Endotherms - Study guides, Class notes & Summaries

BIO 100 Exam 3 Review Questions – ASU with Complete Solutions **Compare and contrast the roles of positive and negative feedback in maintaining homeostasis. Use these concepts to explain:** a. **Regulating blood glucose levels:** Negative feedback – the pancreas produces insulin to lower high blood sugar levels. b. **Formation of blood clots:** Positive feedback – initial platelets bind to the injury site, attracting more platelets to the area. **What does it mean for an organi...

Gametes sex cells Gene Combination of alleles Allele Piece of a gene ATP energy amino acids proteins Starch Sugar Endotherms warm blooded Ectotherms cold blooded Radiation Energy transmitted without contact between objects (usually in rays, waves, or particles) Convection Energy transferred through fluids Conduction energy transferred by direct contact of two objects Osmosis Water moves to equalize concentration

Convection - *Transfer of heat by movement of liquids and gases (Molecules of air or water next to warm surface gain energy and move away from surface)*When environment is cold, organism warms it's boundary layer which reduces heat loss but current of air can disrupt layer and carry away heat by convection (wind chill) Radiation - *Emission of electromagnetic energy by surface (i.e. sun) *When objects are warmed by radiation, they emit lower-energy radiation as infrared light *The temp of...

ANT100 EVO Exam Questions and Answers 100% Pass Problems limiting development of theory of evolution: - Answer- 1. Lack of knowledge on age of earth --> Bishop Usher stated that Earth was created at 2:30pm of October 23rd, 4004 BC - it was accepted because it was too dangerous to disagree w/ the church 2. Religious concept of fixity of species --> Thought God placed all animals on Earth in their current forms 3. Lack of scientific method --> Many ideas/concepts based on singula...

Where would Green Sea Turtle populations show the highest density? temperature - Answer-What is one of the most significant environmental factors contributing to the distribution pattern of manatees in Florida? plants, animals, except pest insects - Answer-The Endangered Species Act (ESA) passed in the United Sta...

Are lizards always "cold-blooded?" correct answers No, they move amongst microhabitats to keep their body temperature around the same level. What is the TNZ? Who has one? correct answers TNZ stands for thermal neutral zone. It is the temperature range in which the resting metabolic rate equals the basal metabolic rate. Endotherms have one. Is the metabolic rate of a mouse greater than that of an elephant? correct answers The metabolic rate of the mouse compared to its mass is much larger...

Arizona State University BIO 100 (Oberlin) Exam 3 Study Guide Rated A+ Compare and contrast the use of positive and negative feedback mechanisms in maintaining homeostasis. Illustrate these concepts with: • The regulation of blood glucose levels • The release of platelets to form blood clots. Negative feedback counteracts changes to maintain stability. For instance, when blood glucose levels rise, the pancreas secretes insulin, prompting the liver to absorb the excess glucose. Conve...
