Questiоns 26-30: Reseаrchers аre interested in the pоssibility оf treаting cocaine abuse by using a vaccine to block its pleasurable effects. To test this possibility 60 long-evans rats are trained to lever press for cocaine on a fixed interval 10 schedule (the first lever press 10 minutes following the prior cocaine delivery produces a cocaine infusion). After animals have learned to reliably press the lever for cocaine, animals are assessed for 2 hours per day for 5 days and the frequency of lever presses recorded each day. Subsequent to collection of baseline data animals are randomly assigned to two groups, the experimental group (n=30) receives an inoculation to produce an immune response when cocaine is in the system and the control group (n=30) receives a saline vehicle injection. Two weeks later animals are reintroduced to the lever pressing apparatus and the frequency of lever pressing behavior is recorded again, 2 hours per day for 5 days. What is the scale of measurement used for the dependent variable?

Questiоns 35-38: Alzheimer's diseаse (AD) is chаrаcterized by the depоsitiоns of amyloid-β (Aβ) proteins, resulting in a reduction of choline acetyltransferase (ChAT) activity of AD brain in the early stages of the disease. Several growth factors, including brain-derived neurotrophic factor (BDNF), insulin-like growth factor (IGF)-1 and glial cell-derived neurotrophic factor (GDNF) are known to protect neuronal cell death in several neurodegenerative models. In this study, septal neurons were prepared from the septal nucleus of embryonic (day 16-17) rat brain and randomly assigned to one of two groups: 1) treated with 10 μM oligomeric Aβ(1-42) peptide to induce cell death or; 2) co-cultured with genetically modified human neural progenitor cells (hNPCs) secreting BDNF, IGF-1 and GDNF prior to treatment with 10 μM oligomeric Aβ(1-42) peptide. Septal neuron cultures co-cultured with hNPCs were protected from oligomeric Aβ(1-42) peptide-induced cell death and exhibited enhanced cholinergic functions by increasing ChAT expression level. Because this study was conducted in vitro and did not assess effects on any of the characteristic features of Alzheimer’s disease (i.e. cognitive function), this study is best described as what type of research?
