Answer : The correct option is, (C) photosynthesis

Explanation :

Photosynthesis : It is a chemical process that occurs in the green plants. During photosynthesis process, carbon dioxide reacts with water in the presence of sunlight to gives glucose as a product and oxygen as a byproduct. In the photosynthesis reaction, carbon dioxide and water molecule are the reactants.

The balanced chemical reaction will be,

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

Whereas the combustion , decomposition and respiration are the chemical reactions in which the carbon dioxide is produced as a product.

Hence, the correct option is, (C) photosynthesis

Andy is studying the effect of sunlight on the growth of plants. He selected three identical plants with a height of 15 cm for t

Serggg [28]

Answer:

Analyze the data

Explanation:

A hypothesis is first coined before the experiment is conducted. Usually is a null hypothesis of no change. In this case it would most probably be ‘The is no relationship between the amount of sunlight that a plant receives and it's growth’

After the experiment, the observed data is collected and analyzed using statistical methods. The result of the data will determine where the null hypothesis will be adopted or rejected.

Research is done way before the experiment is conducted to provide headway.

Fire is an example of a living thing?

Alenkasestr [34]

Answer:

Fire Is A Non-Living Thing.

Explanation:

People sometimes think fire is living because it consumes and uses energy, requires oxygen, and moves through the environment. Fire is actually non-living. The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells.
