All but one of the following statements are true regarding the differences between early and late spermatids. select the answer below that does not reflect a difference between early and late spermatids.
a) early spermatids are round and have excessive cytoplasm.
b) early spermatids have not undergone meiosis and are still diploid.
c) early spermatids have not undergone spermiogenesis.
d) early spermatids have not formed a flagella.

B) Early spermatids have not undergone meiosis and are still diploid.

Explanation:

Spermatids are formed at the end of meiosis in the testes of male. Spermatids are haloid cells in which chromosome numbers are half as compared to their parent cells. An early spermatid has not undergone morphologic changes and is considered less mature than the late spermatid.

Late spermatids undergo morphological changes (spermiogenesis) and they transform into a spermatozoa which is ready to release in the lumen.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
