You have to find the similarities and differences of intrusive and extrusive igneous rocks for the first question. The second one requires you to find out coarse-grained rocks are formed, the third is asking how igneous rocks are classified according to its structure, like the construction of the rock(what it is made up of). The fourth is asking you how fine grained-igneous rocks are made basically, the fifth is asking you how do igneous rocks with that glossy fine stain, how are they made.
<span>The hypothesis has to survive all attacks on it and continue to provide the best known explanation of the known data.
In the scientific method, there are several steps towards the creation of a hypothesis and eventually a theory.
1. Gather data.
2. Construct a hypothesis that explains the data. This hypothesis should be capable of being disproved and should be capable of making predictions.
3. Gather more data. DO NOT cherry pick only that data which supports the hypothesis . If data is uncovered that contradicts the hypothesis , revise or replace the hypothesis.
4. After the hypothesis has survived all attacks on it and is the best known explanation of the data, then it becomes a theory.
5. Note, data collection continues after the hypothesis became a theory and if new data is discovered that is in conflict with the theory, then the theory is modified, or discarded in favor of a new hypothesis or theory.</span>
Answer:
The correct answer is: Actinobacteria
Explanation:
Actinobacteria is a phylum of the Gram-positive aquatic or terrestrial bacteria that have high concentrations of guanine and cytosine in their DNA.
These bacteria are economically important to the human beings as they produce bioactive metabolites used in producing medicines and are also responsible for the <u>decomposition of organic matter of dead organisms in the soil.</u>
<u>Therefore, Actinobacteria will be the best bacteria to be used in the laboratory.</u>
C. Grind the rock salt into smaller pieces.
increased surface area by decreasing particle size will increase the rate of dissolution
Answer:
The temperatures around the world
