The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Answer;
-Hydroxyl groups.
-They have multiple hydroxyl groups.
Explanation;
-Monosaccharides are the simplest form of sugars found in common food items such as honey, cane sugar, fruits. They are the building blocks of other carbohydrates (disaccharides and polysaccharides).
-The are formed by three elements and three elements only: Carbon (C), Hydrogen (H) and Oxygen (O). Monosaccharides have two broad classifications on the basis of the functional group present in them, that is; aldose (contains aldehyde group) and ketose (contains a keto group).
-Monosaccharides contain multiple hydroxyl groups, and are responsible for the hydrophillic property of monosaccharides allowing them to dissolve in water easily.
Answer:
Option (A)
Explanation:
In the primitive world, about 3 billion years back, there has been a sudden increase in the amount of oxygen gas in the atmosphere, and this was possible by the plants and other bacteria that carried out the process of photosynthesis.
The increasing amount of oxygen gas resulted in the formation of iron in the ocean water, where some of the available oxygen reacted with the dissolved iron and gave rise to the insoluble iron oxide. These insoluble iron oxide then sank into the bottom of the sea floor and over a due course of time, it gave rise to the formation of the banded-ironstone formation rocks (BIFs).
The rocks in the terrestrial environment also reacted with the oxygen and after the process of oxidation, rusting of rocks took place.
Thus, the correct answer is option (A).
Sorry for the other guy. He was rude. Here's the answer:
Animals excrete CO2 by cellular respiration. Since any living things besides plants can't break down CO2, it just gets put back into the environment. I hope I helped you :)
