Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from stimulus of light. This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis.

How long do results take? Rapid HIV tests can give results in 15â60 minutes, or on the same day. âRapidâ refers for the time taken for the results and not the time since exposure that a test can be used. If samples are being sent to another lab, results can take a few days or a few weeks. Rapid blood tests put a pin-prick of blood on a testing strip. This test takes about 15-20 minutes so you can get the results whilst you wait. Some rapid tests also work on oral samples rather than blood.
