Answer:
Answer No 1:
The three ways evolution is determined to have occurred are:
A. Molecular similarities
C. Homologous structures
E. Fossil evidence
Explanation:
Since the theory of evolution became popular, scientists have been looking for similarities and differences among organisms so that they can compare which organisms have a more closer ancestor together as compared to other organisms. Scientists look for molecular similarities, such as the similarities in the proteins and other molecules to depict relations among organisms. Homologous structures is a common term in evolutionary studies in which organisms which are more closely related are known to be more similar. Fossil evidences also help a lot in evolutionary studies.'
Answer No 2:
The correct option is C. the most reproductively successful
Explanation:
Natural selection tends to favour the fittest organism. In evolution, 'the fittest; means the organism which have the ability to survive in an environment and to pass on its characteristics to its offspring. The organism which is more reproductively successful is considered to be more successful.
Answer:
True.
Explanation:
Mitochondria and chloroplast are the important cell organelle present in the organism. Mitochondria is used for the generation of ATP whereas chloroplast is used for the photosynthesis in plants.
Endosymbiont theory explains the evolution of mitochondria and chloroplast. According to this theory, the free-living prokaryotes taken from the inside of other prokaryotes and later evolve into mitochondria and chloroplast.
Thus, the correct answer is option (a).
