Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

medicine works. Is it possible to create and transplant brain tissue to heal conditions like Parkinson’s disease? [Ask a MacArthur genius: Can feces fuel cars?] “My target was always to use this for Parkinson’s‚” he said. The disease‚ which affects about two of every 1‚000 people‚ is found in those whose brains stop producing dopamine. This neurotransmitter is like the brain’s messenger

11. Identify the four basic types of tissues and the functions of each tissue type. There are four different types of tissue. They are; nerve‚ epithelial‚ connective‚ and muscle. The nerve tissue is made up of neurons that receive and transmit electrical impulses‚ this is their function. There are several different types of epithelial tissue. First there is simple squamous epithelium tissue. This is a single layer of cells that is in the lining of blood vessels‚ the lining of the pulmonary alveoli

main tissues of the body. In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue. The first type of tissue found

do and don’t think of the banana. We hardly give much thought to the fruit that we nearly all eat everyday. The banana never fails us as a fruit; it is always (approximately) the same size‚ shape‚ and color. Yet‚ this is also the downfall our banana. The lack of genetic variation of our banana is what can wipe it out with a single strand of disease. Dan Koeppel‚ in his book Banana: The Fate of the Fruit That Changed the World‚ takes us through the history of the banana‚ from the very beginning of

bone tissue are created by the calcium phosphate that is part of the hydroxyapatite (as cited in Sheikh‚ 2015). Bone‚ as a living tissue has the ability to heal by itself but if the injury exceeds the limit of the bone to recover itself‚ it will not heal naturally (Rajendran‚ 2015). Current treatments have loopholes making it less effective and risky for humans. One of the most promising treatments‚ made possible by technological advancement‚ that can help solve bone problems is Bone Tissue Engineering

“A Summary of Wayson Choy’s I’m a Banana and Proud of It” In his essay “I’m a Banana and Proud of It” (from The Globe and Mail); Wayson Choy explains the reason why he is called a “banana”. Choy begins by expressing his love to his North American citizenship. He mentions that banana means “yellow on the outside and white inside” (365). In other words‚ Chinese born in North America behave and act like white people but still look like Asians. Regardless of this nickname Choy believe that it is “not

Scientists define culture as the total life way of a people‚ the social legacy the individual acquires from his group and can be regarded as that part of the environment that is the creation of man. Culture is what would make you feel shame or guilty. Culture manifests in beliefs‚ values‚ myths‚ legends‚ icons‚ language‚ dress traditions‚ customs‚ what is acceptable and unacceptable behavior‚ and even its unwritten rules in a particular area or group of persons. An example of how culture manifests itself
