<h2>d) option is correct </h2>

Explanation:

The stringent response occurs in response to low energy store

For example when there is low level of lactose it means energy level is low so there will be no transcription of genes and hence transportation and catabolism of lactose will be inhibited

When E coli is grown in mixture of both glucose and lactose, at high glucose concentration the growth rate is maximum and lactose catabolism is repressed, this called as catabolite repression and it is due to level of cAMP

puteri [66]

Answer:

jayfeather friend me

Explanation:

Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
