Although he could not actually see into cells, he deduced from his results that each of an organism’s traits is determined by two factors (alleles). Long after Mendel’s work, microscopes were improved and scientists observed that chromosomes in the nucleus occurred in matching pairs. It is now accepted that the two alleles for each trait are located on homologous chromosomes. What does this demonstrate about science?Advances in science may result from new interpretations of previous work.Improvements in equipment and data gathering can disprove previous conclusions.Earlier scientists did not have the proper equipment and materials to make their conclusions.Much of early scientific research was faulty because the earlier scientists did not practice the same data-gathering practices as modern scientists.SC.6.N.3.3 Give several examples of scientific laws.Cognitive Complexity/Depth of Knowledge Rating: LowDue to gravity, if you dropped an object on the Earth the object would move toward the center of the Earth is an example of?Ascientific theoryCscientific experimentBscientific lawDscientific truth SC.6.N.3.4 Identify the role of models in the context of the sixth grade science benchmarks.Cognitive Complexity/Depth of Knowledge Rating: ModerateA timeline of some models of atoms throughout history is shown below.
