Scientists studying climate change have found that the effect of global warming is not only a higher planetary temperature, but also a universal change in seasons, specifically earlier springs and later autumns. Though some argue that this is an advantage because it presents a longer summer growing season, others fear that too many animal species will be unable to adapt and will become extinct. Which of the following is the best piece of evidence to support the conclusion that a longer growing season will hasten the extinction of some animal species?A. Squirrel and chipmunk species are unable either to consume or to store all the nuts and berries produced during a longer growing season. B. Fungus species typically produce spores only once a year and are unable to produce enough spores to release spores again before the end of a longer growing season. C. Butterfly species that respond quickly to changes in temperature hatch caterpillars and undergo metamorphosis into butterflies earlier, flying away before bird species that feed exclusively on them have hatched their young. D. Salmon species that rely on changes in temperature to signal the start of annual migrations leave their freshwater birthplaces earlier, before they have fed sufficiently on freshwater insects to reduce their number.\E. Reptile species that hibernate during winter months must emerge from hibernation sooner and spend a longer time searching for food before mating in mid-summer.

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.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
