She is respected.
Literal
She [topic-は] is-being-respected.
尊敬されている is the resultative passive of 尊敬する ('to respect [a person]') — passive marking that she is the recipient of the respect, ~ている marking the ongoing state. With agent unmentioned (no ~に or ~から), the passive reads as 'in general / by people / by everyone.' This 'general agentless passive' is common when the speaker wants to describe a state of being respected without singling out any particular admirer.
