Anaerobic organism

that different materials in this experiment represent real-life organisms and environments. The sand-coloured background represents a sand environment, while the green background represents a grass environment. The individual conducting the experiment is acting as the “predator” (bird) and the tweezers used by this individual is the beak of the bird. The toothpicks are the “prey” (worms). The beige worm is the original coloured organism, while the green worm has a colour mutation, aiding its…

The four forces of evolution include mutation, gene flow, genetic drift, and natural selection. Mutation occurs when the base pairs in DNA change which leads to different codons being read during translation. Most mutations create codons for the same amino acid that the normal codon would have made but sometimes a different amino acid is made and that leads to changes in the organism's phenotype. Gene flow happens when two different populations come together and reproduce with each other. The…

It has been proven that yeast can grow on both YPD and SD plates. In this lab we cross several yeast strains through the process called replica plating. For this identification test only one dominant allele is required. One copy of each gene is essential to produce enough of each enzyme needed in order to make a histidine. Through the study of Saccharomyces cerevisiae we prove that by transferring yeast cells onto YPD and SD plates over a period of 24-72 hours in a thirty degrees Celsius…

Robert Hooke Robert Hooke was known for many things that have affected the world we live in, from the discovery of certain cell parts to laws that he has made. He was an important person to our history. Even though Robert Hooke was a philosopher, architect, experimenter, etc. He also had an interesting life before he became known to science. He discovered many different things, and has affected biology and how we see things in a different way. Robert Hooke was born in England on July 28…

Animal Liberation” refers to the notion that all animals, regardless of their species, deserve freedom from exploitation and oppression. Animals are a major part of our environment, some people agree and there are those very few that will disagree with this topic. Recently, in the Guerin family we rescued two puppies that were found in rough situations. The first one, Ruger, was found in a crack house along with his two sisters. And Rilee, was found in a Dunkin’ Donuts parking lot. Since we…

Dinoflagellates are marine plankton, they are producers and have eukaryotic cells (meaning that the cells have a nucleus). Diatoms are unicellular, they are a type of algae. Cleaner shrimps free other organisms of parasites. Copepod are small crustaceans found in marine ecosystems. Ptereopods are a type of sea snail/slug. The type of squids, sharks and small fish found in a marine ecosystem depend on the abiotic elements. Amphipods are also a type of crustacean…

Cloning is a cell, cell product, or organism that is genetically identical to the unit or individual it is derived from. During the process of cloning, a piece of DNA is cut from its source with a restriction enzyme. Then, the DNA is put into a vector ( a DNA molecule used to transport genetic material into another cell). The vector is introduced to a host cell by the process called transformation, then the host cell copies the vector DNA with the original DNA; creating copies of the inserted…

Raven et al. (2014) defines biogeography as a study of the geographic distribution of species, and ties tougher how the species are related or not related and natural selection. Moseley et al. (2014) define biogeography as the study of patters that may form in the biotic environment and we can use the scientific process and information gathered from the past and present to study the distributions of plants and animals. Moseley et al. (2014) are the only authors that go into details about why we…

with weather influencing the way the water moves through the earth. Chapter 15 “The Ladder of Life” All living organisms follow the same ladder of life. . “ All living things are made of cells the chemical factories of life.” (Hazen & Trefil 252). But it goes even further than that, chemical Compounds, microscopic cells, cells to organs, to organ systems and then organisms. Even then organisms are categorized by kingdom ,phylom, class, order , family, genus, species. Everything living falls…

Regardless of the growth and resting phases of your hair being determined by genetics, a lot of people are able to grow their hair to a length midway down the back, successfully. A maximum length of hair growth of less than one foot would be uncommon. The natural restrictions on hair growth that govern eye lashes and arm hairs and prevent them from growing too much are the basis for these measurements. Dreadlocks are usually seen as being evidence of hair growth that is unlimited, however…
