The cell cycle consists of interphase, mitosis, and cytokinesis. 35. During interphase, the cell grows and duplicates its DNA in preparation for division. 36. The first phase of mitosis is prophase, during which the chromatin condenses into visible chromosomes. 37. The structure that helps separate chromosomes during mitosis is called the spindle fibres 38. During metaphase, chromosomes line up at the middle of the cell. 39. In anaphase sister chromatids are pulled apart to opposite ends of the cell. 40. The final phase of mitosis is telophase, during which a nuclear membrane forms around each set of chromosomes. 41.

No AJ wear protective clothing Matter dean up your work station.  Wash your hands Can it be physically separated? pure No substance homogenou s mixture heterogenou s mixture Solutions Suspensions Colloids alloys. Yes Can it be chemically decomposed? compound No  element Short Answer Section 1: BIOLOGY 1. Some human cells, such as muscle cells, have more mitochondria. Why would these cells need more mitochondria? (2pts) Mitochondria make energy for the cell (ATP). Muscles are active, they need more mitochondria because they use more energy. 2. Photosynthesis creates sugar for the cell. What organelle does the sugar need to go to next and why? (2 pts) Sugar will need to get used or stored. If it gets used it will go to the mitochondria. If it gets stored then a vacoule (or maybe a starch granule) 3. Why are vacuoles in plant cells many times larger than vacuoles in animal cells? (2pts) Many possible answers. ex:// Plants can not move to search for water so they have to store more incase of drought. 4. Compare and contrast RNA and DNA option s  DNA -double stranded -ATCG -deoxyribose sugar -one type RNA -single stranded -AUCG -ribose sugar -3 types (mRNA, Erna, rRNA). 5. Some textbooks call interphase the "resting phase" of mitosis, but the cell is far from resting in this phase. What happens during interphase? growth repair replicating DNA replicating organelles making protein's performing cell functions 6. Why don't spinal cord and brain injuries heal? These cells get stuck in interphase. They never go through mitosis so they can not repair.  7. What does it mean when someone talks about offspring in terms of "nature vs nurture"? Nature - genes affect who you are Nurture your environment affects who you are. They both shape you into the person you become. 8. Explain 3 ways plants are pollinated? @wind carries pollen through the air Water can carry pollen through droplets falling. 3 Insects carry pollen while searching for nectar. Animals carry pollen on their for 9. What is crossing over and why is it so important? Process in prophase 1 where genes are exchanged between maternal and paternal chromosomes. It leads to variation in a species. Short Answer Section 2: CHEMISTRY 1. What should you do if you get a chemical in your eye while completing a laboratory procedure? Tell your teacher/instructor. Need to flush the eye, use the eyewash station at the front of the lab. 2. Why is it important to know the location of the fire extinguisher and first aid kit in the laboratory? Fire estinguisher can be used to put out anything Flammable that catches fire. First aid kit is used to tend to minor incidents like cuts or scrapes. 3. What are the three main parts of an atom? Their charges? And location? Part of Atom Charge 1. proton positive 2. neutron ncutra! 3. electron negative Location nucleus nucleus shells or cloud. 4.

Determine whether the following statement refers to qualitative data, quantitative data, or some combination of these (5 pts): 1. Mrs. Smith gave a test on which the maximum possible score was 100. The actual scores students received were 92, 87, 86, 85, 72, 70, 70, and 61. quantitative 2.

Just physical change does not create a new substance. physically changes it like size or shape. May be  reversed. ex:// cutting paper. chemical change creates a new substance and can [not be reversed ex:// burning paper (smoke & ash). For each of the following changes, identify it as a physical or chemical change. 1) Cracking an egg = physical change 2) Brushing your hair = physical change 3) Fireworks exploding = Chemical change 4) Digesting your lunch = chemical change 5) Iron rusting =_chemical change. 1. You cut a piece of paper into small pieces. Is this a physical or chemical change? Explain your answer Physical Change Paper is cut into pieces. It just chang size. Molecules have bot rearranged. No new substance formed. 2. You find a nail on the ground in the parking lot, in a small puddle of water. Rust has formed on the outside of the nail. Was this a physical or chemical change? Explam your answer. Chemical change. Molecules have rearranged because rust rust has formed on the nail. A new substance.
