Professor James Do you have a minute?
Sure Come on in What can I do for you?
Well, I did pretty well on the midterm
You sure did One of the best grades, as I recall
But I missed a question, and I'd appreciate it if you could help me understand what I did wrong I have the test right here, and I just cant figure it out
Okay Fire away
It's question 7 the one on biotic provinces and biomes
Oh, that one Urn, quite a few people missed it I was thinking that we should go over it again in class But anyway, let's look at your answer
Thanks Here's the thing I said that a biotic province was a region with similar life but with boundaries that prevent plants and animals from spreading to other regions So an animal, for example, a
mammal it may have a genetic ancestor in common with another mammal But a biome is a similar environment, an ecosystem really, like a desert or a tropical rainforest So, in the case of a biome, well, the similar climate causes the plants and animals to evolve to adapt to the climate, and that's why they look alike
That's good, very good as far as you went But there's a second part to the question Look, right here, "Include an explanation of convergent and divergent evolution.” So … I was looking for a more complete answer Next time be sure to include both parts of a question … when there are
two parts like this one … Do you know how to explain convergent and divergent evolution?
I think so Isn’t it … like when a group of plants or animals … when they’re separated by mountains or a large body of water … then subpopulations evolve from a common ancestor and they have similar characteristics but their development diverges because of the separation, so that’s why we call it divergent evolution
Right Even when the habitat is similar, if they're separated then they diverge … How about convergent evolution then?
Well, that would be a situation where a similar environment a habitat it may cause plants and animals to evolve in order to adapt to the condition So a species that isn't really related can evolve with similar characteristics because it can look like a species in another geographic region because of adaptation and that would be convergent evolution?
Right again So temperature and rainfall, proximity to water, latitude and longitude all combine to determine the climate, and if we know the climate of an area, then we can actually predict what kind of life will inhabit it
Okay And I really did know that I just didn't put it down To tell the truth, I didn't see the second part Not until you pointed it out to me
That's what I thought Well, Jerry, it's a good idea to double-check all the questions on a test not just
my test any test to make sure you've answered each part of the question completely Otherwise, you wont get full credit
I see that Weil, live and learn Jerry, you're one of my best students Thanks I really like biology In fact, I'm thinking of majoring in it
Good That means you'll be in some of my upper-level classes
And I'll be watching out for those two-part questions on your exams
Trang 2Student (Q5)
Professor
And all the rest of your exams I’ll be honest with you My questions usually have two parts so the students will have an insight into the grading system and a lot of professors do that In an essay question, it's difficult to know what to include and how much to write Just read the question carefully, and be sure to include all the parts There may be three or four in some essay questions This is the way that the professor helps you organize your answer I am giving my students a hint about what I am looking for by including several parts to the question But if you miss one of the parts, then it lowers your score
That makes sense, I think I was just trying to finish within the time limit, and I didn’t read as carefully as
I should have On the final, I’ll spend more time reading the questions before I start answer them Good plan
