answ er s + r ationales (Gr adedA+)
7 Common properties and processes of living organisms - answer Order,
Reproduction, Growth and development, Energy processing, Response to
environment, Regulation, Evolutionary adaptation
Biological Organization Hierarchy (smallest to largest) - answer Molecule,
organelle, Cell, Tissues, Organ, Organ system, Organism, Population, Community,
Ecosystem, Biosphere
Prokaryotic Cell - answer lacks a nucleus with free floating DNA, came first,
roughly 4.3 bya
Eukaryotic Cell - answer has a membrane bound nucleus, has a number of
membrane bound organelles roughly 2.1 bya
DNA - answer The genetic material of all cells. Nucleic acid that contains genetic
instructions for development and function of all known organisms. Diversity of life
is because of DNA
Evolution - answer change in heritable characteristics. Responsible for unity and
diversity of life
3 Domains of Life - answer Bacteria-most diverse and widespread prokaryotes
, Archaea- Prokaryotes that often live in earths extreme environments
Eukarya- Have eukaryotic cells. Single celled and multicellular protists. (plants and
animals)
Charles Darwins 2 main points on Evolution - answer 1. Species are descendants
of ancestral species
2. Mechanism for evolution is natural selection
6 steps to scientific method - answer 1. Form a question
2. Research
3. Hypothesis
4. Experiment
5. Analyze data/conclusion
6. Report
Natural Selection - answer Process where organisms better adapted to their
environment tend to survive and produce more offspring.
Editing process, not creative.
Individuals do not evolve, populations do. It is not goal directed and does not lead
to perfection
Artificial Selection - answer Selective breeding of domesticated plants or animals.
Humans select individuals with desired traits.
