Answer:
add 2 electrons
Explanation:
Add 2 electrons to carbide atom make it neutral because there are two unpaired electrons present in the carbide atom and it has -2 charge. So the carbide required two electrons for pairing and make the carbide atom neutral. for adding two electrons its all unpaired electrons paired to other two electrons which complete its valency and make it a stable atom.
False, atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes
Answer:
1.) The two gametes found in humans are the sperm and the ova.
2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
3.) Because the alleles that the mother and the father carry are mixed together in the offspring.
4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
