Outside of an atom Invertebrate -Have no backbone -Multicellular -No cell walls -Can't make their own food (heterotrophic) An earthworm would be an example of an... Invertebrate Vertebrae Have spinal cords and brains What kind of bones do birds have? Hollow bones Where is the Ring of Fire located? The Pacific Ocean Communicable Diseases Spread from one person to another Malaria, Influenza, TB, Polio, HIV/AIDS, and Hepatitis are all examples of ...... Diseases Communicable Diseases Inner Planets -Small size -solid surfaces and thin/no atmospheres -greater densities -varied atmospheres -spin slowly -orbit the sun quickly -few moons -no rings Outer Planets Huge size balls of gas with no surface smaller density similar atmospheres spin quickly orbit the sun slowly lots of moons have rings What were the first creatures to appear on Earth? Amphibians Vinegar is.... (acidic or basic) acidic What kinds of waves result from an earthquake? Seismic waves What kind of organism is made from sexual reproduction? A genetically unique organism What kind of organism is made from asexual reproduction? A genetically identical organism What does DNA stand for? Deoxyribonucleic acid What does the Mohs scale test for? Hardness Formula to calculate mass Density x Volume Formula to calculate density Mass/Volume Formula to calculate volume Mass/Density Formula to calculate weight Mass x Gravity Physical Weathering A process that breaks rocks apart without changing their chemical composition Examples of events that can cause physical weathering Swiftly moving water, ice wedging, plant root growth Chemical Weathering Decomposition of rocks due to chemical reactions occurring between the minerals in rocks and the environment Events that can cause chemical weathering Water, acids, oxidation Endocrine System Collection of glands that produce hormones that regulate metabolism, growth development, tissue function, sexual function, reproduction, sleep and mood How many light years are in 15 years? 15 Where is bile stored? The gallbladder What do the villi in the small intestine do? Increasing the surface area the small intestine has for absorption What do you use to treat Lyme Disease? Antibiotics Which planet has the shortest year? Mercury What is a comet? An icy, small solar system body that heats up when it passes close to the Sun, causing the production of gas and a visible atmosphere or coma and has a tail What would happen to the Earth if it had no moon? Tides would be much smaller, and the axil tild would vary tremendously over time What is the relationship between a frog and an insect? Predator-Prey What is an atom? The smallest unit of matter that retains all of the chemical properties of an element What is a grasshopper's role in the food chain? Consumer What is a dwarf planet? A planetary-mass object that is neither a planet nor a natural satellite -in direct orbit of the Sun, massive enough for its shape to be in hydrostatic equilibrium under its own gravity, not cleared the neighborhood around its orbit How do metal atoms become positively charged ions? When metal atoms lose electrons in their highest energy level Hot air moving fast evaporates more... commonly What happens to the molecules in something that is hot? The molecules are farther apart What happens to air when it is warmed? Molecules are farther apart so it takes up more room Which is lighter, hot or cold air? Why? Cold air has more molecules in the same amount of room as hot air, which makes cold air lighter and hot air lighter How many cells do all living things contain? One or more cells What helps break down fatty acids? Bile How many years is one revolution around the sun? 1 year What is heat conduction? Heat transfer of an object to the cooler part of the same object, transfer from a hotter object to a cooler object What is heat convection? Heat transfer by warm particles rising and cool particles fill in the space below, occurs in liquid and gases Sedimentary Rocks Formed by sediment that is deposited and compressed over long periods of time -made of minerals, pieces of plants Examples of sedimentary rocks limestone, sandstone, mudstone, chalk, clay stone What direction is latitude? horizontal What two things do you need to make an electromagnet? Iron nail and a battery longitude vertical
