Question 2

surfers in the eukaryotes are hydrophobic or hydrophilic

Answer 2

they are hydrophilic

Question 3

these structures hydrolyze enzymes

Answer 3

lysosomes

Question 4

this structure permits the translation of proteins destined for secretion directly into its lumen

Answer 4

Rough Er

Question 5

this structure does lipid synthesis and detoxification; transports proteins from the RER to the Golgi apparatus

Answer 5

smooth ER

Question 6

this is a membrane bound sac that’s good for exocytosis

Answer 6

Golgi apparatus

Question 7

these break down very long chains of fatty acids with β-oxidation

Answer 7

peroxisomes

Question 8

actin and myosin are examples of

Answer 8

microfilaments

Question 9

structure of centriole

Answer 9

9 triplets of microtubules

Question 10

pseudostratified epithelia

Answer 10

appears to have multiple layers, but is just one layer

Question 11

spherical shaped bacteria is

Answer 11

cocci

Question 12

rod shaped bacteria is

Answer 12

bacilli

Question 13

gram + cells walls have a thick layer of —

Answer 13

peptidoglycan

Question 14

chemotaxis

Answer 14

ability to move toward or away from stimuli

Question 15

a subset of plasmid

Answer 15

episome

Question 16

the only genetic recombination process that requires a vector

Answer 16

transduction

Question 17

genetic elements that are capable of inserting and removing themselves from the genome

Answer 17

transposons

Question 18

the protein coat of a virus

Answer 18

capsid

Question 19

positive vs negative sense viruses

Answer 19

in positive sense, the genome may be directly translated to functional proteins by ribosomes of the host cell and in negative sense, it requires synthesis of an RNA strand complementary to the negative-sense RNA strand which can then be used as a template for protein synthesis
