Question

bacteria the scientist found that bacteria a has a growth rate of 0.99% per minute, while bacteria b has a growth rate of 0.018% per second. determine which bacterium has a faster growth rate. explain bacteria a has a faster growth rate. bacteria a grows at a rate of 0.99 % per minute. bacteria b grows at a rate of 0.018 % per minute.

Explanation:

Step1: Convert B B's rate to per minute

There are 60 seconds in 1 minute. Multiply Bacteria B's per-second rate by 60:
$\text{Growth rate of B (per minute)} = 0.018\% \times 60 = 1.08\%$

Step2: Compare the two per-minute rates

Bacteria A's rate: $0.99\%$ per minute
Bacteria B's rate: $1.08\%$ per minute
Since $1.08\% > 0.99\%$, Bacteria B is faster.

Answer:

Bacteria B has a faster growth rate. When converting Bacteria B's 0.018% per second growth rate to a per-minute rate ($0.018\% \times 60 = 1.08\%$ per minute), it is greater than Bacteria A's 0.99% per minute growth rate.
