Eukaryotes and Prokaryotes
100
Ability to observe two adjacent objects as distinct from one another.
What is resolution?
100

Laboratory alteration of genetic material to a different species.

What is Horizontal Genetic Engineering?

100
This pH is considered to be neutral.
What is pH 7?
100
Write out escherichia coli in proper binomial nomenclature.
E. coli All italicized.
100
Have a nucleus.
What are Eukaryotes?
200
The most commonly used type of microscopy. Has a range from the biggest of cells to the smaller bacteria.
What is Light Microscopy?
200
Complete genetic makeup of the organism.
What is the genome?
200
What type of bond holds the hydrogens to the oxygen in water?
What is a polar covalent bond?
200

Extracellular organelle used for locomotion?

What is the flagella?

200

Plants fit into this category of cell types.

What are Eukaryotes?

300
The relative differences in the lightness, darkness, or color between adjacent regions in a sample (can be enhanced by dyes).
What is contrast?
300
A hypothesis that has been tested many times, has a large body of evidence to support it, and can make many predictions.
What is a theory?
300
Name one of the important interactions/bonds that hold a protein together in it's secondary/tertiary structure.
Hydrogen bonds Ionic bonds Hydrophobic effect Disulfide bridges Van der Waals interactions
300
Removes a water to join 2 molecules.
What is a dehydration reaction?
300
Region where DNA is concentrated in a prokaryote.
What is a nucleoid?
400
The ratio between the size of an image produced by a microscope and the images actual size.
What is magnification?
400

Regions of proteins that perform a particular job.

What is a domain or binding site?

400
How many electrons do H, C, O, and N have in their outer shell? How many electrons do those same atoms need to fill their outer shell (how many bonds do they want to make)?
H: 1, 1 C: 4, 4 O: 6, 2 N: 5, 3
400
Organelles that breakdown macromolecules in the cell. (Recycling Bin of the cell).
What is the lysosome?
400
Are prokaryotes generally multicellular?
No
500
This type of microscope uses electrons to scan the surface of a specimen.
What is a Scanning Electron Microscope?
500

Functions in bacteria to trap water, give protection, and help evade the host organisms immune system.

What is a glycocalyx or cell wall?

500
What two regions are found on a phospholipid, and what does this cause them to do in an aqueous environment?
They have a polar head and a nonpolar tail. This allows them to create a lipid bilayer in the water (where the hydrophilic head is facing the water, and the hydrophobic tails are hidden inside).
500
Give the letters of bases in DNA and RNA. Are they purines or pyrimidines?
DNA: Purines: A, G Pyrimidines: T, C RNA: Purines: A, G Pyrimidines: U, C
500
A new organism is discovered. It has many mitochondria. Prokaryote or Eukaryote?
Eukaryote.
