8. explain more fully the two extreme degrees of metamorphism.

Two extreme degrees of Metamorphism:

The lower limit temperature of metamorphism is 100-200 degree Celsius. It does not include the physical or chemical formation of sedimentary rocks.The extreme higher limit temperature is 700-900 degree Celsius depending on the pressure and composition of rocks. The ultrahigh metamorphic temperature is 900-1100 degree Celcius. The pressure of the metamorphic process is 100-300 mega pascals.

Progressive Metamorphism is the process which leads the organism to progress towards the evolutionary process where the later stages have more evolutionary progress than the previous stages. Whereas the retrograde Metamorphism is just the reverse of the progressive Metamorphism, where the later stages have less evolutionary progress than the former ones. Tadpole developing into frog is an example of progressive Metamorphism whereas the herdmania larva undergoes retrograde Metamorphism.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
