<h3><u>Answer;</u></h3>
It combines with water to form glucose.
<h3><u>Explanation;</u></h3>
- Photosynthesis is a process by which green plants make their own food by using solar energy from the sun, together with water and carbon dioxide.
- Carbon dioxide, water and light are all needed for photosynthesis to take place. During the process solar energy from the sun is used to convert carbon dioxide and water into the simple sugar glucose.
- <em><u>Substance A is the above question represent carbon dioxide which combines with water in presence of light to form simple sugars and oxygen gas.</u></em>
- The equation for the reaction is;
6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
The over-harvesting is one of the biggest threats to endangered species.
<u>Option: B</u>
<u>Explanation:</u>
- An organism or group of organism or species that is expected to reach extinction in the immediate future, either internationally or under a limited political authority, is understood as an endangered species.
- This may be at threat because of factors including habitat loss and poaching or over-exploitation.
- There are many species which are getting vanished day by day due to pollution or poaching, for an instance, pangolins, who have been hunted beyond he limits for their skin, scales, meat, and some body parts are utilized by people in making traditional medicine.
- The Indian and Philippine pangolin are listed as endangered while the Sunda and the Chinese pangolin are rated as critically endangered by the IUCN, which contributed to the Convention on International Trade in Endangered Species (CITES) prohibiting global trade that had something to do with pangolins or their components.
