Draw the exponential growth and logistical growth curves on the board. Which is more realistic to actual populations?
Logistical curve

Explain relative abundance vs species richness
Species richness is the amount of different species present in an area Relative abundance is the proportion that each species represents in the community. Amount of each species. Page 851-852

Compare Covalent bonds with Ionic bonds.
Covalent bonds are when two atoms SHARE electrons by bonding together. Ionic bonds are when one atom gives one or more electrons to another to fill a valence shell and bond together

Explain Phagocytosis
Phagocytosis is when a cell engulfs a particle which has entered the cell, into a food vacuole which fuses with a lysosome and eliminates/eats the particle.

What do flagella and cilia do?
Help propel/move the cell
200
Explain the fundamental niche vs the realized niche
Fundamental is the entire area that the organism COULD inhabit. Realized is the area that they DO inhabit.

Define and compare integral proteins and peripheral proteins in a cells membrane.
Integral proteins go all the way through the membrane Peripheral proteins are not embedded in the membrane and are only on one side of it- do not go thru.

Explain osmosis
Osmosis is the passive diffusion of water across selectively permeable membranes. The goal is to create equilibrium across the membrane in regards to other solutes. Page 100

What are some components of a cell's cytoskeleton?
Microtubules, centrosomes and centrioles, cilia and flagella, filaments

Give all the information you know about hydrogen bonds
Strong and weak due to partial positive charges in hydrogen, in DNA, Chapter 2.

Define batesian mimicry and contrast it with mullerian mimicry. Additionally, contrast aposematic coloration with cryptic coloration.
Batesian mimicry: a harmless species mimics a harmful one to scare away predators Mullerian: Two unfavorable species mimic eachother-bees and hornets Aposematic Coloration: bright, warning colors Cryptic Coloration: camouflage

If an animal cell is placed into a Hypertonic solution, which way will water move? Draw it on the board.
Water moves to hypertonic
300
Place these in order: Secondary consumer, primary producer, primary consumer, tertiary consumer, quaternary consumer. Give an example of each
Primary producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer Dandelion, insect, field mouse, snake, hawk

What are the differences between prokaryotic and eukaryotic cells?
Euk: has nucleus, divides by mitosis, large, Prok: Nucleoid- not a true nucleus, divides by binary fission
300
What do ribosomes do?
Make proteins in cytosol or rough ER
400
Define the endosymbiont theory (do not confuse with endomembrane system)
An early ancestor of eukaryotic cells engulfed prokaryotic cells, which later became mitochondria and chloroplasts. There is evidence for this because of the fact that mitochondria and chloroplasts have their own DNA and are similar to each other- double membrane, ribosomes, independent of the larger cell which they inhabit
400
Compare hydrophobic to hydrophilic.
Things that are hydrophobic do not like water and will not associate with it, things that are hydrophilic do like water and will associate with it.
400
Define a dehydration reaction and a hydrolysis reaction
Dehydration reactions are when two molecules are bonded together, and a water molecule is lost in the process. Hydrolysis reactions are the opposite, when a molecule breaks apart into two or more molecules, and a water molecule is gained. Page 45

What is the efficiency of energy when moving up a trophic structure?
10%. Page 872.
400
What are the levels of a protein structure? Explain them
Primary structure- chain of amino acids, secondary- starts to twist up, tertiary- 3d shape created, quaternary-more than one 3d structures joined together
500
Something with a low numbered pH is what? Something with a high numbered pH is what?
Acidic, Basic

Explain the importance of the water cycle
Water is essential to all living beings and influences the rates at which ecosystem processes occur.

What is facilitated diffusion?
Transport proteins aid in the movement of materials across a cell membrane. There are channel proteins and carrier proteins.
