Biol 2215 Assignment 1

There are four main characteristics of the scientific method: observation/measurements, make an assumption, test the assumption, and revise the assumption. The first stage we make an observations. For instance, I notice that my peppers in my garden are not growing well. I am going to assume this is because I did not water that area well enough. So I am now going to test my assumption. This is done by watering the peppers in my garden more frequently. Lastly, I am going to see if my assumption was correct. If my peppers only needed more water, they will begin to grow more rapidly. It is also possible that my assumption was wrong, and that my peppers were getting enough water; however, there could be something wrong with the soil, temperature, etc. These are the four main characteristics of the scientific method; it is important to note that our assumptions sometimes be wrong, thus it is always important that we test our assumptions to make sure we are correct.

Scientific Method: The scientific method is a method or procedure that uses precise measurements, predictions, and data to answer questions.

The scientific method is used during experiments to find a conclusion and or reason as to why an event or something happens.

Most micro-organisms need most of the things you and I need to flourish and grow - moisture, warmth and a source of nutrition - some (usually the most dangerous such as those responsible for some types of gangrene) can do without oxygen (anaerobic bacteria). They need a mode of spread (usually the unwashed or poorly washed hands of people or badly cleaned equipment/facilities or badly stored food) and a vulnerable person to invade.

A patient with poorly controlled Type I diabetes has blood drawn and finds that the pH of his blood is 7.1. The normal pH of blood is 7.4. The patient's blood [H+] is

Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab.

Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to assess the health of ecosystems based upon their biodiversity. Then, you will utilize this information and your eScience lab kit to complete Demonstration 1 and Experiment 1 on the Week Three Lab Reporting Form. Make sure to complete all of the following items before submission:

Prokaryotic: (single cell)The plasma membrane encloses the cell, regulating the traffic of materials into and out of the cell, and separating its interior from the external environment.

2. Choose 1 of the actions listed at the beginning of this activity. How does the process of cooperating, communicating, and thinking like a scientist relate to that action?

If a hypothesis is verified using experimentation then what might be the next step in the scientific method?

The broad- spectrum antibiotic kills any and all types of bacteria within the body. Since bacteria in the large intestine is being killed, there will be a reduction in vitamin K that is being released inside the body. Since vitamin K is important in the formation of prothrombin, with the reduction of vitamin K it will reduce prothrombin in the blood which makes it harder for the blood to clot. This will result in more of epistaxis (nose bleed).

SCIENTIFIC PROCESS- the scientific process is a way to make sure that your experiment can give a good answer to your question. We use observations, hypotheses, predictions, experimentation, and conclusions.

The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments, in order to try to construct a reliable, consistent, and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First, the scientist must observe the phenomenon of interest. Next, the scientist must propose a hypothesis, or idea in which the experiments will be based around. Then, through repeated experimentation, the hypothesis can either be proven false or become a theory. If the hypothesis is proven to be false, the scientist must reformulate his or her ideas and come up with another hypothesis, and the experimentation begins again. This
