Explanation:
During spermatogenesis, some diploid spermatogonia become larger in size and transform into primary spermatocytes. These diploid primary spermatocytes enter meiosis to produce haploid spermatids. One primary spermatocyte enters meiosis-I and produces two secondary spermatocytes. These secondary spermatocytes are haploids. Each of these two secondary spermatocytes enters the meiosis-II and produces two haploid spermatids. In this way, one diploid primary spermatocyte produces four haploid spermatids.
Answer:
Fossils can be described as the dead remains of plants and animals which are used to study evolutionary histories of organisms. The most common type of rocks on which imprints of dead plants and animals will form are the sedimentary rocks. The fossils found on the sedimentary rocks can also be used to date the sedimentary rocks and study how old the rock or the imprints on it are.
Answer:
secondary succession happens more often because it occurs after some kind of distribution that still leaves the soil intact (mudslide,bulldozing,shoveling,or scraping off an area)
