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!
Answer:
b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Explanation:
Hello,
In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.

Thunder is caused by the extremely rapid expansion of air around a bolt of lightning due to the very high temperature. It is also caused by the change of pressure around a lightning bolt.
