Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.

Which observation provides evidence that a cell is most like/ya prokaryote?
Over [174]

Answer:

C. It has DNA that is not contained within a nucleus.  

Explanation:

If we look at golgi apparatus, they are one of the most prominent characteristic of a eukaryotic cell because they are membrane bounded organelles. As we know that in prokaryotic cells there are no membrane bounded organelles so option A is incorrect.

If we talk about long tail like structure, then it can be correct option because many prokaryotic organisms like bacteria have flagella for movement. However, there is Euglena which has flagella but it is a eukaryote. It means that option B can be false.

If we look at option C, it says that DNA of the cell should not be necessarily in nucleus. This looks suited for prokaryotes like bacteria because they donot have any nucleus and DNA is positioned almost center of the cell without any nucleus. So option C is best option.

If we look at option D, again it cannot be right answer because they are one of the most prominent characteristic of a eukaryotic cell that their organelles are large and covered with membranes.

Hope it helps!

In which of the female's reproductive structures would embryonic or fetal pigs be found
MariettaO [177]
The pig embryo or fetus are both developmental stages in a pig's life cycle from conception and leading up to birth. The embryo and the fetus should be found in the uterus lining of the female pig, as this is where conception would occur and where the fetus will develop until it is ready to be born.
