Animals sleep patterns

 Mammals sleep to preserve their energy and recover physical and mental energy. The amount of sleep a mammal needs hinges on many factors, including environment, body size, diet, age, and the safety of its sleep place. Whether animals settle on land or sea can also influence how much sleep it requires. Different mammals spend various amounts of time in non-REM sleep and REM sleep. However, all mammals examined exhibit signs of REM sleep, suggesting that mammals dream as humans do. Talking about mammalian sleep is often classified as monophasic or polyphasic. Monophasic sleep represents animals who get their sleep in one concentrated period. For instance, humans are monophasic sleepers. Our circadian rhythms stimulate us to sleep for prolonged periods at night and be active and alert during the daytime. Polyphasic sleepers have a rest for multiple periods throughout a 24-hour cycle. Polyphasic sleep is familiar, as many animals must keep caution against predators. However, if dangers ar

The Periodic Table of Endangered Elements

The European Chemical Society has released a revised version of the Periodic Table. In this Periodic Table, the area of each element links to its number of atoms on a logarithmic scale. Based on current consumption levels, the color coding reveals whether there is enough of each chemical element or whether the element is becoming deficient. While these elements don't technically run out but transform, some are being used up extremely quickly, where they may rapidly become exceptionally scarce. One chemical element worth pointing out in the Periodic Table is carbon, which is three different colors: green, red, and dark gray. Green , because carbon is in abundance as carbon dioxide Red , because it will in the nearest future cause several considerable problems if consumption habits don't change Gray because carbon-based fuels often come from conflict nations. The carbon cycle balances photosynthesis, by which plants grow, taking up carbon dioxide, with respiration, by which we
