Chapter 20, Problem 11TYK
Summary Introduction
To derive: A hypothesis to explain the effect of ice-cold water on the rate at which our body returns back to its normal temperature and also test this hypothesis.
Introduction: The temperature of body rises when someone comes after a long run. Homeostasis is operating under such circumstances for the regulation of temperature in the body. Hypothalamus of the brain maintains the temperature of the body. Homeostasis is mainly dependent on the negative feedback mechanism. When the temperature of the body rises, the hypothalamus senses the increase and reduces body tempearature by activating cooling mechanisms. For example, the secretion of sweat is a cooling mechanism.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant
women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their
pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants:
One group take the real medication intended to reduce heartburn, while the other group take placebo
medication. In this study what are:
Independent variable:
Dependent variable:
Control variable:
Experimental group: "
Control group:
If the participants do not know who is consuming the real pills and who is consuming the sugar pills.
This study is
It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months.
The researcher throws out the data from subjects that drop out. What type of bias is there in this study?
If the company who makes the medication funds this research, what type of bias might exist in this
research work?
How do I determine the inhertiance pattern from the pedigree diagram?
