When mammalian spermatozoa exit the testis, they show a highly specialized morphology; however, they are not yet able to carry out their task: to fertilize an oocyte. This property, that includes the acquisition of motility and the ability to recognize and to fuse with the oocyte investments, is gained only after a transit through the epididymis during which the spermatozoa from the testis travel to the vas deferens.

Environmental Problems Of Industrialization And Sustainable Development In Nigeria - A Review, Adejoh Iyaji

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

The main objective of this paper is to examine the impact of the quest for industrialization on the environment in Nigeria; others include, the identification of the objectives of sustainable development as well as making recommendations that will lead to the much needed sustainable environment both for the present generation and generations yet unborn. The researcher relied principally on secondary sources of data for this paper which is theoretical in approach. Findings revealed the emergence of a host of environmental problems such as air pollution, deforestation, desertification, solid and hazardous waste problems in the wake of the quest for industrialization. …
