The independent variable is the temp because that’s the only thing that changes
dependent is everything else because it doesn’t change
no they aren’t comparing it to any thing, just each other. the control should remain the same throughout the experiment but there isn’t any in this case
light and water because they same through out the experiment
good luck :)
Definition: the principles that govern heredity were discovered by a monk named Gregory Mendel in the 1860,s on of these principles, now called Mendel law of segregation states that all pairs separate or segregate during gamete formation and randomly unite at fertilization <span />
We need to breath every day and hat just happens to be the amount of times we breath, but a human can actually breath up to 30,000 times per day it all depends.
A) They trap the suns heat to warm up the earth, like a real greenhouse
Answer:
B
Explanation:
For metals, the further away the valence electrons are from the nucleus, the higher the reactivity of the elements. Unlike halogens that are more reactive if the valence orbital shells are closer to the nucleus. This is due to ionization energies – which is the minimum energy required to discharge an electron from its orbit.
For metals this should be lower because they need to lose electrons to attain a stable electron configuration. For halogens it should be high because they don't need to lose electrons, but rather gain, in order to attain stable electron configuration.
Electrons in their orbital shells need to occur in pairs (with opposite quantum states) to be in stable configuration and as long as an atom has orbitals with single electrons, the atoms will be reactive as opposed to when its orbitals are ‘full’.
