what is current electricity
the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit.
100
iron melting is a...
Physical change?
100
is eye color inherited or acquired?
it's acquired jk inherited
100
constructive, destructive or both,a volcano erupting?
It's both.
100
why cant we see microorganisms with our eyes?
because they are too small and the root micro means small
200
what does a battery do in a circuit?
it provides electricity and allows the current to flow
200
is baking a physical change
no because it cannot be undone (don't get tricked by this for latter questions)

what are sand dunes and how do they form
Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form.
200
what does the cell wall do in a plant cell?
it gives it structure protects the cell
300
How does static electricity work?
results from unbalanced charges that move abruptly from one place to another, rather than flowing in a current.
300
baking is a physical or chemical change
it's chemical
300
is hair color inherited or acquired?
its inherited but can be acquired by dying it
300
how do volcanoes form
when one tectonic plate moves under another.
300
what does the mitochondria do?
turns food into energy
400
Two light bulbs sharing the same battery is a
series circuit?
400
if you mix a blue and green liquid and get yellow liquid and it cant be undone is this a physical or chemical change
it's physical because mixing is always physical unless a solid or gas is formed from two liquids making it a chemical reaction

inherited or acquired ? height
inherited

What are the 5 main parts of an animal cell
- Cytoplasm (the region between the cell membrane & the nucleus) ...
- Endoplasmic Reticulum (passageways carry protein & other materials from 1 part of a cell to another) ...
- Nucleus (control center of the cell) ...
- Mitochondria (turns food into energy the cell can use) ...
- Cell Membrane (controls what comes into & out of a cell)
500
if a circuit has a battery light bulb and a gap with two metal balls on the tip of each gap what would happen, and would it be considered as static,current or both electricites?
there will be both static and current electricity causing the circuit to flow.
500
if a magnet was melted and frozen would it keep its magnetism and is this a chemical or physical change
this is physical and the magnet keep its magnetism
500
is your language you speak and think in inherited or acquired
it's acquired because you speak and think the same language of the people around you overtime

how is a delta formed
Where the river enters the water body, the water's flow decelerates, sediments drop out, and a delta forms, depositing a prism of sediment that tapers out toward the lake's interior.

what does the nucleus do in an animal cell
sends orders to the rest of the cell
