<p>[Although] she considers her chemistry research [complete], she [has heeded] her professors advice and [is conducting] three additional experiments. [No error]

<p>“Has heeded” refers to an action done in the past.</p>
<p>“Has been heeding” refers to an action done in the past BUT still continuing into the present. </p>
