Archaea

genetic similarities, and their biochemical similarities. The most popular form of classification system used by scientists is Linnaeus’s System of Classification, by which organisms are classified and grouped into 6 different kingdoms; bacteria, archaea, protista, fungi, plant and animal. By classifying organisms it provides scientists with an easy way to study organisms efficiently, and allows for predictions and knowledged observations. Knowledge about classification allows scientists to make…

According this article “Manure can spread antibiotic resistance” By Anne Ringgaard state that manure for the livestock if much greater if they do it the old way fashion where by artificial fertiliser instead of promoting in the soil with antibiotic resistance . It’s very new technology that were implanting recently and a lot of farmers are not really agreed upon, but scientific evidence finds out that soil fertilised with manure has more antibiotic resistance rather than soil that treated with…

There are about 100 million unique species on Earth. Living organisms exhibit unity because they use the same processes for seizing and storing energy, producing proteins, and passing on the information through genes from generation to generation. At the same time living organisms exhibit diversity because there are so many different species. All life on Earth is related because everything came to be from common origin yet beginning 4 billion years ago. Throughout the time living things have…

1. In England, “daddy long legs” refers to a long-legged fly, but the same name refers to a spider-like animal in the United States. How do scientists attempt to avoid such confusion? Illustrate these two organisms specifying which “daddy long legs” they represent and give the correct scientific name for each one. Tipula sp. Pholcus phalangioides Metaphalangium albounilineatum Image: http://www.burkemuseum.org/blog/myth-daddy-longlegs-kind-spider Scientists gave a different…

Dieting in adolescence due to weight dissatisfaction and insecurities on outer appearances is alarming as it is a growing concern for parents and practitioners. Of the various dieting methods, crash dieting is known to be a popular, yet dangerous fad among females, including young girls. Individuals are driven by celebrity-endorsement, media and social pressures to resort to crash diets despite lack of scientific evidence of efficacy, and studies of their mental and physical harm. What remains…

Define: a. Unicellular Organism Any living being consisting of a single cell. Most are invisible without a microscope but a few, such as the giant amoeba, may be visible to the naked eye. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi or yeasts. Some become disease-causing agents (pathogens). b. Colonial…

Prokaryotes There are two types of organisms based cell types: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into two parts: Bacteria and Archaea. Prokaryotes are much smaller than eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied…

Microorganisms can be classified as fungi, bacteria, protists, prions, archaea, and viruses. They are claimed as non-living. Microorganisms are known to be single-cellular, or unicellular. Unicellular protists are sometimes seen by the human eye, whereas multicellular protists are sometimes microscopic. They live in several…

The function of Eukaryotic and Prokaryotic cell components by FATIMA MOHIDIN Eukaryotic Cell Eukaryotic cells are cells that contain a nucleus and have membrane bound organelles they are multicellular cells and undertake reproduction by the process cell division known as meiosis and mitosis. There are 2 types of eukaryotic cell: plant and animal cells. They contain organelles such ribosomes, smooth and rough endoplasmic reticulum, mitochondria, nucleolus, centrioles, cell membrane,…

Bacteria and Typhoid Fever Bacteria are a single cell organism also known as a Prokaryote that have been around longer than Archaea and Eukarya. Bacteria appeared on Earth 4 billion years ago and are said to be the first forms of life (Nordqvist). The cell of bacterium does not have a nucleus and is without membrane-bound organelle. Bacteria can be rod, sphered or spiral shaped. Bacteria are the most plentiful organism on Earth; as well as being the most various. Humans and plants could not…
