Which phrase accurately characterizes sexually transmitted infections (STIs)? are caused by bacteria, viruses, or parasites
always cause visible symptoms
are rarely transmitted by sexual contact
can be contracted only by women

the first one

Explanation:

i I think it's the first one because viruses usually are the cause of the infections along with bacteria and parasites and they are not always visible and are not rarely by sexual contact but instead mostly, that's why they're called sexual transmitted diseases and cannot only be contacted by women so I think that's the best answer. I'm open to correction

answer; /// the correct answer to the above question is a hospital is responsible for all area (250 feet) around the main building and around areas where inpatient services are provided

so we know the answer cannot be c because no insect or animal starts as an adult

the answer is a. a swimming larvae

because since they are sea animals they automatticaly have to know how to swim they cannot just sink to the bottom

sorry if this is the incorrect answer.
