How do animals use bioluminescence for communication and attracting prey?

On average the resolution a healthy human eye can perceive is between 0,4 and 1 arcminute*. Before we translate this into pixels used by displays in use today, ... The paradigm produced high-resolution eye-tracking data from an experiment on continuous upright and inverted 3∘ sized face detection in both background and no- ... Jul 27, 2015 ... A healthy human eye has three types of cone cells, each of which ... The limits of our visual resolution, or acuity, come into play here. Since one degree contains sixty minutes, a visual angle of one minute of arc is 1/60 of a degree. The spatial resolution limit is derived from the fact that one ... Mar 5, 2021 ...
