Quiz Solution Q - 14

Food is limited on the Galapagos islands, so finches must compete for available food. Some birds have beak shapes that give them an advantage in feeding over others. These birds are therefore more likely to survive and pass the traits for these beak shapes to their offspring.

Check out the new resources!

In preparation for the honors test Friday, I have updated the Quizlet body systems quiz with more vocabulary. Check it out!

Let me also suggest you take a look at the link for old Regents exams on the right side of the page. Practice is a great way to improve, and practicing with a large number of test questions together with a focused review is going to go a long way towards helping you improve on tests.

As I have said in class...

  • Review actively! Practice writing questions and answering them. Send them to me and I will give you feedback!
  • Write down a plan for exactly how you will prepare. Note that I didn't say study - that word has the wrong connotation for most students!
  • Follow the "hand it in or show me" rule. If the work you do to prepare can't be handed in to me (on paper) or shown to me (as in a perfect score on Quizlet) then it isn't the right kind of work. 
Get it wrong - write out the mistake - repeat until you get it right every time!

Excretory System and (Oops, did I say Quiz?)

Just to reward those of you that check this site regularly, the honors section will be starting class with a vocabulary/structure quiz, including some questions related to disorders. If you know your disorders and circulatory/respiratory parts, you should be fine.

Fine, however, may not be good enough to get an A! If you want to be in great shape, I advise you to make a list of the important terms for each structure and quiz yourself.

Here is a link to a quizlet test:

Stem Cell Links

Stem cell technology is one of the most active areas in developmental biology. I hope that today's discussion leads you to explore more on your own.

Here are the links we used in today's lesson:

The animation describing differentiation and diseases that might be cured by stem cells can be found here.
