7. When new rock is added to an oceanic ridge, the magnetized strips on either side
of the ridge are evidence of sea-floor spreading. This is because the rocks on the
two sides of the ridge
A are polar opposites
B are equal in width and in polarity
C are magnetized
D vary in width but are equal in polarity

ill try to . no promises tho.

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
