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.
The total magnification of a specimen viewed under a compound microscope is determined by the following:
Total magnification = (ocular lens magnification) X (objective lens magnification).
Neuroleptics are molecules that act on the nervous system by modulating both agitation and neuronal activity. These drugs have an effect countering the transmission of a neuromediator.
These side effects are numerous, among them there is tardive dyskinesia, including akathisia (a state of agitation, distress, and restlessness). This can be corrected by the administration of benzodiazepines such as lorazepam.
