Answer:
Explanation:
The six Kingdoms are: Archaebacteria, Eubacteria, Fungi, Protista, Plants and Animals. -Organisms are placed into these categories based on similarities or common characteristics. Some of the characteristics that are used to determine placement are cell type, nutrient acquisition, and reproduction.

Answer;
-Structural isomers.
Explanation;
-Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.
-Structural Isomers are molecules which have the same molecular formula but have different connectivities. That is; the molecules have the same molecular formula, but their atoms have different arrangements or bonds.
-For example, butane and isobutane are structural isomers, also called chain isomers. In chain isomers, the carbon atoms are connected in different orders. Isobutane and butane have a molecular formula of C4H10.
3-PGA is the important metabolic intermediate in light independent reactions of photosynthesis.
PGA
<u>Explanation:</u>
Light-independent reaction in photosynthesis is called Calvin cycle and the reaction doesn’t directly require sunlight. But it still needs the products of light reaction. In light-independent reaction carbon dioxide is fixed from inorganic form into an organic form.
In the fixation each molecule of carbon dioxide reacts with RuBP and forms two molecules of 3-PGA at a time. The reaction is catalyzed by the enzyme RuBisCO. Since 3 molecules of RuBP are involved a total of 6 molecules of 3-PGA will be formed in fixation.
Here the 3-PGA is the intermediate and in the next stage it will get reduced to G3P(Glyceraldehyde -3 phosphate).
The invention of microscopes changed the way cells were able to reproduce.
