During biology lab, stacey needs to pour 100 ml of a substance into a beaker. she inspects the beaker before she uses it and sees that there is a small crack in the bottom of the beaker. in order to practice proper laboratory safety, stacey should a. inform her teacher and use a different beaker. b. fill the beaker with water and only use the beaker if it doesn't leak. c. put tape over the crack but go ahead and use the beaker. d. switch beakers with another student in the lab.

The most appropriate answer option is A. inform her teacher and use a different beaker

Explanation:

According to the safety standards specified to perform experiments in a laboratory, Stacey should inform her teacher and try to use a different beaker if she sees a crack on hers.

This is to ensure maximum safety which in no case should be compromised. Because the beaker still might break in the middle of an experiment, even if it was not leaking before or she covered it with a tape, thus causing harm to her.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

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.
