How could you test to see if soil temperature was responsible for the variation in flower color

Gelneren [198K]

Answer:

by conducting scientific experiment.

Explanation:

The effect of temperature on changes in flower color can be tested by performing scientific experiment. The temperature range will be independent variable and the variation in flower color will be dependent variable.

In this way the experiment will be done to see the result in order to prove the hypothesis.

The complete oxidation of glucose (C6H12O6) to carbon dioxide and water in aerobic respiration consumes how many molecules of ox

LekaFEV [45]

Answer: The correct answer is Option c.

Explanation:

Combustion reaction is defined as the chemical reaction in which an organic compound reacts with oxygen gas to produce carbon dioxide gas and water molecule.

This reaction is also known as oxidation reaction.

The chemical equation for the combustion/oxidation of glucose molecule follows:

$C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O$

By Stoichiometry of the reaction:

1 molecule of glucose reacts with 6 molecules of oxygen gas to produce 6 molecules of carbon dioxide gas and 6 molecules of water.

Hence, the correct answer is Option c.
