Cоnsider the fоllоwing study аnd аddress questions 38-39 Reseаrchers set out to test the impact of Families First, a comprehensive program addressing parent employment and financial stability on participants’ children’s academic achievement and motivation, and school engagement. Researchers recruited 750 families between July 2008-December 2010. All parents had one or more children between ages 2 and 11 years old and were under-employed and/or low income (under 200% of the federal poverty level). Half of the families (375) were randomly assigned to Families First, and therefore provided with income supplements and important work supports including extensive child-care assistance and health care subsidies. The other half was assigned to a control condition (treatment as usual). At the 5-year follow-up study, when children of all families were between the ages of 7 and 17, researchers conducted interviews with parents, children and teachers. As hypothesized, in comparison to the control-group children, children of Families First families scored significantly higher on academic achievement and motivation to achieve. “Motivation to achieve” was measured in child interviews using 12 questions about perceived ability, expectations for success, and perceived value of studying math and English; responses could range on a 5-point scale from ‘not at all’=1 to ‘very’=5. Overall, the results of the study suggested that an income/employment intervention for families in poverty can lead to profound, long-term changes in children’s educational engagement outlook and achievement. ---------------------------------------------------- State the null hypothesis tested in this study.

Origins-of-life reseаrchers have hypothesized that a chemical reaction called phosphorylation may have been crucial for the assembly of three key ingredients in early life forms. What phosphorylating agent that was plausibly present on early Earth and could have produced these three classes of molecules side-by-side under the same realistic conditions was discovered in the article, Potential 'missing link' in chemistry that led to life on Earth discovered? (You can use the acronym)   What are the 3 classes of molecules that are able to be formed with this compound?
