The skin turns brown or black faster in the refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.
A refrigerator, a counter, and two bananas (preferably from the same cluster).
two bananas, a counter, a fridge, and some time.
It does not matter what brand. Bananas turn brown faster in the refrigerator.
it turns brown in the refrigarator
The banana in the refrigerator browned faster than the banana on the counter. The cold temperature makes a banana's skin brown faster. The banana in the refrigerator is still firm though, where as the banana on the counter is softer.

If you mean a cut open fruit, no. Both are slowed with application of lemon juice.
Take two bananas on the same stem, separate them and place one in the refrigerator and the other on the counter to see which will brown faster.
Cold causes the warm climate fruits cells to break down faster.

In the science project determining if a banana browns faster in the refrigerator or on the counter, the independent variable is the location where the banana is stored (refrigerator vs. counter). The dependent variable is the rate of browning of the banana, which can be measured by factors such as time taken to brown or the extent of browning observed.
