Cells & Genetics
This flexible outer barrier acts like a cellular security guard, controlling exactly what goes in and out of the cell.
What is the cell membrane?
Liquid hot rock is called magma when it is trapped deep underground, but it changes to this name the exact second it erupts onto Earth's surface.
What is lava?
Unlike stored potential energy, any object that is actively in motion possesses this type of energy.
What is kinetic energy?
In an ecosystem, non-living components like sunlight, rocks, temperature, and water are classified by this scientific term.
What are abiotic factors?
Water is one of the only unique substances on Earth that naturally exists across all three of these standard states of matter at the same time.
What are solid, liquid, and gas?
In the levels of biological organization, this 6-letter word describes a large group of similar cells working together to perform a specific job, like muscle or nerve.
What is tissue?
While Earth's orbit around the sun causes our yearly calendar, Earth spinning on its own axis every 24 hours causes this daily cycle.
What is day and night/rotation?
While your weight will drastically change if you travel to the Moon, this measurement of the actual amount of matter inside your body stays exactly the same.
What is mass?
Humans, grizzly bears, and seagulls belong to this category of consumers because their diets regularly consist of both plants and meat.
What are omnivores?
Despite having an incredibly long neck, a wild giraffe has this exact same number of neck vertebrae bones as a human being.
What is 7?
This organelle acts as the cell's storage warehouse, holding onto water, waste, and food. It is massive in plant cells but tiny in animal cells.
What is a vacuole?
This specific type of rock forms over millions of years when layers of sand, mud, and ancient seashells are squished and glued together.
What is sedimentary rock?
When hot water vapor hits the cold glass surface of a soda can and instantly turns back into liquid water droplets, it undergoes this phase change.
What is condensation?
A bee gathering pollen from a flower is an example of this specific type of symbiosis, where both organisms walk away benefiting from the interaction.
What is mutualism?
You will always see a flash of lightning during a storm before you hear the physical boom of thunder because this travels significantly faster than sound waves.
What is light?
This major body system includes your heart, veins, and arteries, and is responsible for pumping oxygenated blood to your limbs.
What is the circulatory system/cardiovascular system?
The heavy rise and fall of Earth's ocean tides are primarily caused by the gravitational pull of this celestial neighbor.
What is the Moon?
On the Periodic Table of Elements, columns are called groups, but these horizontal rows signify elements that share the same number of electron shells.
What are periods?
Food shortages, lack of clean water, and a surge in local predators are examples of these kinds of environmental factors, which actively stop a population from growing too large.
What are limiting factors?
While a fully grown adult human has 206 bones in their body, a newborn baby is actually born with roughly this many separate bones before they fuse together over time.
What is 300?
These tiny, dot-like structures are scattered throughout the cell's cytoplasm and have the incredibly important job of building proteins.
What are ribosomes?
Deep inside the Earth's mantle, hot rock slowly rises toward the crust while cooler rock sinks back down. This looping cycle of heat is called a what?
What is a convection current?
If an object has a total mass of 20 grams and a total volume of 10 cubic centimeters, this is its exact calculated density.
What is 2 grams per cubic centimeter?
This 5-letter word describes the highly specific role, habitat, and "job" an organism has within its community to avoid directly competing with other species.
What is a niche?
While humans and animals absolutely require oxygen to breathe, this gas actually makes up the single largest percentage (about 78%) of Earth's atmosphere.
What is nitrogen?
