Plants showing hydrotropism grow in response to water.
Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
Hello to answer your question.
A is correct
But more likely forest fires would be the culprit because the trees produce O2
so when the are burnt, it would be like everybody o this earth breathed out at once causing CO2 to be released in to the atmostphere in a big burst
