BIOL 1010U Lecture 2: Bio Lecture 2
Document Summary
Biol1010: intro to cells - sep 13, 2017. The ability to design or choose traits for babies. How a single cell develops into an organism. How plants convert sunlight to chemical energy. Can be used to produce energy for humans to use (solar panels) Pollinators (like bees and butterflies) are disappearing. How life"s diversity evolved from early microbes. Evolutionary theory doesn"t explain how life began on earth, it only explains what happened once it was already here. Diversity / unity of life explained by evolution: Modern biology uses charles darwin"s theory of evolution through natural selection (1859) as a unifying framework. All organisms are capable of reproduction involving duplication of genetic material with potential for errors to occur. Leads to differences among organisms that enable them___ Have a genome composed of rna and dna (for replication) Have rna and dna from the same nucleotides. Have ribosomes acting as sites of protein synthesis. Undergo rapid metabolic reactions catalyzed by proteins.
