Answer that does not describe the structure of an atom: The electron clod is a small and compacted space around the nucleus.
Bye and thx ;)
I think its d the plante kingdom
The right answer is The lac operon would be transcribed constitutively.
An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.
If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.
Polar molecules occur when two atoms do not share electrons equally in a covalent bond. While polar molecules have two parts with opposite charges (i.e., positive and negative), nonpolar molecules have no dipole, meaning that there is molecular symmetry, which results in no opposing charges.
