Answer:
Aboitic factor would be soil
Biotic factor would be ants.
Explanation:
Atomic mass is the sum of all isotopes' abundace-mass product. First start by finding the abundance of isotope B (isoB% = 100- isoA% - isoC%). Now plug in all known values into (mass = Amass*A% + Bmass*B% + Cmass*C%) and solve for Bmass
Answer:
False
Explanation:
Forms of a given element that have a different number of neutrons are called isotopes.
In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial.
