Question

in a class the total number of students who appeared in a exam is 17 the number of students who failed the exam is twice the number of students who passed the exam which equation will help in finding the number of students passed if we assume the number of students appeared to be x​

Answer 1

Answer:

There is an error in your question

Step-by-step explanation:

Total number of students who appeared in the exam = 17

Number of students who passed = x

Number of students who failed = 2x

Therefore, 2x+x=17

3x=17

x=17/3

Which is physically not possible

Answer 2

Answer:

Answer:

Some dinoflagellates possess the remarkable genetic, biochemical, and cellular machinery to produce bioluminescence. Bioluminescent species appear to be ubiquitous in surface waters globally and include numerous cosmopolitan and harmful taxa. Nevertheless, bioluminescence remains an enigmatic topic in biology, particularly with regard to the organisms’ lifestyle. In this paper, we review the literature on the cellular mechanisms, molecular evolution, diversity, and ecology of bioluminescence in dinoflagellates, highlighting significant discoveries of the last quarter of a century. We identify significant gaps in our knowledge and conflicting information and propose some important research questions that need to be addressed to advance this research field.
