Answer:
Basically, most antibiotic drugs are not effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of diameter of the bacterial growth . <u>This is because the diameter is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a measure of how effective it can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control the bacteria, While a large diameter is an indication of low effectiveness of the drug.
Based on this analogy, penicillin with wide usage for control of bacteria growth with diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm or 6mm depending on type of bacterial.
Therefore, the least 3mm diameter presented by penicillin is an indication that , antibiotic drugs are not effective enough, and further research need to be done to control growth of bacteria and therefore its pathogenic effects.

Answer:
Mollusca Phylum
Gastropoda class
Explanation:
The Mollusca Phylum is one of the most noticeable phyla that includes a wide variety of forms.
The ancestral Mollusca used to habit the pre-cambric oceans. It was bilaterally symmetrical, with a well-defined head that had tentacles and ocellus. Its ventral surface was plane and muscular, shaping a reptant foot. The dorsal surface was protected with a convex and oval shell.
The Gastropoda class is the richest class among all mollusks. This class experienced a characteristic torsion in their shell. This twist also involved the visceral mass, the mantle, and the mantle cavity. But by the time that this torsion occurred, the shell had already experienced a turn into a coil shape, which was then followed by its torsion.
The typical gasteropod´s shell is a conical structure composed of several tubular spirals containing the individual´s visceral mass. The biggest spiral ends as an opening from which the head and the food protrude.
Answer:
I would say fossil evidence because fossil and rock clues are what led to Wegener's theory of Continental Drift
Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.
- An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
- The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
- The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
- To aid in preventing fraud, MINs and ESNs can be electronically checked.
