Answer:
The answer is letter a, Deductive Reasoning.
Explanation:
Reasoning- this is the act of thinking about something in a logical and sensible way. There are many types of reasoning but we'll focus on <em>deductive reasoning. </em>
Premise- a statement in an argument that provides reason or support for the conclusion.
Conclusion- a judgment or decision reached by reasoning.
Deductive Reasoning- this is also known as <em>"deductive logic." </em>This is the process of reasoning from one or more statements in order to reach a conclusion. It moves from generalized principles that are known to be true to a true and specific conclusion.
In the example above, the generalized principle is "All prokaryotes lack a well-defined nucleus." The premise is "The newly discovered cell has no well-defined nucleus." The conclusion is " Therefore, the newly discovered cell is a prokaryote."
Thus, the example above follows the deductive reasoning pattern.
<span>The correct answer is option A. i.e. Renewable source.
Using biofuels instead of fossil fuels because biofuels are renewable is am an example of Renewable sources. Biofuel is mainly developed from trees matter - leaves or decayed parts. And trees can be regrown and reused again So, it is a renewable source.</span>
Answer: The criteria to place elements into groups and periods lies in their atomic number
Explanation:
As we know that period is the horizontal rows of elements in the periodic table and groups are vertical column of elements in the periodic table.
In a period we place those elements that have same number of shells and in a group those elements are placed that have different number of shells and the number of shells increases from top to bottom in a periodic table
For example
Sodium having symbol Na, atomic number of sodium is eleven it's electronic configuration is 1s2,2s2,2p6,3s1, next to it in a period is places potassium having symbol,K, it's electronic configuration is 1s2,2s2,2p6,3s2.
Sodium and potassium both r placed in a period not in a group because both of these have same outer most shell, only the number of electron in outer most shell varies.
Photochemical smong result from the interaction of pollution in the presence of sunlight. The photochemical smog is result of the <span> chemical reaction in the air between the sunlight, nitrogen oxides and volatile organic compounds.
</span>It is noticed as a brown haze above cities. <span>The negative effects are: production of chlorofluorocarbons (CFCs) increased UV radiation, irritation to the eyes, nose, and throat. </span>
