Prokaryotic cell don't undergo mitosis. If you observe a cell undergoing mitosis, then it is eukaryotic. In order for mitosis to occur, a nucleus must be present.
Moreover, Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus, meaning its DNA is surrounded by a membrane, and has other membrane-bound organelles. which allow the division of functions. The primary difference between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

If a student’s data did not support her hypothesis she should "<span>change the hypothesis" (after confirming that there weren't other variables that could have affected the result). It's important to be open minded when experimenting and not be too invested in your hypothesis when it proves to be wrong. </span>
Answer: t= -1.60
Explanation:
Let 
be the population mean weight of pigs.
As per given , we have
Sample size : n= 16
Sample mean =
Sample standard deviation : 
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean : 
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
It contracts on its own without input. The answer is C.
Hope that helped you.
