Textbook Question
Chapter 16, Problem 28CTQ
A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study?

Why is Drosophila melanogaster a relevant model of substance abuse disorders? Select all that apply. Partial point deduction for incorrect choices.
The fruit fly lacks dopaminergic neurons, making it a good negative model for addiction.
Because flies do not display dose-dependent responses to psychoactive drugs, fewer experimental treatments are needed.
The fruit fly has a homologous circadian clock, which can be manipulated to investigate changes in physiological responses to drugs.
Fruit flies are deuterostomes.
Several fly genes responsible for level of ethanol sensitivity have human orthologs.
The fruit fly also has neuropeptides secreted by brain cells that influence preference behaviors.
Imagine that someone had a particularly rough childhood but does not experience many more symptoms of depression than
someone who grew up in a more nurturing and stable environment. What can we likely conclude about this person?
O They have two long alleles of the dopamine transporter gene
O They have at least one short allele of the dopamine transporter gene
O They have two short alleles of the serotonin transporter gene
O They have at least one long allele of the serotonin transporter gene
Explain why does only male mice used for testing behavioral studies, why not include the female mice and it is important to use both sex of mice for behavioral studies?

A research study examined the blood serum levels of oxytocin in patients who have Type 2 diabetes and those with normal blood glucose levels. Each group was then subdivided into normal weight patients and obese patients. The levels of oxytocin were found to be lower in the obese patients with Type 2 diabetes than in the normal weight patients with normal blood glucose levels.

The researcher wants to conduct a study to understand risk factors for diabetes in this population. They design a randomized controlled trial where children will be assigned to one group in which they are given 8 glasses of sugar sweetened beverages (SSB) per day (treatment group) and one group in which they are given 8 glasses of water per day (control group). The researcher goes to elementary schools in under resourced neighborhoods and approaches children as they are leaving the campus to tell they they have to participate in the study. The students are not told anything about the potential risks or benefits of study participation and are not compensated for being in the study. Drinking 8 glasses of water per day is known to be better for health compared to drinking 8 glasses of SSB per day. Because one treatment is already known to be more…arrow_forward
