Science 9 Test

DNA, Mitosis, and Meiosis Test Notes

Nucleus and DNA
-DNA structure: what is the backbone made of, what are the four nitrogenous bases, how do they join?
-DNA code: what is the purpose of the nitrogenous bases matching? Can you copy the other side of a code?
-tell the difference between chromatin and chromosomes.
-what do genes tell the cell to make? What are some examples?
-the role of DNA, RNA, and ribosomes in protein production done
Cell Cycle and Mitosis
-what are the stages in the cell cycle, which one is the longest, what is interphase, what does G0 mean?
-identify stages of mitosis, order stages of mitosis, describe stages of mitosis
-know terms: sister chromatids, nuclear membrane, centrioles, centromeres, chromosomes, mother cell, daughter cell
Asexual Reproduction
-5 kinds of asexual reproduction with examples and basic descriptions of how they work
-what is mitosis for besides reproduction?
-how does cancer work and why can't we cure it completely?
-what are the advantages and disadvantages of sexual reproduction?
Sexual Reproduction
-what do haploid and diploid mean?
-describe sexual reproduction including the terms: gamete, egg, sperm, diploid, haploid, fertilization, zygote.
-where does variation come from in sexual reproduction
Meiosis
-identify stages of meiosis, order stages of meiosis, describe stages of meiosis
-know terms: sister chromatids, homologous chromosomes, independent assortment, nuclear membrane, centrioles, centromeres, chromosomes, mother cell, daughter cell, gametes
Fertilization

Describe and compare external and internal fertilization

This is a good link for evolutionary terms: https://www.ck12.org/book/CK-12-Biology-Concepts/section/11.2/ If you have: annelids, cheliceriforma, hexapoda, and crustacea Phylums are : annelids and arthropods (cheliceriforma, hexapoda, crustacea) -could talk about segmentation, exoskeleton, moulting, last common ancestor, chilicerae,    biramous  appendages. terrestial and aquatic, number of legs http://evolution.berkeley.edu/evolibrary/article//arthropods_02 https://en.wikipedia.org/wiki/Arthropod#Evolutionary_family_tree  go to "evolutionary family tree" and "classification" ---------------------------------------------------------- If you have: Porifera, Cnidaria, Platyhelminthes, Nematoda All four are their own phylums  -could talk about multicellularity, symmetry, tissues, body cavity, acoelomate, coelomate, germ layers Use evolutionary tree -  https://www.ck12.org/book/CK-12-Biology-Concepts/section/11.2/ \ --------------------------
