Since that time, microscopes have undergone many changes and improvements. Today s electron microscopes are far more powerful than anything Leeuwenhoek could have imagined they objects to appear (X) magnify objects to make them appear 200,000 times larger than their actual size. Some can even enable If it had not been for allow scientists to see individual atoms. Without the development of the microscope, many important,.

The study showed that office workers who habitually stopped what they were doing to respond to s and texts were in a similar mental state to someone who had not slept the night before. Of the 1,100 study subjects, over half said they immediately responded to all s, and the study confirmed that this kind of continual disruption in the workplace can Glenn Wilson , 100,,. drastically affect employees. The researchers even reported that workers were shown to suffer a temporary IQ drop of roughly 10 points when they were repeatedly interrupted by phone calls and s. There is no question that, when used appropriately, communication devices and services can boost productivity. However, when their use is not controlled, they may compromise workers mental states and therefore 10 IQ.,.,. also their performance. Technology can decrease productivity in the office by disturbing workers concentration

5 TEST Scientists recently discovered that while real Arctic reindeer don t have glowing red noses like the fictional Rudolph, they can change their eye color. Reindeer experience weeks of total darkness in in order that winter in the Arctic tundra where they live. In order to survive, they need to adjust their eye color to dark blue from yellow. Blue eyes are beneficial to Blue eyes reindeer in the winter because they can capture,..,.. more light than yellow eyes. The reflected light disperses more throughout the ~ eye once it changes from yellow to blue, and this allows the light to reach more photoreceptors. The reindeer are then able to see more of their surroundings, although what they see is not very clear. However, they see well enough to be able to,.,.,. spot and avoid predators
