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: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
Number 4 is not part of the cell theory
Living things cannot live without eachother due to the food chain, if an animal loses it's food so will his predator and so on. Soon they will end up extinct, this is why it's important to take care of animals.
