Identify the independent & dependent variables in the following experiment. Independent variable what the researcher changes, what we are testing
Dependent variable- what we are measuring what we are observing. This is what changes as a result of the independent variable changing
Experiment : What bird seed will attract more birds to my birdfeeder? I will try 3 different kinds of bird seed from the garden store in my bird feeder and count the number of
birds that come to the birdfeeder in a day,

the answer is true. hope it .

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
