biological sciences
what is a mitochondria?
powerhouse of the cell = generate chemical energy
what is a divergent boundary?
Plates move apart from each other.
Magma rises to form new oceanic crust
Create mid-ocean ridges
Form continental rift valleys on land
what is kinetic energy
energy in motion
what is chemical energy called?
adenosine triphosphate aka ATP
what is a convergent boundary
Plates crash or push into each other.
Dense oceanic plates sink under lighter plates in subduction zones.
Form deep ocean trenches and volcanic island arcs.
Crumple continental crust to build huge mountains like the Himalayas
what is potential energy
stored energy based on position or state
plant vs animal cells
plant: cell wall, chloroplasts, large vacuole
animal: centrioles, lysosomes, small vacuole
what is a transform boundary
Plates slide sideways past each other.
Crust is not made or destroyed.
Friction builds stress that breaks rock to cause earthquakes.
Form visible cracks called strike-slip faults
examples of kinetic energy
include a rolling ball, flowing water, or wind
what is the cell membranes job?
controls what is coming in and out of the cell
what is a well known strip-like fault
the San Andreas fault
examples of potential energy
a rock at the top of a hill, a stretched rubber band, or food/batteries
relationship between cell structure, function, tissues & organs and how that promotes survival
Structure → function → survival:
Cells are specialised for specific jobs → tissues group similar cells → organs combine tissues to perform vital functions → organ systems work together to maintain life and enable survival.
how does seismic activity relate to tectonic plates
Seismic activity occurs when tectonic plates move, collide, or slide past each other, causing stress to build and release as earthquakes and vibrations
example of energy transfer
A bouncing ball: Gravitational potential energy turns into kinetic energy as the ball falls, then back into potential energy when it compresses and rebounds.
