Prokaryotes (meaning before nucleus) are put in two domains: Bacteria and Archea (Biology Department, 2015). Eukaryotes on the other hand, (which have nuclei), are in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way to distinguish between classes comes from observations made about their structure. Prokaryotic cells are smaller than eukaryotic ones; the typical prokaryote ranging from 100 nm - 10…

would enforce their rights. Their have been so many cases of police brutality and it was usually because some officers believe that they are allowed to use brutality because they know they will get away with it. Back in 1963 there was a case of a protist run by African-American and a police officer brutally injured the leader of the protest that eventually led him to his death. Police paternity is not only used against African-American people it is also used against others who have a different…

Sexual reproduction is a type of reproduction in which two different cells combine, which create an offspring. When two cells called the egg for female, and sperm for male, combine and join together they create a new organism called a zygote. During meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis has two divisions of the cytoplasm and the nucleus, the divisions are called Meiosis I and Meiosis II. Reproductive cells go through interphase before meiosis. “ A…

coral diseases affecting at least 150 scleractinian, gorgonian, and hydrozoan zooxanthellate species have been described in the Caribbean and Indo-Pacific (Sutherland et al. 2004). Most of these diseases have been caused by bacterial, fungal, and protist type pathogens as well the increased sea temperatures, pollution, and eutrophication. Sutherland et al. says that it is estimated that worldwide 27% of coral reefs have been lost with 16% at serious risk and the corals exhibiting diseases have…

Kane & Selsis (2014) proposed a modified Drake equation, originally intended as a “necro-biological” solution for the Fermi Paradox, involving pathogenic zombie apocalypses, signified by a measurable increase in greenhouse gas emissions (particularly CO2, H2S, NH4, and CH4) due to the rotting of zombified sophonts and their domesticated animals. While the report itself was in fact a practical joke (there are no real life mechanisms for a zombie apocalypse), it did call to attention serious…

Emma Potochny Sam Pappas 1. Background Information This should include background on the scientific question you wish to address, why it is important, information on the study species, and why it was chosen to answer this question. This information should lead the reader to the logical basis of your hypothesis. Animal models are still commonly used in product testing, especially for bath products. These substances are usually injected into or rubbed on the laboratory animals in eye or skin…

Life is recognized by what we do. People, animals, plants and insects encompass properties such as order, regulation, growth and development, processing energy, responding to the environment, reproduction, and evolution. All living organisms exist with nonliving factors, as such, their interactions form an ecosystem. The two main processes of an ecosystem are the recycling of chemical nutrients and the flow of energy. Cells are a component of all living organisms and essentially are life’s…

15. If true chemical bonds bind atoms together to form a molecule through electron sharing, what is special about a Hydrogen Bond that makes it not a true chemical bond? My Answer: B) Unequal distributions of the protons generates partial charges Correct Answer: A) Electrons are shared unequally between different atoms Why my answer was wrong: I did not realize that the answer says, “protons,” instead of, “electrons.” The protons are not distributed from the nucleus, because if they were, the…

Interactive Question 7.2 Cite some experimental evidence that indicates that membrane proteins drift. A good form of experimental evidence is Fluorescence Recovery After Photobleaching, aka FRAP. In the FRAP process, membrane proteins are labelled with a green fluorescent protein, and part of the plasma membrane is “bleached” with a laser, causing them to lose their fluorescence. The part that was bleached will eventually become fluorescent again, as molecules drift in by diffusion. How might…

kill most organisms. It has distinct domains that make them extremophiles, meaning that they can grow in more than one condition. Additionally, prokaryotes include cells that have a nucleus, which makes them eukaryotes. It includes animals, plants, protists, and fungi. Archaea also have cell walls that do not contain the peptidoglycan found in bacterial cells. It also lacks the cellulose that is found in plant cells, it also lacks the chitin that is found in fungal cells. Archaea are also…
