Flagellum

One of his main examples comes from the bacterial flagellum, which features an extraordinary organic rotary motor. Behe argues that all parts are necessary for the flagellum to operate, so it is reasonable evidence to believe that the flagellum was intentionally designed by a higher power. Unfortunately, Behe is guilty of inserting personal bias to scientific interpretation, and he violates both…

light microscope because only the large organelles can be seen, such as: nuclei, chloroplasts, vacuoles. Most of the eukaryotic cells are motile. The three mechanisms that make them so are: flagella, cilia, amoeboid motion (Biology Department,2015).Flagellum has a whip-like structure which enables the cell motion. Cilia are a hair like structure which surrounds the cell and enables its movement. Amoeboid motion which is moving with false feet called…

They are unicellular organisms from the kingdom Protista. They move by a flagellum, which is located in the anterior end. They also contain a red eyespot at the anterior end that is able to detect light. Since Euglena lack a cell wall, they contain a pellicle composed of a protein layer. They usually live in quiet puddles or ponds…

Salmonella is very common, more than 1,000,000 people are infected annually(CNN). Salmonella is most common in South America due to a lot of meat and poultry consumed there. The salmonella bacteria affects the Digestive System, it also affects the vitals if it reaches the bloodstream. The digestive System is in charge of breaking down the food that is consumed, and if the Salmonella bacteria is in it it won’t be able to do its job. The Blood stream carries blood around the body, if salmonella…

Purpose: To observe different species of living protists in pond water under the microscope. Taking note of their size, movements, and characteristics to classify the different types of protists from applying previous knowledge of protists. Materials: The materials in this lab that will be needed are a microscope, slide, coverslips, a pipette, and a dish of pond water. Procedure: Prepare a slide by using the pipette to apply two drops of pond water on a slide and properly place a…

On Earth there are two major type of cells. Prokaryote and Eukaryote Prokaryote Cell – simplest and most ancient type of cells. There where the only form of life in Earth for billions of years before eventually giving rise to Eukaryote cells (2.7 billion years ago). If you take a look at Prokaryote and Eukaryote side by side, you can see a number of differences. To begin with, prokaryote cells are a lot smaller than Eukaryote cells and have a simpler structure. But bare in mind that this simple…

utility of anaerobic metabolism (Caprette, Page 1). Mitochondria is usually found to be in excess when you have a cell that use active processes. For instance, in flagellated protozoa or in mammalian sperm, mitochondria gather around the base of the flagellum or flagella (Caprette, Page 1). In cardiac muscle, mitochondria concentrate the contractile…

amount of time can make it hard to be certain to know if selection was actually involved in the evolution of a complex trait. Many creationists criticize selection saying it is powerless on the more complex traits. A simple example includes the flagellum on bacteria that assists in movement; it must have been created by something supernatural. The issue with this criticism is that there aren’t any traits that couldn’t have been impacted by selection. The fossil record shows the evolution of many…

The Blue Death is a mortifying illness that in most cases leads to death within a few days. Cholera is a severe dehydrating disease caused by vibrio cholerae, that affects victims worldwide. It is nicknamed The Blue Death, due to the extreme loss of fluids the body turns bluish-gray color. It is an acute diarrheal disease that causes severe vomiting and diarrhea. The first pandemic occurred in South Asia, in 1817 and continued to spread throughout India, China, the Middle East and Japan. It…

I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…
