Show the genetic makeup of 2 parent pea plants that would result in 100 % white flowers in the offspring. __________ x _________ 5. If a pea plant that has two genes for round seeds (RR) is bred with a pea plant that has two genes for wrinkled seeds (ww), what can you predict is the probability of each offspring having wrinkled seeds? Write the cross here ________ X _________ Show the Punnett: _____% wrinkled _____% round 6. Cross a tall pea plant (Ts) with a tall pea plant (Ts), and predict the outcome: _______ % Tall pea plants _______ % short pea plants Complete the chart Type of reproduction Fission Sexual or asexual Description or sketch Conjugation Budding Regeneration Fertilization Using the pictures of the phases of mitosis, answer questions 1-6 1. 2. 3. 4. 5. 6. 7. ______ chromosomes are doubling ___+___ parent cell resting ______ cell membrane forming between 2 daughter cells ______ 2 new daughter cells formed ______ chromosomes pulling apart to the poles of daughter cells __________________ name a cell in your body that performs mitosis If cell A has 12 chromosomes, how many chromosomes are in cell C? ______ ….. how many in each cell in F? _____________ 8. Identify this process: _______________________ This chart compares the creation of a body cell to the creation of a reproductive cell. Fill in the information. Body cell Reproductive cell Name some: Name of process where cell is created For human, # chromosomes in each For human number of pairs of chromosomes in each Sketch the process 1. In what cell part does photosynthesis occur? _____________________ 2. Identify 2 things that the plant needs from the environment to perform photosynthesis. a) b) 3. What function is the root performing for photosynthesis to occur? ______________________ 4. What gas is used by the plant to make glucose? _________ 5. What gas is excreted by mice when using sugar to make energy? ______________ DESIGNING AN EXPERIMENT: CONTROL AND VARIABLE Use the following picture to answer the questions. 1. Write a hypothesis for what this illustration is testing: 2. Identify the control: ________________________________________ 3. Identify the independent variable: _________________________________ 4. Identify the dependant variable: ___________________________________ 5. What are three constants that need to be kept in the above experiment? Note the constant along with the scientific reasoning for keeping that constant in the experiment. CONSTANT SCIENTIFIC REASON FOR HAVING THE CONSTANT 6. Amy decides to add fertilizer to the first and last dish of seeds. Discuss how this would impact her results. (Are they valid? Why or why not) Use the picture to answer the questions. 1. Identify a a. Producer: b. Consumer: c. Decomposer: 2. Sketch a food web using at least 7 organisms 2. Create an energy pyramid using organisms in the picture. 3. On the pyramid, indicate the level of energy available at each level, if the producer has 100% at its level. 4. 5. 6. 7. What is the source of energy driving the energy pyramid? _____________ An herbivore eats _____________ An omnivore eats ______________ A carnivore eats _______________ Name _________________________ State Science Assessment Review 1. The film on the overhead shows the light as it appears using the low power objective lens on the microscope. The grid is a piece of graph paper with squares that are 1mm x 1mm. What is the diameter of the field of view for a. ___________ b. ____________ c. __________ 2. To figure out how long something is under the microscope, you determine the diameter of the field place the specimen so it is lined up with the left side of the ocular determine how far it goes across the field (25%, 50%, 75%, 100%) multiply the distance covered (%) times the diameter of the field (round to nearest hundreth) record with mm as units. 3. How long is the following, if you are using each scope (a,b,c from above) Object under the scope Scope diameter (see #1) Length of object Use scope C Length from head to measurement: ________ abdomen = __________ Use scope C Length from bumper to measurement: ________ bumper: ____________ Use scope C measurement: _______ Length of piece of lemon : ____________ Using your microscope a) focus on the see through metric ruler b) line up at mm marking to the left of the diameter c) count the number of whole and amount of partial mm that run through the middle (diameter) of your field of view d) record the diameter of your field of view under LOW power: Teacher check_____________ Return the ruler and get a slide with a letter on it. What is the letter on your slide? _________ What is the width or length of the Specimen on your slide ? Teacher check_____________ http://www.stanford.edu/group/Urchin/m-size.htm 1.. In the large box at the top of the Sorting Chart there is the question, "Does this creature have legs?" Separate the creatures into Box 1 and Box 2 according to the answer to this question. DO NOT WRITE ON THE SORTING CHART Does this creature have legs? ABCDEF 1 Yes 2 No RECORD THE LETTERS IN THE BOXES 2. For the creatures in BOX 1, create a question that would separate them into either BOX 3 or BOX 4. Your question must result in at least one creature being placed in Box 3 and one creature being placed in Box 4. Your question must be based on the creature's observable structure. (DO NOT USE color, size, or material it is made of). Record your question here. 3. Separate the creatures from BOX 1 into either BOX 3 or BOX 4 according to the answers to your question in #2. Record the letter of each creature that you put into BOX 3 and BOX 4 in the space below. DO NOT WRITE ON THE SORTING CHART. 3 Yes 4 No 4. Now look at the creatures you have placed in BOX 2. Create a question that would separate them into either BOX 5 or BOX 6. Your question must result in at least one creature being placed in Box 5 and at least one creature being placed in Box 6. Your question must be based on the creature's observable structure. (DO NOT USE color, size, or material it is made of). Record your question here. 5. Separate the creatures from BOX 2 into either BOX 5 or BOX 6 according to the answers to your question in #4. Record the letter of each creature that you put into BOX 5 and BOX 6 in the space below. DO NOT WRITE ON THE SORTING CHART. 5 Yes 6 No
