Exercise 14: Unknown Identification Lab Report The purpose of the study was to identify the unknown bacterium using various biochemical tests in addition to using scientific methods in determining the outcome of the hypothesis. Each biochemical test will help determine the bacteria based on specific characteristics of each organism. I was giving unknown number 232. The first procedure that needed to be done after obtaining unknown bacterial mixture was to isolate the two bacteria in a pure culture using the streak plate method described in Microbiology Laboratory Manual Eight Edition. The material used was trypticase soy agar (TSA) plate, nutrient plate, starch agar, hydrogen peroxide, iodine reagent and microscope.
Adetutu Okupe Bio 3800 Dr. Poole December 4, 2015. Writing Assignment 4B Patient: Hello Doctor, my name is Keisha Cole. I have been having some flu like symptoms lately and really don’t understand this symptoms. Dr. Oz: Hello Keisha, I understand your frustration and I am here to help you understand what is actually going on in your body.
DIY - What Is Life? How can you determine whether something is alive, dead, or non-living? Whenever we speak of life, we must think in terms of cells.
When Henrietta’s case is revealed to people, their first response is usually: “Wasn’t it illegal for doctors to take Henrietta’s cells without her knowledge and consent? Don’t doctors have to tell you when they use your cells in research?” Well...no. At least, not in the 1950s to the early 21st century. People are often confused on how they should feel about this situation, which is understandable.
The Dermis is the second layer of skin. It is located below the Epidermis and contains our hair follicles (which sprout on the Epidermis). The Hypodermis is the lowest and largest layer, containing fat and connective tissues.
Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached.
They are made of pericytes and an endothelial layer, also possibly a basement membrane. The reason for this thinness is to allow for the exchange of gases and nutrients to flow in and out of the
The dermis which is the second layer is more active and hosts capillaries, blood vessels, elastin and also fibroblasts. Dermis also has certain polysaccharides like glycosaminoglycans which keep the cellular activity towards the
The effects of alcohol on Biological Membranes. Introduction In this experiment it will be analysed the damage alcohols can have on biological membranes. Membranes are made up of lipids and proteins. Membranes usually help maintain the balance in a cell as it holds all the cellular materials.
In case you are unaware of the importance of these layers of skin, let me inform you. The stratum basale is known as the deepest layer of the epidermis, which allows it to be attached to
HOW THE SKIN PROTECTS THE BODY The skin plays a major part in regulating human body temperature and protecting the body. It consists of two layers: the outer epidermis and the inner epidermis. Beneath these layer is the adipose tissue, which contains fat-rich cells. PROTECTION:
Fix or replace damaged tissue; biology has always been the main concern for scientists. Today, the most important instrument for tissue engineering scientists to produce replacement tissues and implants to repair or replace damaged tissue. Tissue engineering is generating a new field of study in which the principles of engineering and biology to correct the damaged tissue, uses and can renewal, operation and maintenance of tissue healing. In order to use an ideal scaffold Tissue engineering should have features such as non-toxic Cell and tissue properties to be fit.
Did you ever read fairy tales when you were a child, and wonder how cats and mice became enemies? Well, you can find the answers in the text “Cat and Rat: Legend of the Chinese Zodiac” and “How Cats and Mice Became Enemies.” The two of these stories share almost the same conspiracy, with their own contradictions. With these two testimonies there will of course be similarities such as, the two main characters being friends, the cats falls asleep the trip, the cat subsides into the water, also the two stories take place in China. In the same way that the tales being similar, there will of course be disagreements, including, the two settings have difference race destinations, the rat and the mouse have different intentions, and finally the vessel the
The human body is an amazing thing made up of many different parts. These parts are cells, tissues, organs, and organ systems. For starters, one type of cell makes up one type of tissue. Next, two or more types of tissues make an organ. Then, a few organs working together make an organ system.
The epidermis is the layer of skin that we can see. It varies in thickness. The thickest layer is on the soles of the feet and the palms of the hands. The thinnest layer is on the eyelids and nipples. The cells on the surface are constantly coming off (shedding) this is known as desquamation.
