What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012). MICROBIOLOGY: A SYSTEMS APPROACH, THIRD EDITION.
More generally, organisms that feed on autotrophs in general are known as primary consumers. d) A consumer is a person or group of people that are the final users of products and or services generated within a social system. e) Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life. f) Fauna is all of the animal life of any particular region or time. g) biological environment includes the influence of all biological factors such as warmth, moisture and humidity, but also the plant ecosystem in which the animal lives and the associated populations of vertebrates and invertebrates that may compete for food and space, and may also act as reservoirs for infectious
If I change _____________________________________________ then the fish will __________________________________________________________________________. c. If I change _____________________________________________ then the fish will __________________________________________________________________________. Design your experiment: 4. Your control group is the “group” of fish that you are keeping in their “normal” environment. How many fish will you measure initially?
Lab 1 – Introduction to Science Exercise 1: The Scientific Method Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below. QUESTIONS 1.
Finding Nemo assignment 1. What is Nemo and Marlin’s environment? Their environment is the ocean and the salt water habitat. 2. What is their habitat and niche?
Akella Turnbull Date: February 2, 2015 Lab Partner: Shubh Rana South Street Seaweed Seaport Lab Summary: In this lab, we were able to make our own tinctures of iodine by extracting iodine from a Japanese seaweed, referred to as Fucus seaweed. We were able to conduct a hot water extraction from this seaweed in order to isolate the iodide, which is a solution that can be used to manufacture a pharmaceutical product. In order to prepare a tincture of iodine for testing we had to use a balance, ignite a Bunsen burner, and heat and filter a solution. In doing so, we had to prepare 6 grams of dry seaweed by cutting it into ½ inch pieces and placing it into a beaker filled with ¾ distilled water. Then after agitating the seaweed to remove monosodium glutamate and pouring off the water, 40 mL of distilled water was added to the seaweed and heated.
Exercise 1: Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of ppm—or parts per million. Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water from which the sample was taken; finally, answer the questions below.

The Rideau River Ecosystem and Food Web Team A BIO/101 Brian Fox The Rideau River Ecosystems are biological populations of interacting organisms and their physical surroundings. Many are areas of lands that have changed due to the nearby water currents. These areas of land are home to many animals and plants that have adapted to survive. Each individual ecosystem is comprised of different features that make it conducive to certain plants and animals. That means each ecosystem is unique.
Include at least 4 organisms and be sure to identify which organisms are the producers, first level, secondary level, and tertiary level consumers. In addition, state the nutritional modality of the consumer (herbivore, carnivore, etc.) (8 pts.) 2) Make a list of as many organisms you can identify that contributed to a balanced ecosystem in and around Pride Rock. Using the characters from the movie, draw and label a complete food web, explain how they are connected, and categorize the organisms by their nutritional modality.
Answer = The dissolved oxygen (DO) is oxygen that is dissolved in water. The oxygen dissolve by diffusion by diffusion from the surrounding air aeration of water that has tumbled over falls and rapids and as waste product of photosynthesis, fish and aquatic animals cannot split oxygen from water (H2O) or other containing compounds. Only green plants and some bacteria can do that through photosynthesis and similar processes. (www.lenntech.com/why_the_oxygen_dissolved_is_important 3. Construct a hypothesis – Based on your observation in question 1 and your background research in question 2, develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of
