Question 6

how many bacteria for each body cell

Answer 6

10

Question 7

why does bacteria have many diff shapes

Answer 7

shapes by synthesis of cell wall

Question 8

what is centre of bacterial chromosome

Answer 8

dna binding protein and rna

Question 9

how many chromosomes does bacteria have

Answer 9

1 chromosome 1 copy for each allele haploid no chromatin naked chromosome

Question 10

what copy does bacteria pass top daughters

Answer 10

same copy

Question 11

what does proteins in bacterium do

Answer 11

they segregate its chromosome

Question 12

gram -ve

Answer 12

layer of peptide very thing

Question 13

gram =ve

Answer 13

very tough very resistant to things like drying out and other insults since peptidoglycan protects them

Question 14

exterior of prok cell is

Answer 14

rigid and multilayered

Question 15

peptidoglycan

Answer 15

cell wall sets of sugar joined together by amino acids

Question 16

cytopplasmic memb has

Answer 16

charged head groups

Question 17

outer memb box sugar

Answer 17

sugars joined on phospholipid head stick out onto the surface

Question 18

yellow box

Answer 18

poly sacharide coating

Question 19

what does the outer strings do

Answer 19

make up capsule of bacterium

Question 20

trans memb protein

Answer 20

same as euk memb

Question 21

cell wall determines

Answer 21

shape

Question 22

what are flagella and pilli used for

Answer 22

motality and attachment

Question 23

does bacteria have rivbosomes

Answer 23

yes

Question 24

what is capsule made of

Answer 24

largely made of sugar lots of sugar outside and then they also secrete its own sugar

Question 25

how does capsule help

Answer 25

prevents it from losing water can protect viruses from killing them like bacteriophages can stop immune cells from recognizing bacterium our immune cell usually recognize protein sitting outside of cell if cell has capsule very hard to recognize they can make bio films which make it even more slimy

Question 26

bacterial virulence
