A patient goes to the doctor with a cold and sore throat and asks for antibiotics. The doctor refuses to prescribe antibiotics to the patient because the illness is caused by which of the following pathogens?
Fungus
Virus
Protist
Bacteria
The Correct Answer is B
The doctor refuses to prescribe antibiotics to the patient because the illness is caused by a virus. The common cold is a viral infection of the upper respiratory tract ⁴. Antibiotics are not effective against viral infections and are only used to treat bacterial infections.
The other options are not correct because they do not accurately describe the cause of the common cold and sore throat. Fungus, protist, and bacteria are not the pathogens responsible for causing the common cold .

Correct Answer is A
Explanation
The sequence of bases on the complementary strand of DNA would read 5' TCGATCGCA 3'. In DNA, the nitrogenous bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The complementary strand is also antiparallel to the original strand, meaning that it runs in the opposite direction with the 5' end matching up with the 3' end of the original strand. The other options do not accurately represent the complementary sequence of bases or the antiparallel orientation of the strands.
Correct Answer is C
Explanation
