Diversity/Unity of Life
How can we measure relatedness?
Using genes/genetic material to compare organisms
Why is the cell the lowest hierarchy of biological organization?
because it can perform all activities required for life
Name 4/7 properties of life
Order, Energy use, homeostasis, response to environment, reproduction, evolution to adoption, growth
Name a difference between prokaryotic and eukaryotic cells
Prokaryotes: smaller, non membrane bound nucleus/organelles
Eukaryotes: bigger, membrane bound nucleus/organelles
What information is used to produce a phylogenetic tree?
rRNA(ribosomal) genes
Explain how Cells = structural unit of life
All organisms are composed of cells
Atoms are composed of what and what are they charges
protons +
electrons -
neutrons 0
Name the three branches on the tree of life
bacteria, archaea, eukaryotes
Explain how Cells = functional unit of life
cells are the smallest entity that have all the properties of life. each cell can generate an entire organism
draw the anatomy of a cell
nucleus = protons/neutrons
orbital shells= electrons
What is it called when species change over time and are related to each other?
evolution
Explain how cells are fundamentally similar
similar structure/organization
similar metallic strategies
similar hereditary info
(cell FUNCTIONS can vary however)
Name the four types of chemical bonds
Covalent, ionic, hydrogen, van der waals forces
Regarding evolution, what explains why it occurs?
natural selection
Explain how Cells come from preexisting cells
via cell growth and division
life does not arise from non life
What is cohesion
attraction between water molecules due to strong hydrogen bonding
