Introduction: Our project is made from the raw materials such as starch‚ alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue. It doesn’t cost us too much time because we can make this in a short period of time. IV. Review of Related Literature:

` Study Guide for Exam 1 Chapter 1: 1. What is a “microbe”? What groups of organisms are included in this category? Microbes (microorganisms) are minute living things that individually are too small to be seen with the unaided eye the group includes bacteria‚ fungi‚ protozoa‚ and microscopic algae‚ viruses Only minority of microorganisms are pathogenic(disease-producing) 2.

plates were moved to a 4℃ environment to be stored until they were Gram stained using the process outlined in Friedman’s lab handout (Friedman 2017). Liquid cultures were made (from the streak plates stored) every seven days on the day before Gram staining. Observations of the milk samples‚ including pH‚ odor‚ and color‚ were recorded daily. The liquid cultures and plates were Gram stained every seven days. Observations of the Gram stained samples made under the microscope were

Corneal Ulcer (Introduction) The eye is one of the vital organs in a human being. As seen on figure 1‚ the eye is composed of many different parts and function. The cornea is a clear covering over the colored iris and the pupil of the eye. The function of cornea is to help focus light on the retina and protect the iris‚ lens‚ etc. so that the eye can see. The cornea is best to compare with a standard contact lens. Although‚ the function of a cornea is to protect from harmful microorganisms

Introduction This study approaches the understanding of the autosomal recessive “mini-muscle” phenotype in mice. Smaller body size and muscles as well as increased maximal oxygen intake are observed in mice with the “mini-muscle” phenotype. This observation raises an issue about why the selectively bred mice with the “mini-muscle” phenotype have reduced triceps and thigh muscle mass as they are able to cover greater distances; due to faster running speed‚ on an activity wheel compared to normal mice
