolution of Island Finches by Natural Selection The Evolution Lab experiment of finches located on two separate islands was conducted with purposes of evaluation and study of important principles of evaluation that include adaptation‚ natural selection process and finally the evolution process as a whole. In this study‚ "Darwin Island" and "Wallace Island" are lab environments that were used to conduct the experiment. By manipulating

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment
