Thermal Energy
A classic example is boiling water on a stove, where hot water rises and cooler water sinks is an example of what type of transfer?
convection
All LIVING things are made of these...
cells
This system is the body's command center, responsible for coordinating actions and sensory information by transmitting/sending signals to the body. (brain, spinal cord, and ________)
Nervous System
_______=nerves
The _____ powers the water cycle by providing the energy necessary for evaporation and condensation, which are key processes in the cycle.
sun
The measure of the average kinetic energy of the molecules in the air.
temperature
What materials are good conductors of heat?
Metals: silver, copper, gold, aluminum, and iron
a jelly-like substance that fills the cell and holds organelles in place
cytoplasm
Organs working together to facilitate the exchange of oxygen and carbon dioxide, enabling the body to breathe describes what system?
Respiratory
Clouds form in the water cycle through a process called ___________, where invisible water vapor in the air cools and changes into tiny liquid water droplets or ice crystals.
condensation
Maritime air masses are typically _____ than continental air masses.
more humid
The heat from the sun reaching Earth or the warmth from a fire is an example of what type of heat transfer?
radiation
Surrounds the cell and controls what goes in and out
cell membrane
What two body systems are working together to ensure that oxygen is delivered to the body's tissues and carbon dioxide is removed?
Respiratory and Circulatory
The sun's heat causes water on the ocean's surface to _____________, turning into water vapor (gas).
evaporate
air mass
Why does warm air or liquid rise while cool air or liquid sinks?
Warm air/liquid is LESS DENSE
Cool air/liquid is MORE DENSE
What provides rigidity and prevents the plant from collapsing under its own weight or external pressure, allowing plants to stand upright? (Hint: Only found in plant cells)
Cell Wall
The process where the body senses changes in its internal environment and initiates responses to restore balance
homeostasis
Water droplets in the clouds get too heavy to stay suspended and fall back to Earth as rain, sleet, snow, or hail. This is called...
precipitation
a violent, rotating column of air that extends from a thunderstorm to the ground----forms when warm, moist air meets cool, dry air, creating instability in the atmosphere.
tornado
Why does a metal spoon feel colder than a wooden spoon at room temperature?
Thermal conductivity is a material's ability to transfer heat. Metals, like steel, are very good conductors, meaning they readily allow heat to flow through them. Wood, conversely, is a poor conductor, meaning it resists heat flow.
organelles where photosynthesis takes place
hint: only found in plants
chloroplasts
The three systems that mainly deal with human movement are
nervous, muscular, skeletal
Plants release water from their leaves into the atmosphere—a process called__________________.
transpiration
How does a continental polar air mass differ from a maritime tropical air mass?
A continental polar (cP) air mass is cold and dry, originating over land, while a maritime tropical (mT) air mass is warm and moist, forming over water.
