Close Toed Observation
Safety/Science Foundations
1. Avoid the situation; don't touch
2. Close-toed shoes
3. Students
4. To protect your eyes from chemicals
5. Before starting the lab
6. Students should not play around and follow directions. Students should clean up after their selves after finishing a lab.
7. Hypothesis - a testable explanation for an observation
8. Observation - statement made using senses. ex. I hear chirping
Inference - interpretation from observations. ex. "The chirping is from the bird"
9. Biology - study of life
10. Organization, reproduction, growth, use energy, respond to stimuli, maintain homeostasis, adapt and evolve
11. Homeostasis - balance/stability
12. Law - An independently and sufficiently verified description …show more content…
Valence electrons are involved in chemical bonding
17. a) 15, 15, 15 b) 18, 18, 22 c) 20, 20, 20 d) 8, 8, 8 e) 6, 6, 6 f) 7, 7, 7 g) 1, 1, 0 h) 3, 3, 4
18. Protons, neutrons, electrons
19. All matter is composed of small, fast moving particles called atoms
20. Ionic - two or more valence electrons are given or lost between both atoms (usually metals lose and nonmetals gain)
Covalent - two or more valence electrons are shared between both atoms
21. Base - a compound with more Hydroxide ions (OH-) to form a solution with a pH greater than 7/anion
22. Acid - a compound with more Hydronium ions (H3O+) to form a solution with a pH less than 7/cation
23. 0 - 6 = acids, 7 = neutral, 8 - 14 = bases
24. Help maintain homeostasis within an organism by keeping pH at a nearly constant value
25. Unequal sharing of atoms
26. a) Adhesion - "water gripping to something else" b) Cohesion - "water gripping to water" c) Capillary Action - adhesion + cohesion working together d) Solubility - amount of a substance (called the solute) that dissolves in a unit volume of a liquid substance (called the …show more content…
EX. Protists, fungi, plants, animals
72. Animal
73. Prokaryote, bacteria
74. Cell membrane
75. Golgi apparatus
76. Mitochondria
77. Ribosomes
78. The cell membrane controls conditions inside the cell as outside conditions change, selectively permeable - controls what goes in and out.
79. Nuclear membrane
80. Genetic material (DNA), Ribosomes, Cell membrane, Cytoplasm/cytosol
81. Differences: Plant cells have cell walls, plant cells have central vacuoles, there are more lysosomes in the animal cell than the plant, plants undergo photosynthesis for the production of energy, animal cells undergo cellular respiration for the production of energy
Similarities - Eukaryotic cells have a nucleus, goes through cell division; have the main organelles for protein synthesis
82. Chloroplast
83. When a substance moves from a high concentration to a lower concentration
84. Passive transport of materials across cell membrane by carrier proteins embedded in the membrane
85. Facilitated diffusion, diffusion
86. Endocytosis, exocytosis
87. Central vacuole
