5. 3. which of the tissues you have observed has long narrow lacuna surrounded by long narrow fibers going all in the same direction? when looking at a slide you see what appears to be open spaces with small cells in it, this all is surrounded by layers of connective tissue. what type of tissue is being observed?

The spongy bone tissue is the tissue exhibiting long narrow lacuna enveloped by long narrow fibers all going in the similar orientation. The spongy bone comprises an irregular lattice of thin columns of bone known as trabeculae that contain osteocytes, lamellae, canaliculi, and lacunae. The lacunae are enveloped by long narrow fibers, which go in a similar direction.  

In the second case, the tissue observed in a slide, exhibiting open spaces with small cells, and is enveloped by the layers of connective tissue is hyaline connective tissue.  

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

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.
