1. What is the Use of the Ozone Layer in the Earth's Environment, and Why is it Important?
Answer: Ozone is one of the most important layers of our earth's atmosphere for many reasons. Ozone is a natural process for all types of life forms. In addition to this, it is the layer of the atmosphere that protects the earth from the sun's harmful radiation. If the ozone is not present in the earth's atmosphere, there won't be any life on earth as the sun's heat waves can easily destroy all the life forms and evaporate all the water present in the sea.
Thus, if there's a slight change in this layer's size, it will bring a drastic change in the lives of people. Furthermore, the snow that is melting on the north and south pole of the earth is happening because of the ozone layer's holes.
2. What is a Dark Reaction in Plants? Does it Happen Without Light, and Does Photosynthesis Always Need Light for the Reaction to Take Place?
Answer: Dark reaction is the process of photosynthesis, which happens in the absence of light, i.e., it happens in the night, but it is also the reaction that is happening simultaneously with light reaction. It's a chemical process that happens in a plant that does not need light. Moreover, this reaction is based on the enzymes reacting with each other. As a result, even if there is no light, it will still take place. Also, when it comes to photosynthesis, it can only be done when sunlight or artificial light is triggering photosynthesis.
