Bequerel left his crystals in the sunlight for several hours as part of his experiment.
Becquerel left his crystals in the sunlight to study the phenomenon of fluorescence. He discovered that the uranium crystals emitted radiation that fogged photographic plates, leading to the discovery of radioactivity.
Quartz crystals can be energized by placing them in direct sunlight or moonlight for a few hours, burying them in soil for a day, or using visualization and intention to cleanse and charge them with positive energy. You can also place the quartz near a cluster of clear quartz crystals to absorb their energy.
If you think to potassium "permanganate" this compound can be decomposed under the influence of UV radiations.

Dracaena plants thrive in bright, indirect sunlight. They do not require direct sunlight but need a good amount of light to grow well. Place them near a window where they can receive filtered sunlight for several hours each day.

Chickadees are diurnal birds, which means they are active during the day and require sunlight to forage, find food, and navigate their surroundings. They generally need several hours of sunlight each day to maintain their energy levels and carry out their daily activities.
24 hours just like everywhere else. If you mean how much daylight does Anchorage get each day, it varies depending on the time of year. If you were to visit in the summer at the height of the tourist season, say July 4th, you would experience 24 hours of light. Several hours of this time would be much like twilight, not intense sunlight but easily light enough to see very well. The actual sunlight would be around 20 hours or so.
about 14 hours
