You will be responsible for the Element if I give you the symbol or the symbol if I give you the element. ONLY elements 1-36 will be tested.


Quizlet has a lot of study flashcards if you google "Quizlet elements 1-36".

Point Mutations (usually happen during REPLICATION in S-stage of INTERPHASE)
(Macro) Chromosomal Mutations (usually during meiosis so the mutations exist in the egg or sperm)
Nondisjunction
Karyotyping
Cloning

The outstanding performer on this exam should be able to:
1) Define or explain the significance of all of these terms to the topic of genetics: trait, chromosome, gene, allele, inherit, genetic, Punnett Square, Gregor Mendel, dominant, recessive, homozygous, carrier, heterozygous, phenotype, genotype, codominance, incomplete dominance, multiple allele trait, sex-linked 
2) Perform any monohybrid cross of individuals when the directions use the terms you have learned and predicted the expected outcome of offspring. (genotypic outcome prediction, phenotypic outcome prediction)
3) Dispel myths about genetics and inheritance and explain the actual way things occur according to the evidence. (ex. "skipping a generation really just means that your parents were carriers of the recessive allele)

50 Point exam will require students to be able to:


1) Define or identify ALL vocabulary terms on your Mitosis AND Meiosis documents.
2) Compare and contrast Mitosis to Meiosis: goals, steps, details
3) Identify the stages of Mitosis OR Meiosis I & II simply by seeing a diagram of the cellular processes at that moment.
4) Identify the importance of chromosomes in cell division and how they work to ensure that SEXUAL reproduction occurs and DNA is different in each gamete.

Watch the attached video and complete the document attached on the process by which gametes are created to prepare for sexual reproduction: MEIOSIS

1) Please complete the Mitosis Slides labeling activity.

REPRODUCTION

Living things use lots of different strategies for producing offspring, but most strategies fall neatly into the categories of either sexual or asexual reproduction. Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Sexual and asexual reproduction have advantages and disadvantages—which is why some organisms do both!

Watch the video and complete the guide with the assistance of your teacher in class.

Worth 10 Points: There are 15 questions and 66% is passing!

The successful student on tomorrow's quiz should be able to:


1) define succession and  explain the difference between Primary and Secondary Succession using: pioneer organisms, intermediate growth, climax forest in their explanation.
2) delineate the reactants and products of photosynthesis (noting the overall goal of the process, where it occurs, how it gets the raw materials, and which organisms have the ability to do photosynthesis).
3) delineate the reactants and products of cellular respiration (noting the overall goal of the process, where it occurs, how it gets the raw materials, and that all cells, including plant cells, must do cellular respiration to make ATP energy).
4) clarify the necessary interdependence of producers and consumers as it relates to the oxygen-CO2 cycle in the atmosphere which fuels photosynthesis & cellular respiration.
5) identify the chemical formulas for the reactants and product of these processes. 
6) discuss BTB (bromthymal blue indicator) and its role in our Snail/Plant lab

STATE PSSA  OBJECTIVES 
ASSESSMENT ANCHOR
S8.D.1 Earth Features and Processes that Change Earth and Its Resources 


ELIGIBLE CONTENT


S8.D.1.1 Describe constructive and destructive natural processes that form different geologic structures and resources. 


S8.D.1.1.1 Explain the rock cycle as changes in the solid earth and rock types (igneous – sedimentary – metamorphic).


S8.D.1.1.2 Describe natural processes that change Earth’s surface.

The Earth is dynamic (ever changing) and the crust is constantly being broken down and rebuilt through a series of geologic processes.  Today we will investigate these geologic constructive and destructive processes and see their cause and effect relationship on Earth's surface features!

Do a graphic analysis to draw a conclusion for the inquiry question posed here in the title of your assignment.
