Which statement about platelets is false? platelets have nuclei. platelets are cell fragments. platelets are involved in blood clotting. platelets differentiate from the daughter cell of a stem cell. none of the above statements are false.

Platelets have nuclei

would be the correct answer. While reading all the statements i recognized all of them as traits of platelets except the obvious one which is Platelets have nuclei. platelets have no nuclei.

Platelets have nuclei.

Explanation:

Platelets are also called as thrombocytes. These are irregularly shaped structures which do not posses nucleus. They are not considered as true cells instead they are called as fragments. As they do not posses nucleus, they do not contain the nuclear DNA. But they do contain mitochondria, hence they also produce mitochondrial DNA. Their main function is to produce blood clots at the site of injuries. Hence, they prevent the loss of excess blood during bleeding.

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.
