The bacteria mutate in response to the antibiotic exposure. Through mutation, some individuals develop the ability to survive at higher antibiotic concentrations. These individuals reproduce while the other bacteria die. Because their
offspring inherit the ability to survive at higher antibiotic concentrations, the
entire population evolves to be more tolerant of antibiotics.

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
