In mammals, body temperature is controlled by a structure in the brain called the hypothalamus. The hypothalamus is able to sense even slight variations in body temperature. This structure is responsible for bodily responses that include thirst, the activation of sweat glands, and the dilation of blood vessels near the skin. Each of these mechanisms works to restore body temperature to a normal range.

Fearful that the child may have jaundice (a condition caused by bilirubin, a toxic yellow-orange pigment produced during the destruction of red blood cells), she takes him to her pediatrician. After examining the child and noting that his bilirubin levels are normal, the pediatrician declares him perfectly healthy and advises the mother to watch the child’s diet. Why? The other twin suffers from bluish coloration of this skin condition known as cyanosis (bluish tint). What can cause cyanosis? 2. Janine was taken to the ER for heat stroke and dehydration.

- One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as sensors to detect changes in blood glucose levels. High glucose levels cause beta cells to increase the amount of insulin given off by the pancreas. The insulin triggers body cells to take in glucose and the liver to store excess glucose as glycogen, decreasing the blood glucose level. On the other hand, low glucose blood levels trigger alpha cells to signal for glycogen to free up stored glucose from your liver, thus increasing the blood glucose level. (4 points) 1. What type of feedback mechanism is this, positive or negative? Explain your answer based on the description of the mechanism. Blood glucose levels change throughout the day. Explain what causes these changes and describe how these feedback cycles work together to maintain a dynamic homeostasis. III. Predict what will happen to this feedback mechanism and then to a person's body if the beta cells…arrow_forwardA group of students are participating in a 24-hour fast to raise money for the foodbank. Fasting refers to refraining from eating for a period of time. Select the answer that describes how the students’ bodies would respond to maintain homeostasis. Select one: a. The beta cells of the islets of Langerhans are producing glucagon to decrease blood glucose levels. b. The alpha cells of the islets of Langerhans are producing insulin to increase blood sugar levels. c. The alpha cells of the islets of Langerhans are producing glucagon to increase blood glucose levels. d. The beta cells of the islets of Langerhans are producing insulin to decrease blood sugar levels.arrow_forwardSome nutritionists claim that the secret to long life is to be slightly underweight as an adult.

- People with bulimia have elevated ghrelin levels. Is this abnormality a likely cause of bulimia? And what is the evidence? a. No. It is probably not a cause. The abnormality is common in the ethnic groups who are most likely to develop bulimia. b. No. It is probably not a cause. As people recover from bulimia, their ghrelin level returns toward normal. c. Yes. It is probably a cause. People who show high ghrelin early in life are likely to develop bulimia later. d. Yes. It is probably a cause. Inducing high ghrelin in rats causes the rats to develop bulimia.arrow_forwardHello, here is my question : A boy returns to school after summer vacation to begin 7th grade only to find that he is at least four inches taller than several classmates that were the same height as him before the summer.

Soon afterward, obesity and type 2diabetes became common. (A genetically related group,Pima Indians in Mexico, who live in remote mountain villagesand maintain the diet and activity levels of their ancestors,have a low rate of diabetes and obesity.) Researchers havediscovered that IRS1 levels are reduced in obese individualsfrom the Arizona Pima population, as compared with leanindividuals. It was also shown that specific mutations inthe IRS1 gene in combination with obesity led to a 50% reduction in insulin sensitivity. Explain this phenomenon.arrow_forward
- When the body is in a state of "dis-ease" the systems in our body do not function the way that they do when we are in a state of "ease". In a study of two adult twin sisters age 54, Beth and Mary, scientists were trying to understand why these twins had very different body weights and why Mary was suffering from a gastrointestinal disease yet her sister was healthy. They studied the healthy twin (Beth) to see if they could learn anything about her sisters disease from studying her. They were raised in the same house until they went to different colleges (Beth stayed in London and Mary lived along the coast line in a farm town in France). They were both mostly healthy throughout their childhood although Mary had a very sensitive stomach and suffered from allergies. Through the use of questionarres, stool samples and genetic samples the researchers learned so much about the two sisters, including that Beth was born vaginally but Mary was born by C- section because their mom was to…arrow_forward1.
