Biology Keystone Review Packet 10th / 11th Grade Keystone Test Prep ●

This packet contains helpful information for you to prepare for the upcoming Biology Keystone Test on
May 15th and 16th . As you will see, this packet is broken down into several major themes that the
Keystone Test will cover. You will be assigned to do parts of this packet over the next several days for
a grade. Please take the time to read through and complete each section with your best possible
efforts. The preparation you put into this packet and trying to “re-learn” the material will benefit you
as if you do well on the test this time, you will not have to take it again. If the score of the test does
not meet expectations of the state, the test will need to be taken again. So this is a big deal. We all understand that you still have your regularly scheduled science class and that this is a lot of
stuff coming at you (again) in a short amount of time, but we are confident that we can do this
together. Refresh your biology memories, advocate for yourself with a science teacher if you do not
understand concepts or ideas, put forth a solid effort in completing the tasks and learning the
material…it can be done! Major themes covered in this packet: Themes of Life Organic Chemistry Cells and Cell Transport Energy Cell Reproduction & Genetics Protein Synthesis Evolution/Phylogeny Ecology Each section will have major vocabulary words that you should be familiar with, the major content
anchors that you should be able to answer questions about, some questions that will refresh your
memory and then some practice test questions. A wikispace has been set up to help you be successful in relearning the material. The address of the
wikispace is www.udkeystone.wikispaces.com – use this to your advantage. Your teachers have worked
very hard to help you – now it is your turn. Cell Reproduction & Genetics Vocabulary Al

Most likely chromosomes would fair to separate during anaphase I or Anaphase II. In
anaphase, chromosomes (anaphase I) or sister chromatids (anaphase II) are supposed to
separate, or move AWAY from each other. This is called Nondisjunction.

During meiosis cells and the genetic material is divided twice (the first set of division is
meiosis I and the second set is meiosis II). In mitosis, the cell and chromosomes divide
once.

Due to the improper number of chromosomes, the organism has an improper amount of
genetic material in the form of DNA of the sperm or egg. This mutation will be found in
every cell of the organism‛s body.
If chromosomes fail to separate during mitosis, it does not affect the sex cells but a
body cell. This mutant body cell then can be reproduced and produce more of the abnormal
cells. The cell either dies or is replicated quickly. This could possibly lead to cancer if the
cells are not destroyed by the immune system.
