<span>The correct answer is paleomagnetism. This is mostly done, however, in regards to the magnetic properties found in the earth itself, like in rocks and minerals or ores, and less with the actual magnetic poles of the earth, but it does encompas it too. It is very useful in the science of tectonic movements and discovering the chonology of geology.</span>

Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.
