Biology Finals (9th_
| Where are assignments written down? Google classroom or white board. | |
| Does McAleer round? No | |
| Incomplete assignments earn how many pts.? 1 | |
| Where do you get missed work? The bins under the TV. | |
| What are Mac | a |
| How much are they worth? 1 Point. | |
| Where do you turn stuff in? In the black drawers in the southeast corner of the room. | |
| Independent/Dependent variable questions | |
| Know the scientific method. Observing, questioning, hypothesis, experiment, analysis and conclusion. | |
| Know independent, dependent, and constant variables. The dependent variable relies on the independent variable; it’s what happens as a result of the independent variable. A constant variable is a variable that stays the same throughout an experiment, etc. | |
| Know hypothesis, theory, law, constants, control/experimental groups | a hypothesis is a testable guess; a theory is a well |
| Know the basic units for length, volume, mass. | L, meter, v, liter, m, gram |
| Countries that don’t use the metric system | Liberia, Myanmar, US |
| Know how to measure with mm,cm,m,dm. | |
| Metric conversions | KHDUDCM, Kilo, hecto, deca, unit, deci, centi, milli |
| Know how to measure area and volume | Area, b x h, Volume l x w x h, |
| Know metric time, temperature and how to convert between °F and °C and vice versa | (32F-32) x 5/9 = C. C x 1.8 + 32 = F |
| Levels of ecological organization (p.7) Organism, population, community, ecosystem, biome, biosphere. | |
| Biotic/Abiotic factors | Biotic factors are living. Biotic factors are living, abiotic factors are not living. Sunlight, rocks, water or air. |
| What are the main bioregions? Tropical forest, grassland, desert, temperate forest, chaparral, boreal forest, tundra | |
| Understand how the atmosphere cannon works. | The atmosphere cannon had all the air sucked out of the tube with the pong ball inside, making it a vacuum. Once the mylar that was covering both sides of the tube gets punctured, the air forces in (b/c it needs to equalize the low air pressure inside the |
| Earth’s surfaces (light bulb) lab | what did we do? We measured how fast sand, dirt, and water heated up. Water heats up slowly and cools down slowly, soil heats up fast and cools down fast, sand heats up fast and cools down slower than soil, but fast. |
| Big bear is high up in the mountains, so the temp decreases. It’s cold, and the pacific ocean evaporates water and that water vapor rises up to the mountains. Because it’s cold, the water vapor cools and condenses into clouds and then those water droplets | |
| Big Bear gets snow because it’s high up, the air there is cold, and water vapor from the ocean cools and freezes as it rises | |
| Why does a chip bag inflate when driving up in elevation? Chip bags inflate because the outside air pressure decreases at a higher elevation, while the air inside the bag stays at the same pressure. The bag expands or inflates to balance the pressure dif | |
| Life supporting conditions on Earth | |
| Ch.2 | |
| Explain predator/prey relationships between moose and wolves on Isle Royale (p.47). There was an increase in foliage, which allowed the moose population to increase because they were eating more. Because there were more moose, the wolves were able to hunt | |
| Coyotes and Jackrabbits lab | Same thing as isle royale. Jackrabbits, with the absence of predators, populated. If the coyotes eat too much, and the jackrabbit population declines, they have less to eat and starve, which means they decline. It’s a dependent relationship. |
| Population growth curve (p.44) J | shaped curve, which symbolizes exponential growth. It’s where a population starts off slow but grows faster and faster. It has optimal conditions and unlimited resources. S |
| Density Independent/dependent limiting factors. Density dependent limiting factors are factors that depend on the population density (competition, disease), while density independent limiting factors don’t depend on any density. It kills at random. (Natur | |
| Population distribution, range (39), fluctuation, growth curves(44), carrying capacity (45), limiting factors(p.47), and ecological organization(p.7) Population distribution: Uniform, random, clumped. | |
| Carrying capacity | how much organisms an environment can support. |
| Limiting factors: Scarcity of food, water, predation, disease and parasites, sunlight, how much space there is, extreme heat, cold, floods, natural disasters. | |
| Polar Bears – seasonal limiting factors – why do they have to wait so long for their first meal of the season? Because they have to wait for the salt water to freeze over (salt water lowers the freezing point) so they can walk on the ice where the seals a | |
| Know all about Penguins, Sea otters, lionfish, rabbits, and urban coyotes. | |
| Sea otters are a keystone species, which means they have a large impact on the ecosystem. Sea otters eat sea urchins so the urchins won’t overpopulate and kill off kelp forests by eating them—Keep them in check. | |
| Lionfish are invasive species, which spread from aquarium trade. Invasive species are species that have no predators and a lot of resources while actively destroying the ecosystem | |
| Coyotes | highly adaptable omnivores thriving in cities by using green spaces (parks, golf courses) for shelter and hunting rodents, rabbits, and even deer, while also scavenging human |
| Rabbits | they are "ecosystem engineers," influencing vegetation and nutrient cycling through grazing and defecation, while facing high mortality from predators, disease (like tularemia), and habitat loss. They are also invasive species. |
| Penguins | acting as vital links in Southern Hemisphere food webs, transferring ocean nutrients to land via droppings, and serving as prey for seals and orcas while eating fish, krill, and squid they are critically sensitive to climate change, with melting sea ice a |
