The Sonoran Desert is home to many species that form close
relationships called.
For example, the Phainopepla (a bird)
and Mistletoe (a plant) have a close relationship where the bird eats the
plant's berries and spreads the seeds with its droppings. This is called
because the bird receives nutrition and the plant is able to
reproduce. Mistletoe forms another type of relationship between other
plants, such as the Desert Ironwood. When its seed germinates, the
Mistletoe digs its roots into the connective tissue of another tree and
takes away its water resources. This is
where the Mistletoe
acts as the
and the Desert Ironwood acts as the
While the Mistletoe makes its home in Ironwoods, the Cactus Wren
makes its nests by burrowing holes in Cholla Cacti. This is an example of
because the cactus is still alive and relatively unaffected, but
the bird is provided safety and shelter.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

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.
