The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.
Organization of life, according to taxonomy, divides creatures into three domains: 
The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.

Models show systems that are large, small or complex.They make it easy for study through zooming in an area in a large system.They provide visual presentation of an object or a system that has been created through experimental data.
Explanation:
A model is a representation of an idea, a process or an object in a system used by a scientist to describe a phenomenon that is difficult to be experienced directly.The goal of a model is to ensure that the presentation is done in a logical and objective way.

Answer:
A. A segment of DNA molecule
Explanation:
(a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.
 
        
                    
             
        
        
        
Answer:
ATP and NADPH
Explanation:
The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
