The specific temperature of the performance curve differs with species. The curve can be determined by chronic or acute changes, it depends on research objectives. Ur(cid:448)i(cid:448)al ti(cid:373)e is li(cid:373)ited if it (cid:272)a(cid:374)"t get its shit together: elevation of body temperature becomes lethal. Low temperatures in an environment can weaken populations by making them less competitive, i. e. vulnerable. Theory of oxygen and capacity limited thermal balance: rising temps create o2 limitations. Exposure of certain tissue to narrow temp ranges may make them specialized at that temperature (through evolutionary change) Tissue function in lizards seems to peak when @ preferred temp, supporting this theory. Entire systems (hearing, digestion, immune) perform optimally @ preferred temperature some traits are not specialized, but thermoregulation and tissue specialization seem to evolve together. Fish in polar environments have a higher resting mr due to changes that allow them to thrive in sub- zero temps.

For the first part, you will write three different effective learning objectives focusing on insects that will support the standard from your discussion. For the second part, you will search for an existing insect-based lesson plan on the internet. Identify the standards addressed in that lesson and re-write your own learning objectives for the lesson plan.

Things to remember about learning objectives:

Learning objectives are brief descriptions of specific things a learner completing the lesson will know or be able to do. They should be succinctly expressed using clear action verbs.

The text of effective instructional objectives includes three parts. These parts are best described in the work of training and human performance expert Robert Mager:

description of a performance - Question to ask when writing this part: What do I want students to be able to do? The performance must be observable so be specific (E.g., Don't simply state students will understand something. You can't observe that. Students will define in writing, sort insects into groups by order, etc.).

conditions - important conditions under which the performance is expected to occur Examples: Given a list of... (sort into stacks); when provided with standard tools... (construct a table); without using references... (know the state capitols) Questions to ask when writing this part: What are the important conditions or constraints under which I want them to perform? What the learner will be provided? What will the learner be denied? Are there special conditions which occur on the job or when performing?

criterion or standard - the quality or level of performance that will be considered acceptable. Examples: include measures of speed (in less than 30 minutes...), direction (according to manufacturers specifications...), accuracy (without error...) , quality (all cuts must be smooth to the touch). Question to ask when writing this part: How well must learners perform for me to be satisfied they've accomplished the objective?

Part 1 must include:

1.The grade level, the Big Idea/Supportive Idea, and Next Generation Sunshine State Standard (5 points).
2. Three effective learning objectives (see advice above) that focus on insects and support that standard (5 points a piece).

Part 2 includes:

1.A working link for the lesson plan (2 points).
2. The grade level, the Big Idea/Supportive Idea, and Next Generation Sunshine State Standard (3 points).
3. Three effective learning objectives that focus on insects and support that standard (5 points a piece).

Which one of the following examples could serve as an example to illustrate what is meant by "norm of reaction"?AnswerIn some reptiles, sex-type is determined by the egg-incubation temperature. For some species, eggs with the same genotype developing at higher temperatures develop into a different sex type than eggs with that genotype developing at lower temperatures.In birds and some moths, males develop if embryos have two Z chromosomes and females develop if they have a Z and W chromosome.In ants and bees, diploid individuals are typically female while most males arise from unfertilized haploid eggs.In humans, XXY individuals are Klinefelter males.

1. Describe how you would test the hypothesis that the smallisland and the main island flies are separate species under thephylogenetic species concept. Be as specific as possible about themethods, sampling, etc. You can collect the materials on theislands and do any additional work after being rescued. Show whatyour results would look like if the two sets of flies weredifferent species AND if they were not.

2. Describe how you would test the hypothesis that the smallisland and main island flies are separate species under thebiological species concept. Be as specific as possible about theexperimental methods, sampling, statistical tests, etc. Again, youcan do this work after you are rescued and have access to thenecessary resources so donï¿½t be limited.

3. Assume that the flies meet the necessary criteria discussedabove (i.e., Biological or Phylogenetic species concepts) to beconsidered distinct species. What is the most likely geographicmode of speciation (be specific)?
