Fuel cell

alternative resources that we use today include nuclear energy, hydro energy, wind energy and hydroelectric energy. Alternative resources is termed to configure the differences between fossil fuels and how they contribute to society. These forms of energy are not traditional forms from which you get out of fossil fuels, but they prove to be cleaner and much safer for our environment. Renewable energy sources create energy in many different forms and ways. For example, the way that…

and sheets of semiconductors (SEIA). Energy from the sun excites electrons and causes them to “free themselves” and run through a circuit, powering electronic devices along their way (SEIA). Wind energy is generated in a close fashion to how fossil fuel power plants gather their energy. In coal fired plants, large fires cause the expansion of air. This causes a turbine to spin and generate energy. In the unmistakable pinwheel design of a wind turbine, air rushes through the blades of the…

efficiently change the internal organization of the cell, and capture organelles through the cytosol. Intermediate filaments are made up of the protein keratin. Their primary function is to strengthen the internal structure of a cell. Microfilaments are the smallest among the three cytoskeletal filaments. They consist of protein actin. Microfilaments are dynamic structures that can rapidly disassemble or assemble themselves, and thus microfilaments enable the cell to move efficiently. Cilia and…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…

Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

within a cell, they can be expressed in response to external stimuli. This external stimuli can be sub lethal heat shock (SLHS) hence the name heat shock proteins (Baneyx, F. 2008), this stimulus causes more of the proteins to be produced (Pugsley, A. 1989). In addition to being expressed due to SLHS they can also be expressed in response to amino acid analogs, heavy metals…

In the case of a missing limb, the scientists would take stem cells from the patient and us it for the base of the new limb. If Humans mastered cloning then they could use that technology and the patient’s stem cells to construct a new arm, leg, ear, or whatever was missing without worrying too much about the patient’s body rejecting the foreign limb. In the case of organs the process would…

to change into these protective suits so we would be kept safe from any harmful substances. We were all told that we would be put into two groups the A and the B group. We would all be put into a Eukaryotic Cell if the machine worked to get a closer look at the organelles in a Eukaryotic Cell. I was put into the A group along with another girl who looked about 16. The B group had a boy who looked about 14 and a girl who looked about 15. I guess the age varied between all of us because I am 17.…

a virus vector. Then, the vector binds to the cell membrane. After the vector binds to the cell membrane, a vesicle forms around the vector as it enters the cell. Thereafter, the vesicle breaks down, releasing the vector. Then, the vector inserts the DNA it contains into the cell’s nucleus. The cell makes a functional…

Photothermal therapy would support the nano-carriers with the RNA by creating a pathway through the cell to the nucleus. In which the nanomedicine will introduce foreign RNA to modify the genetics while the reactivity of the heat from the P.T therapy would enhance the strength of the nucleotide. There are two methods for this drug delivery. One takes…
