An early life stage (ELS) test is a chronic toxicity test using sensitive early life stages like embryos or larvae to predict the effects of toxicants on organisms. [1] ELS tests were developed to be quicker and more cost-efficient than full life-cycle tests, taking on average 1–5 months to complete compared to 6–12 months for a life-cycle test.
Some high schools, to reflect the varying skill required for different course levels, will give higher numerical grades for difficult courses, often referred to as a weighted GPA. For example, two common conversion systems used in honors and Advanced Placement courses are: A = 5 or 4.5; B = 4 or 3.5 [5] C = 3 or 2.5; D = 2 or 1.5; F = 0 [19]
Grading in education is the application of standardized measurements to evaluate different levels of student achievement in a course. Grades can be expressed as letters (usually A to F), as a range (for example, 1 to 6), percentages, or as numbers out of a possible total (often out of 100).
Generally, universities require that students have taken a university-prep grade 12 English course. Additionally, programs involving mathematics and/or natural science often require students to take a university-prep grade 12 calculus course, as well as university-prep grade 12 biology, chemistry, and physics. Overall, universities base ...

Life cycle energy analysis (LCEA) is an approach in which all energy inputs to a product are accounted for, not only direct energy inputs during manufacture, but also all energy inputs needed to produce components, materials and services needed for the manufacturing process. [111] With LCEA, the total life cycle energy input is established. [112]
