If the compound is effective against bacteria at a certain concentration‚ no colonies will grow wherever the concentration in the agar is greater than or equal to that effective concentration. This region is called the "zone of inhibition." Materials and Equipment: • Samples of: Scalp‚ Ear‚ Feet‚ Nose‚ Arm‚ Underarm and

Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone has a

Summary Richard Preston’s Hot Zone is a horrific narration of the origin of filoviruses and their encounter with humans. These viruses include Marburg virus (MARV)‚ Ebola virus (EBOV) and Sudan virus (SUDV). They are also known as Biosafety Level 4 agents because they are extremely dangerous to humans and have no treatments or cure.

The concentric zone model was among the early descriptions of urban form or Cities. Originated by Earnest Burgess in the 1920’s‚the concentric zone model depicts the use of Urban land as a set of concentric rings with each ring devoted to a different land use. The model was based on Burgess Observation of Chicago during the early years of the 20th Century. Major routes of transportation emanated from the city core‚ thus making the central business district the most accessible location in the city

Abyssal Zone Steven Jevan 10.2 Located deeper than 2000 meters underneath the ocean surface‚ lies a biome that we have barely seen and realize. This unbelievable and incredible biome is called the abyssal zone. With a depth reaching down to 6000 meters‚ it is impossible to inhabit this biome. Conversely‚ certain organisms have managed to keep their survival in this very biome through particular processes. Initially‚ the abyssal zone and the living organisms inside it‚ suffers

Crumple Zone I choose to look at the crumple zone in cars for my technological device and briefly touch upon seat belts in cars and air bags. The crumple zone in my own words is a zone built in an automobile to compress when an accident occurs. This was built to absorb “deformation” energy from the impact. The other reason it was built‚ which is more common is to reduce the deaths in car accidents. Crumple zones are mostly located in the front of a car and this will absorb the energy from “head

The Intertidal Zone The intertidal zone is the area of the sea floor that is uncovered and recovered by the tides. At high tide‚ the intertidal zone is submerged beneath sea water and at low tide it is exposed to air. There are two main types of intertidal zones that experience this daily change‚ the sandy shore and the rocky shore. Each has different characteristics and special organisms that survive there. These different species tend to inhabit different zones in which they can handle but there
