Why does a banana skin turn black after a few days, even when the banana is kept in the refrigerator


Why does a banana skin turn black after a few days, even when the banana is kept in the refrigerator?

Its nice question people used face from thier Childrens, Most of us really dont know how its happened even we kept in Refrigerator.. Here is the exact answer for that to help to save your face.

The green skin of banana contains a gaseous plant hormone, ethylene, which diffuses into the fruit and hastens the process of ripening. It is yellow when the fruit is ripe and turns black with the production of more and more ethylene. The large number of enzymes of Kreb’s cycle convert citric acid, mallic acid and oxalic acid into glucose in a banana, to make it sweet during the process of ripening. When the banana is kept in the refrigerator, the enzymatic reactions are stopped by the cold but the production of ethylene hormone continues.
This turns its skin black.


What is a DNA signature?

Every human cell contains DNA (DeoxyriboNucleic Acid), the blue print for all life and a genetic code that is unique to each individual. DNA is nature’s digital signature. Our DNA signature helps forensic experts in detecting crime, tracing family lineage, etc. Various agencies are working on creating DNA signatures’ data for future use.

What are the emerging technologies for information backup and archiving?

What are the emerging technologies for information backup and archiving?

We are seeing LTO (linear-tape open) for high-end enterprises, with drives capacity up to 14.8 terabytes, gaining momentum. Small area networks are going for VXA, which is replacing DDS technology. VXA tape drives performs better than DDS with higher capacity. As a alternative tape backup technology, VXA is data reliable, costeffective and offers inexpensive migration from DDS.
As a result of constant innovations, tape has been extraordinarily resilient in surviving challenges and remains the value-oriented IT managers’ first choice for data backup. Analysts are predicting significant growth in the number of tape storage units shipped in the next five years, including double-digit growth in tape automation products purchased.

When behemoths like HP and IBM are pushing the concept of one-stopshop IT solutions, including storage, what position is a specialised and niche company like Exabyte taking? The strategy is to get IBM and HP to sell our products. IBM is selling our VXA range of solutions for its X and P range of servers. For market penetration, we go aggressively after the value-added resellers (VAR) channel. How is the concept of disaster recovery (DR)/business continuity planning (BCP) taking shape globally?

There is tremendous desire among the enterprises for backup. Data reliability and data integrity are very important.
