days, it made them like water balloons. Soaking the eggs in vinegar for 2 days is very important in this lab. The reason why it is very important to soak the eggs in vinegar for 2 days is so that it removes the shell from the egg and you can rub the membrane to see the nucleus. The materials that you will need for the lab will be a raw egg that has been soaking in vinegar for 2 days. A red solo cup or a plastic cup, the difficulty that we had with this material was, my hand was too small to…

We have been learning about cells for a long time in science class, and now is the time to put all the hard work and studying to the test. Have you noticed how much a house and a cell are so much alike? If your answer was no then you're about to ‘cause this is: House Theory to Cell Theory Written by E.B. Powers I sat in my room thinking to myself about the cells that we have been learning about in school. While I was thinking, I got really hungry, so I went to my kitchen. As I was making my…

Ankyloglossia, or commonly referred to as a "tongue tie", is a condition seen in newborns when the lingual frenulum (the connecting membrane that supports the tongue) is short. The act of cutting the frenulum is called a lingual frenectomy. Two types of frenectomies exist. There are labial frenectomies (membrane is attached toward the lips) and lingual frenectomies (membrane is attached at the tongue). A labial frenectomy is performed when the frenum pulls on the gum tissue.. A tissue pull can…

whereby soil acts as the inoculum, the nutrient-rich anodic, and the proton exchange membrane (or PEM). An inoculum is the microorganism used in the placement of something that will grow or reproduce, a nutrient-rich anodic is the positively charged electrode that attracts the negative ions in a circuit or chemical reaction which is high in nutrients, and a proton exchange membrane is a semi-permeable membrane made from an ion containing a polymer and designed to make protons while being…

They account for 3% of the plasma membranes weight and are essential in lubrication and protection of the cell. Carboyhydrates are apart of complex molecules such as proteoglycans, glycoproteins and glycolipids. The carbohydrates in these molecules extend beyond the outer surface of the membrane forming a layer known as the glycocalyx. This coats the cell and acts as a first layer of defense as the glycocalyx allows…

hand, when 1.20 M of Sucrose Concentration was emerged in water for 60 minutes and pulled out, its mass went from 6.48g to 9.03g.. Osmosis is the net flow of water through a semipermeable membrane. It is basically a unique form of diffusion where the water is the only molecule able to diffuse through the membrane (Wood-Robinson, 2001). The mass of the 1.20M sucrose concentrated dialysis tube became turgid because the…

delivery by altering the internal factors of PH, osmolarity and permeation enhancers, the researchers (Yangfeng, Zhong, & Chow, 2008) show how the factors of PH, Osmolarity and permeability enhancers can affect the permeability if the lipophilic membrane and the ß-blockers are used. The identified factors are the important factors in drug design and formulation. The effect of the stated factors is also evaluated in the research by (Hanne & Rassing, 1999), so hey evaluate the response of TR 146…

involving loss of polarization of epithelial cells that normally interact with basement membrane through its basal surface. These cells endure biochemical changes and transform into mesenchymal phenotypes (Kalluri and Weinberg, 1997). This transformation imparts increased migratory potential, invasiveness and renders the cells resistant to apoptosis. The completion of EMT is involved in disruption of basement membrane through which these mesenchymal cells migrate to underlying tissues (Kalluri…

Compare and Contrast different Tissue types – M1 Comparison between Connective Tissue and Epithelial Tissue Similarities: There are many similarities between connective and epithelial tissues. One of which is that both the connective and epithelial tissues have at least 2 layers. A similarity between the connective and epithelial tissues related to the organelles present and its functions is that they both have nucleus and mitochondria, so both need the production of energy to function and…

Cell to Cell Communication Two or multiple cells who are in a close radius have the capability to communicate with each other through the plasma membrane. Cells send signals through steps of signal transduction pathway. Cells communicate through chemical messages long distance and in a short radius. Different Types of Signaling In long distance and short distance signaling there are many different types of signaling used for communication between cells. The local communication is done through…
