Use model 1 to determine the two types of light also called electromagnetic radiation emr that are radiated from the sun and penetrate the greenhouse glass

ultraviolet light and visible light.

Explanation:

Doing some research I managed to find the image of the model 1 to which this question refers.

You can see the model attached to this answer.

The model clearly states the two types of light (electro magnetic radiation EMR) radiated by the sun and that penetrate the greenhouse.

Those are:

- Ultraviolet light, and
- Visible light.

Those forms of lights that penetrate the greenhouse generate heat which is infrared light.

The infrared light (heat) cannot penetrate either the glass of the greenhouse or greenhouse gases (in the atmosphere) but they are trapped. This is the cause of the increase of temperature known as greenhouse effect.

The main gases in the Earth's atmosphere that trap the infrared light (heat) are: metane (CH4), water vapor (H2O), and CO2. They are called greenhouse gases.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
