Answer: light reaction produces oxygen and water as we know the general importance of oxygen and water they are useful for organism to survive if plants do not produce oxygen then how could we get oxygen from the environment
Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories.
There are 5 main steps in hypothesis testing:
State your research hypothesis as a null and alternate hypothesis.
Collect data in a way designed to test the hypothesis.
Perform an appropriate statistical test.
Decide whether to reject or fail to reject your null hypothesis.
Present the findings in your results and discussion section.
Though the specific details might vary, the procedure you will use when testing a hypothesis will always follow some version of these step

The Lewis structure depicts the number valence electrons surrounding an atom. These are the electrons present in the outer shells which can participate in bonding with another atom or remain as non-bonding (lone pair) electrons.
In the given example there are 7 dots or 7 electrons surrounding a Cl atom. This corresponds to 7 valence electrons with a configuration that can be given as: s²p⁵ and specifically, 2s²2p⁵
The answer for that is 16, math right?
Answer:
b
Explanation:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds.
