packed, processed in golgi apparatus and exported in vesicles via exocytosis</span>
<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>
The scientist should compare the anatomies of the fossil and present day dragon fly to determine the relation between the two.
Explanation:
- Diet is a common factor between many species,i.e. Different animals can have same died for example there are several grass eating species so this will not establish a close relation between the two.
- A single habitat can be occupied by different species , for example a grassland can be the habitat of lion, zebra , various insects etc. Secondly, getting a clear idea about the habitat of a fossil specimen is difficult and can be hypothetical. Thus, this is not a criteria to be compared.
- Different animal can have same predator, for example, a zebra, a deer and a nil gai have lion as the predator. Again determine the predator of a fossil specimen is very difficult and might lead to a hypothetical conclusion. Thus predators are also not factors of comparison here.
- The Anatomy of an organism is quite similar to its ancestor, the structural plan of the body can easily be compared. For example the anatomical features of man and apes are closely established. Thus, Comparing the anatomy will determine the closeness of the give species.
