if you discovered a single-celled, prokaryotic organism living in the waters of a hot spring, then in which of the 3 domains of life would this organism probably be classified?

Back 20

domain archaea

Front 21

which are generally more complex: eukaryotic cells or prokaryotic cells?

Back 21

eukaryotic

Front 22

bacteria are said to be upiquitous. what does that eman?

Back 22

they are found almost everywhere

Front 23

bacteria can be classified as aerobic, anaerobic, or facultative, based on their ocygen needs. bacteria that can make teir ATP through aerobic resiration pathways would belong to which category or categories?

Back 23

aerobic and facultative

Front 24

bacteria can be classified as autotrophs or heterotrophs, based on how they obtain the carbon atoms they need for producing organic molecules. Bacteria that get their carbon atoms by breaking down the nutrients in your blood cells would belong to which category?

Back 24

heterotroph

hemoglobin

Front 29

hemoglobin A contains how many polypeptide chains?

Back 29

4

Front 30

hemoglobin A and hemoglobin S differ in which of the polypeptide chains

Back 30

the beta chain

Front 32

what is the anatomical difference between a red blood cell that has hemoglobin S molecules versus one that has hemoglobin A molecules?

Back 32

hemoglobinS molecules cause the red blood cell to have a sickle, or crescent, shape.
