Answer:
a. synergism
Explanation:
When two different drugs inhibit a single biochemical pathway of microbes less quantity of each drug is required in combination to produce the effect than when used separately. This effect is called synergistic interaction of drugs.
Both beta-lactam antibiotics such as penicillin and cephalosporin and clavulanic acid serve as beta-lactamase inhibitors and inhibit the beta-lactamase-producing bacteria. Therefore, beta-lactam antibiotics and clavulanic acid are used in combination to control these enteric bacteria.
Answer: C) Apical
Explanation: An epithelium has a free surface, the apical surface, exposed to the outside, and an attached surface, the basal surface, resting on the underlying connective tissue.
Answer:
Protein production in prokaryotes begins even before the completion of transcription. This means that ribosomes attach to the mRNA being generated even before transcription process is terminated. Therefore translation occurs in concurrence with transcription. This is because there is no definitive boundary between the nucleoid and cytoplasm.
In eukaryotic cells, the nucleus is separated from the cytoplasm by the nuclear membrane. This means transcription has to complete before the translation of proteins occurs. This is because the ribosomes are located in the cytoplasm while the DNA is in the nucleus.
This difference is part of the reason prokaryotic cells are able to respond really fast to an environmental stimuli as compared to eukaryotes. Remember in addition mRNA in prokaryotes do not need splicing (as required in eukaryotes) adding to quick protein production.

A scientific question is one which can be tested using a set of experiments and comparing with a control variable. Out of the given questions, the nonscientific questions are:
"Why do people in my neighborhood have more cats than dogs?"
"How can the position of the stars and planets be used to predict the future?"
Both of these questions can not be answered through the scientific method, so they are nonscientific.
