<h2>
Answer:</h2>
During respiration in plants and animals, carbon dioxide is returned to the environment.
<h2>
Explanation:</h2>
Carbon dioxide is a dull gas with a thickness of about 60% which is higher than that of dry air. Carbon dioxide comprises of a carbon particle covalently twofold attached to two oxygen molecules. It is seen in atmosphere in traces.
When organism such as plant, animals, algae and other microorganism respires, it leads to return of carbon dioxide to the environment as it is the major compound formed due to the metabolic activity in them. Apart from this burning of fossil fuels and deforestation also act as cause of returning of carbon dioxide to the environment.

Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
As it moves around the
Earth, the side we can see gradually becomes more illuminated by direct sunlight. After a week, the
moon is 90 degrees away from the sun in the sky and is half illuminated, what we call "first quarter" because it is about a quarter of the way around the Earth.
It does not exist. Ca is 2+ and SiO4 is 4-, so it would in that case be Ca2SiO4, which does not exist either.
