Answer:
Yes, if there is a mutation in the operator of the lac operon in a cell such that the lac repressor always stays bound to the operator. If lactose is added to the cell, the lac repressor loses its ability to bind DNA. It clear off the operator, clearing the way for RNA polymerase to transcribe the operon.
A) Receiving is to sending
There often many dendrites per neuron, but only one axon. dendrites branch in many directions and are sensitive to signals from other neurons. They receive these signals and pass them to the soma (the part of the neuron that contains the nucleus). It is the axon that sends these signals to other neurons.

Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
