Which one of the following statements is correct regarding sexually transmitted diseases (STDs)?
Correct answer: D. The chances of a 5-year-old boy contracting an STD are very little.
- A. A person may contract syphilis by sharing milk with one already suffering from the disease.
- B. Hemophilia is one of the STDs.
- C. Genital herpes and sickle cell anemia are both STDs.
- D. The chances of a 5-year-old boy contracting an STD are very little.
Explanation
STDs are primarily transmitted through sexual contact, so the likelihood of a 5-year-old boy contracting an STD is very low due to the absence of sexual activity at that age. Option A is incorrect because syphilis cannot be contracted through sharing milk. Option B is incorrect because hemophilia is a genetic disorder, not an STD. Option C is incorrect because, while genital herpes is an STD, sickle cell anemia is a genetic disorder.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
