simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic cells are more complex than prokaryotes; the major difference between the eukaryotic and prokaryotic cells is the nucleus. The nucleus in a eukaryotic cell is

‘How could natural selection increase the number of children born with sickle-cell disease in certain regions when these individuals are unlikely to survive and produce offspring?’ Darwin’s theory proposes that 3 conditions are a requisite for natural selection to occur. They are a struggle for existence of the offspring as they are competing for limited resources‚ variation within species which gives some individuals advantage over others hence better chance of survival and lastly inheritance
