common household spices/herbs such as cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic‚ on the zone of inhibition in the Staphylococcus epidermis covered nutrient agar? Hypothesis: If 3 teaspoons of chopped cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic steep in half a cup of boiling water for 15 hours and then placed in nutrient agar covered with Staphylococcus epidermis (gram positive) bacteria for 24 hours (in an incubator)‚ garlic will have the strongest antimicrobial effect. This is because of allicin

I believe this was different depending on the bacteria because Chloramphenicol and tetracycline were the only organisms with growth on antibiotics agar. Yes‚ S. epidermis of antibiotics had all the six species effective. The difference between the gram-staining reaction microorganisms was lipopolysaccharide. S. epidermis had a gram-positive

Bizzozero ’s observations of these small dense nodules‚ subsequently named “nodes of Bizzozero‚” led him to the insightful interpretation of these structures as adhesive cell–cell contact points

The skin‚ or epithelial tissue‚ primarily consists of 3 distinct layers‚ the epidermis‚ dermis‚ and hypodermis‚ respectively. The epidermis‚ or outermost layer of the skin‚ is comprised of 5 layers: stratum corneum‚ stratum lucidum‚ stratum granulosum‚ stratum spinosum‚ and stratum basale. The skin is comprised mainly of squamous cells‚ basal cells‚ and melanocytes. Skin cancer is the most known form of cancer found in the United States‚ with over 54 million individual nonmelanoma related skin

Internal Structure Of A Plant PLANT CELL STRUCTURE Plant cells are classed as eukaryotes organisms‚ because they have a membrane enclosed nuclei and organelles. Here is a diagram of a plant cell;  Cytoplasm Most chemical reactions take place here. It helps the cell maintain it’s shape. Nucleus The nucleus has two main roles. Firstly it contains all the cells genetic information. Secondly it coordinates the cell’s activities‚ which include growth‚ intermediary metabolism‚ protein synthesis

The trichomeless root has a uniseriate epidermis‚ very thick layer of cortical parenchyma and well defined circular arrangement of vascular tissue in the middle. The dorsiventral leaf has a uniseriate epidermis‚ 3-4 layers of palisade‚ 3-4 layers of spongy mesophyll and in-between these are 5-8 layers of parenchyma where lateral veins lie.

The skin is made up of many layers. The outer layer is called the epidermis while the inner layers are called the dermis. Bullosa means blister and lysis mean breakdown. Therefore Epidermolysis Bullosa means the breakdown and blistering of the skin. Epidermolysis bullosa‚ EB‚ is a group of inherited genetic skin disorders
