In human fertilization, two 1n haploid cellsâan ovum (female gamete) and a sperm cell (male gamete)âcombine to form a single 2n diploid cell called the zygote.NA is then replicated in the two separate pronuclei derived from the sperm and ovum, making the zygote's chromosome number temporarily 4n diploid. After approximately 30 hours, fusion of the pronuclei and subsequent mitotic division produce two 2n diploid daughter cells called blastomeres.
The Delta Force was secretly created in October 1977 by US Army Colonel Charles Beckwith in direct response to numerous, well-publicized terrorist incidents that occurred in the 1970s. From its beginnings, Delta Force was heavily influenced by the British Special Air Service.
The institution opened for its first regular session on September 15, 1925, with a faculty and staff of 11 members and an enrollment of 97 students. To match the institution's growth in enrollment and academic offerings, the name was changed to Delta State College in 1955 and to Delta State University in 1974.
