What is being moved in both mitosis and meiosis? why do we have to have mitosis and meiosis?

1. The right answer is chromosomes.

The purpose of cell division (mitosis or meiosis) is to obtain identical or non-identical cells with genetic material. That is why during the division there is a reworking of the chromosomes (carrier of the genetic information) which will distribute the chromosomes equitably on the two daughter cells. if the distribution is not equitable, it leads to genetic diseases such as trisomy 21.

2. Importance of mitosis and meiosis:

Mitosis is a crucial step in the cancer process. Mitosis is the cell division that allows an equal distribution of genetic information from an initial mother cell to two daughter cells while retaining the karyotype over the cell generations.

Meiosis is a cell division that, alternately with fertilization, plays a key role in sexual reproduction, reducing the number of chromosomes in gametes by half, thereby preserving the number of chromosomes of the species after fertilization.

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.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
