Phantasy [73]3 years ago

Answer:  The correct answer is :  Living systems depend on the polarity of water, because since water is polar it has an unevenly distributed charge, this means that water molecules are slightly positive and negative, for this reason water is a good solvent, this characteristic is essential in organisms. For example, sugars and other nutrients are dissolved so that the blood cells can carry it to cells in the body. If sugars weren't dissolved, they couldn't reach cells. Water also attracts or is attracted to other molecules and polar ions, including many biomolecules, such as sugars, nucleic acids and some amino acids.

xxTIMURxx [149]

Answer:

Letter C is the correct answer.

Explanation:

No Child Left Behind (or NCLB) was a law for K-12 Education in the U.S. between 2002 and 2015 (it was replaced by Every Student Succeeds Act that year) and the main issue was how children were learning at school.

Options A, B, and D are related to the academic status of the professor, since A talks about tests taken by teachers; letter B refers to state qualifications in the area teachers have in charge; letter D also talks about how professors can prove they are able to teach their subjects: all these options are strictly related to how children can learn and how exams and certifications can help teachers in this task. On the other hand, Letter C does not relate directly to students' performance in the classroom, and that is why this is the correct answer.

Do we need it now electoral college
ki77a [65]
Yes. Without the Electoral College, it would diminish the influence of smaller states and rural areas of the country; lead to more recounts, contentious fights over provisional ballots, and conflicts over the results of presidential elections; and encourage voter fraud. It could also radicalize American politics and lead to Presidents who are elected with very small pluralities, or who failed to qualify for the ballot in all 50 states and the District of Columbia.

A meta-analysis is a research technique for combining the results of all the published and even unpublished results on one question and drawing a conclusion based on the entire set of studies on the topic.

In many cases, researchers can combine many studies that have been done on one topic, and get an overall big picture view of how an intervention works compared to placebo or compared to another treatment.

It is a quantitative review of several studies with the goal of determining their combined effects on a topic of interest. This can provide more accurate and statistically significant results than just one study alone, and there are several different methods that researchers use to draw conclusions from meta-analyses.

The the benefits of using meta-analysis in your research, is  you can perform this analysis in Excel to maximize its usefulness in your own business research studies.
