A consumer group is interested in the effects of the speed and the weight of a truck on a truck's gas mileage. A truck's gas mileage is the number of miles it can travel for each gallon of gas it uses. First the group decides to test if a truk's speed affects its gas mileage. They take two identical trucks and drive one at 30 miles/hour and the other one at 45 miles/hour on the same road. They make sure that the two trucks have the same weight. Why is it important that the two trucks have the same weight? A. By using trucks of the same weight, the group can learn about both the effect of the weight and the effect of the speed on the gas mileage.

B. By using trucks of the same weight, the group can learn about the effect of the weight on the gas mileage

C. If the trucks do not have the same weight, the group cannot learn about the effect of the speed on the gas mileage.

D. It is NOT important for both trucks to have the same weight because the group is not testing the effect of the weight on the gas mileage.​

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

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.
