Green Tea has proven to be the most popular drink in the world. In the article, the writer mentioned that people that consumed regularly green tea have a lower risk of having stress, anxiety, and depression. An example of green tea referred to in the article was Camellia sinensis, this type of green tea is less fermented, and as a result, it contains more antioxidants. A great benefit of green tea are the various effects of prevention of tooth decay, inhibition of high blood pressure, cancer prevention, and others. Another component that green tea contains is caffeine, which can cause increased of alertness, increased stamina, and hangover prevention. In addition to her article, she mentions green tea can also help stabilize blood pressure and cholesterol levels. She finalized by recommending drinking a few cups of green tea every day to experience the health benefits that green tea can offer.    

Cell and Molecular Class

Cell and Molecular Class

The molecular cell class it focused on the study of cellular process or the basic unit of life. The information provided its link with biochemistry, immunology, genetics, and microbiology. In detail cell biology is the study of different structures and functions of the cell. Throughout the semester, the class will emphasize on the following: Organization of organelles, life cycle, cell interactions with the environment, metabolic processes, physiological properties, signaling pathways. The first two weeks in the class we have covered microscopic and differentiation between prokaryotic and eukaryotic cells. As a class, we are hoping to learn how cells work and this essential to understand diseases and disorders in the human body, to successfully apply them in our professional careers.

Microscopes Techniques

• EM microscopy- Is the use of an electron microscope that are used study ultra structure inorganic specimens such as: microorganism, cells, biopsy, metals, and large molecules. The microscope uses a beam of electrons as light. The wavelength that it produced it's about 100,000 times smallest than a light microscopes. 

      

• Light microscope- Also known as the optical microscope, this type of microscope uses visible light and lenses to visualize images of the samples. The optical microscope has being the initial invention to bring out some other microscope that as well uses light. For example: fluorescence microscopy, dark and bright field, digital microscope. 

• Force Spectrum microscopy- It's the application technique of Brownian motion, which is the motion of particles that are suspended in fluid. This can amplify the magnitude of random forces that can interfered with the oscillation frequency of particles when is viewed from a spectrum microscope.

• Polarizing microscope- Another name for the polarizing microscope is petrographic microscope and mainly used for geological specimens, although this microscope has being a great used in medicine and biology. The main component that differentiates from other microscopes is that uses polarized light, which are light waves traveling in one direction.
