Exploring Life - Honors Biology Chapter 10

When you click Submit (at the bottom of this web page) it will save your work on the server for me. If you get a "proxy error" hit -refresh- until you get a "Thanks"

You might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers.

Since we may work on this over more than one day, I will keep track of what you have done. Feel free to click submit as you work to save your work to the server. 

DO NOT JUST LOOK FOR THE ANSWERS…YOU’LL MISS LOTS OF IMPORTANT STUFF. THE QUESTIONS ARE JUST TO KEEP YOU “HONEST.”

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

Since you will be working in groups, put all the names of the people in the group in the box. The ideal group size is 2. As an exception I will allow groups of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers. Group sizes above 3 will be penalized in the grading.

Remember, the boxes will expand as you type if you need more space.  Also remember that although some of the answers may only require a single word (or number) the box size is standard, don't feel you have to fill it. Answer the questions as given.

You can work on this from home once you have signed up for Successnet.

Open SuccessNet in a separate window . (If you need help with that ask.) Later you may want to open the Explore Life CD in a separate window  (If you need help with that ask.)

If you have already signed up for SuccessNet, you can access the assignment that way, and also work from home (or library).

While there are questions on the CD, they provide answers, so I can't grade their questions. You will get a grade for the answers on this form!

Q04. If you were to cross a hybrid tall pea plant (tall is dominant) with another hybrid tall pea plant and get 1000 seeds, how many of the resulting plants would you expect to be tall?

How many would expect to be homozygous tall (that is they would be pure breeding)? How many would be hybrid tall?
