To be able the students to differentiate and observe what the branded antiseptics and disinfectants can do. Methodology Materials and Procedures In order to start the activity‚ we cooked agar where we cultivated the bacteria (Staphylococcus epidermis). After plating and cooling the agar inside the petri dish‚ we foreplate the bacteria by using a cotton swab. We prepared two (2) petri dishes. One is for the bacteria and the other one is by swabbing the cotton swab to any surface and then foreplated

It is a cancer that forms in epithelial cells that produces fluids or mucus. Most types of cancers like breast‚ colon‚ prostate are adenocarcinomas. Basal cell carcinoma : It is a cancer‚ that begins in lower layer ( basal / base layer ) of the epidermis‚ which is the person’s outer layer of the skin. Squamous cell carcinoma : These cancers are formed in the squamous cells‚ which are epithelial cells that lies just beneath the outer surface of skin. These squamous cells line the outer side of the

Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so

Chapter 37: Water and sugar transport in plants Water moves from areas of high water potential to areas of low water potential. Water’s potential energy in plants is a combination of (1) it’s tendency to move in response to differences in solute concentration and (2) the pressure exerted on it Plants do not expend energy to replace water that is lost to transpiration when stomata are open and photosynthesis is occurring. Instead‚ water moves from soil and roots to leaves long a water potential

Organization of the human body Human anatomy and physiology – study of the structure and function of the human body. Anatomy- the scientific discipline that investigates the structure of the human body. Physiology – The scientific discipline that investigates the process of functions of living things. 6 Structural levels 1. Chemical level – atoms combine to form molecules 2. Cell level – Molecule form organelles 3. Tissue level – similar and surrounding material make up tissues

Civil Rights Argument In 1959‚ Clifton Davis was denied the privilege to accompany his white friends to Glen Echo Amusement Park based on his epidermis hue. Black and white are like yin and yang‚ they are the antitheses of each other: but amalgamated they are coequal. Glen Echo should change their policies and allow Clifton and colored people to enter the park. This act was wrong and went against important rationals. This act went against three rationales. One rationale was the Declaration
