As Jerry nears the campfire, he is delighted at the warmth it provides. Jerry perceives this temperature because of thermoreceptors in his skin.
<h3>What are thermoreceptors?</h3>
- The receptive part of a sensory neuron, or more precisely a non-specialized sense receptor called a thermoreceptor, is responsible for coding absolute and relative changes in temperature, primarily those that fall within a safe range.
- Warmth sensors are assumed to be unmyelinated C-fibers in the mammalian peripheral nervous system (low conduction velocity), whereas cold receptors have both C-fibers and sparsely myelinated A delta fibers.
- Warm receptors respond well to warming, which causes them to discharge action potentials more quickly.
- For cold sensors, cooling causes an increase in firing rate whereas warming causes a reduction.
- A paradoxical reaction to heat is when some cold receptors react to high temperatures, usually above 45 °C, by releasing a short action potential.

6.An egret eats insects stirred up by grazing animals. Which of these terms applies to the relationship between the egret and the grazing animal?Answer: commensalism
7. The concept that two species cannot occupy the same ecological niche simultaneously and continuously is called:Answer: the competitive exclusion principle
8. What is a serious problem that will result from predicted rises in global temperature?Answer: Species will be lost because rises in global temperature will exceed the rate at which natural selection can allow most organisms to adapt.
9. Why do most mutations occur?Answer: Random errors in DNA replication cause mutation.
10. What is the best definition of speciation?Answer: the process by which new species form
11. What is speciation resulting from two populations becoming isolated from one another?Answer: allopatric speciation
12.A scientific name is composed of two parts. What are they?Answers: genus and species
13. What is the smallest group that can evolve?Answer: population
14. A forest fire kills off 90% of a rabbit population. What has occurred in this population?Answer: bottleneck
15. How do founder effect, genetic drift, and a bottleneck relate to each other?Answer: Founder effect and bottleneck are types of genetic drift.
16. In the common phrase, "survival of the fittest," what determines how fit an individual is?Answer: reproductive success
17. Which postulate of natural selection is best supported by the work of Gregor Mendel?Answer: Traits are passed from parent to offspring.
18. What can you conclude by looking at the following sequences from the cytochrome c gene of humans, mice, and an unknown organism? Human - ATGGTCTCTTT Mouse - ACGGTCTGTTC Unknown - ACGGTGTGTTCAnswer: The unknown organism is more closely related to mice than to humans.
19. What conclusion can you make from comparing the bones in a bird wing, a bat wing, and a pterodactyl wing?Answer: These organisms share a common ancestor with each other.
20. When predatory snakes eat songbirds with the loudest songs, they are acting as agents of what?Answer: natural selection
Answer: 1. Energy drink
2. What people prefer to drink.
Explanation:
1.The independent variable can be referred to that variable that can be manipulated in an experiment. The energy drinks can be changed to see that what people prefer to drink.
2.The dependent variable can be referred to that variable which is the result of the experiment it is influenced by the independent variable. What people prefer to drink is the dependent variable.
3.The data being collected in this experiment will be quantitative. As we can calculate the response of people what they prefer to drink in numbers.
