Which diagram? There isn’t any there lol

Answer: False
Explanation:
The repression of lac operon is mediated by the catabolite activator protein (CAP). The RNA polymerase can attach to promoter site, only when CAP combined with cAMP is available. Bacteria only accumulate cAMP only when starved. But when glucose is present, cAMP is not available and so CAP-cAMP is not formed. Hence the lac structural genes is turned off in the present of glucose.
Therefore the mechanism by which glucose inhibits the expression of the lac structural genes is by catabolite repression.
Whereas the process by which lactose stimulates the expression of lac operon is by derepression/allosteric regulation. Lactose binds to the lac repressor and deactivate it by causing it to change shape so it doesn't bind to the DNA
Explanation: Outer shell electronic configuration for Group 18 is :
( have 8 electrons in the outer shell)
The electronic configurations for other groups are:
( have 1 electron in the outer shell}
( have 2 electrons in the outer shell)
( have 5 electrons in the outer shell)
( have 6 electrons in the outer shell)
( have 7 electrons in the outer shell)
Comparing the electron configurations of group 18 to other groups.
Group 18 has fully filled outer shell, that is 8 electrons in the outer shell, while others are partially filled.
