Answer: why it is hard to use dichotomous key in the lab are;
If the organisms you want to use it for are similar.
If you can't see the little characteristics posses by the organisms you are using it for.
If all the pictures does not reveal all the important features of the organisms.
It is very difficult to use it to determine the anatomical structure.

prokaryotic cells do not have a nucleus or membrane bound organelles.They also have small rings of double-stranded extra-chromosomal DNA called plasmids.
<u>The four types of interactions in communities are:</u>
- Mutualism
- Parasitism
- Commensalism
- Competition
<u>Definition of each interaction:</u>
<em>Mutualism: </em>
The type of interaction in which both the species involved are benefited, it is called mutualism.
<em>Parasitism:</em>
The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.
<em>Commensalism:</em>
The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.
<em>Competition:</em>
The type of interaction in which both species lose is called competition. It is opposite of mutualism.
<u>Symbiotic relationship:</u>
It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.
