7 Characteristics of Life - Answer 1. Cells are the simplest units of life; 2. Living
organisms use energy; 3. Living organisms interact with their environment; 4. Living
organisms maintain homeostasis; 5. Living organisms grow and develop; 6. The genetic
material provides a blueprint for reproduction; 7. Populations of organisms evolve from
one generation to the next
Principles of Biology (8-12) - Answer 8. All species are related by evolutionary history; 9.
Structure determines function
10. Complex interactions give rise to new properties of life
11. Biology is an experimental science
12. Biology impacts our society
Scientific Method - Solution 1. Observations
2. Hypothesis
3. Experimentation
4. Data
5. Conclusion
Hypothesis - Solution Proposed explanation based on past observation (trees losing
their leaves).
Theory - Solution Broad explanation of some facet of the natural world from a large body
of evidence. It allows predictions but can never be proven true
Cystic Fibrosis - Answer Mucus in the lungs.
Discovery based sciences used to find CF gene. This lead to experiments to test the
,hypothesis
Natural Selection - Answer Amplifies variations that arise randomly
Descent with modification: Evolution based on. - Answer variation within a given species
and natural selection
Modern synthesis of evolution - Answer Natural variation exists that is caused by
random changes in the genetic material.
If genetic change/mutation promotes individual survival, then the trait may become
more prevalent in future generations through natural selection.
Phenotype - Answer The features evident in an organism are because of gene
expression.
5 areas of evidence which support evolution - Answer -Studies of natural selection
-Fossil Record
-Biogeography
-Convergent evolution
-Selective Breeding
Biogeography-Answer Unique species exist on islands and other remote regions
because the species located there have evolved in isolation from the rest of the world.
Atoms are composed of -Answer Neutrons, protons, electrons
Atomic Number-Answer Equal to the number of protons in an atom of that element
Periodic Table is Arranged by - Answer Atomic number
, Periodic Table: rows-Answer electron shells
Periodic table: columns - Answer from left to right, give the number of electrons in the
outer shell
Elements that constitute a very high percentage of all living substances - Answer C N O
and H
covalent bonds -Answer atoms share a pair of electrons. occurs between atoms whose
outer electron shells are not full
What type of chemical bond is the most robust? -Answer covalent bond
Polar covalent bonds - Distribution of electrons around the atoms creates a difference in
electric charge
Example of a polar covalent bond - Water
Hydrogen Bonds - Very important for life. They are weak polar covalent bonds that
include a bond between H on a polar molecule and the electronegative part of another
Ionic Bonds - One atom is much more electronegative than the other ("steals" electron)
Ion- An atom or molecule that has gained or lost one or more electrons
Solvent- A liquid
Solutes- Substances dissolved in solvent
