When glucose is present, enzyme IIAglc is and LacY is . a. phosphorylated; inhibited b. not phosphorylated; inhibited c. phosphorylated; activated d. not phosphorylated; activated

Option B, not phosphorylated; inhibited

Explanation:

Glucose 6 acts as a catobolite repressant . A catobolite repressant which is usually a carbon compound inhibits the operon transcription. In the presence of glucose -6, unphosphorylated enzyme IIAGlc  inhibits the transportation system and hence prevents the utilization of lactose. Glucose‐6‐phosphate and other non‐PTS carbon causes inducer exclusion thereby leading to dephosphorylation of enzyme IIAGl without getting transported.

Hence, option B is correct

the eggs of the insects should be the first thing collected at the scene.

false

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
