Not all types of memory cards will feature these; SD and Memory Sticks often include the write protect switch.

If the write protect switch is in the locked position, then it will not be possible to write to the card. It will, however, be possible to read the photographs from the card if they are already there. Mini and Micro SD cards do not feature a switch, however, when they are placed in the SD card adaptor to fit into your computer, there is a lock switch. Some people mistakenly believe that this is to lock the card in position, however, this is actually a write protect switch.

Does looking at this image of a person yawning make you yawn? About half of adults yawn after someone else yawns due to a universal phenomenon called Бcontagious yawning. Б Contrary to popular belief, a new study from Duke University suggests that contagious yawning isбnotбstrongly related to variables like empathy, tiredness, or energy levels. Previous studies have suggested that there is a connection between contagious yawning and empathy. However, researchers at The Duke Center for Human Genome Variation found that contagious yawning may decrease as people age and may not be associated with empathy. Theб, titled БIndividual Variation in Contagious Yawning Susceptibility Is Highly Stable and LargelyбUnexplained by Empathy or Other Known Factors,Б was published March 14 in the journalб

There are many causes of this behavior but the main reason behind any type of digging behavior goes back to their instincts.

 why does hydrogen bonding help ice cubes float

why does hydrogen bonding help ice cubes float

The simple answer is that ice is less dense than water. The question then becomes: Why is ice, which is water in solid form, lighter than water in its liquid form? Something must be happening to water when it freezes. One molecule of water has two hydrogen atoms and one oxygen atom, or H2O. The hydrogen atom is slightly positive, and the oxygen atom is slightly negative. At room temperature, these water molecules are loosely linked and free to move around easily, which is what defines the liquid state of matter. Once the temperature hits 32 F, or 0 C, the molecules line up in a rigid six-sided honeycomb structure, with water moleculesБthe more positively charged hydrogen attracting the more positively charged hydrogenБlinking up with each other in a process called hydrogen bonding. This
