1. Nearly all the environment contains microorganism whether it is soil, air, water or any other surface. They have the ability of live in the extreme conditions.

There are different forms of bacteria found at different places. Some of them are thermophiles that at found in extremely hot conditions such as thermal vents.

The organism like Psychrophiles are the microorganisms that have the ability to survive at lower temperatures. Example: bacteria found in polar regions.

2. A culture can be defined as a pure culture if it has an unadulterated species of bacteria. It has no contamination and if a small inoculum from the pure sample is streaked on a plate then a pure culture of the sample is obtained.

This should be done in an aseptic condition so that the bacterial species should be free from contamination.

VMariaS [17]

The best answer is (1)

Fossil fuels are commercially available as an energy source.

They are very easy to find. More and more extractions of fossil fuels is going on everyday. With advancement in science and technology, the refineries and extraction procedures have improved a lot. This makes their availability even better.

Fossil fuels are also easily combustible. Most combustion engines need to be powered with little amount of fuel to produce large amount of energy. Very large amounts of electricity can be generated from fossil fuels.

Using the specific steps of the scientific method, tell me how you would use the scientific method to solve this problem: A fami

Nastasia [14]

Answer:

Explanation:

Scientific Research is a method used in the construction and testing of a scientific hypothesis.

It has six steps that can be used in solving questions ask or observations made which is A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.

Steps to follow:

Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked

Ask a question : The question is

which is more effective in conserving water a misting shower head or regular shower.

Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked

Example: Null hypothesis: Mistling shower conserves more water than shower head

Alternative: Mistling shower conserves less water that normal shower.

Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference

Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.

Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
