Question
Nematodes and annelids are both commonly referred to as 'worms'. How could you quickly tell whether an organism nematode or an annelid? Compare the feeding mechanisms of the classes of Mollusca. The class Insecta within the Arthropoda phylum is hugely diverse. What may have caused this huge burst of diver group? Arthropod body types vary in the number of segments. Which groups that we looked at last week have the most Which have the least? Which phylum or class from last week do you consider to be the most interesting and why? Cite specific ecological traits that you learned from last week, not from common knowledge.Explanation / Answer
3)Answer:
To find out whether an organism is annelid or nematode the difference is that aneelid will be having the segmented bodies having segment on them whereas the nematode will not be having the segmented body. so with this we can distinguish among them.
4) Answer:
The mollusca is from the phylum group and are known as the invertebrate animals there are about 8 classes in the phylum mollusca group out of which one is extent now and only seven are present. so the mollusca usually use the tongue like structure called radula when there is the need of feeding.
Class Bivalvia: so the organism in this class can carry out the mechanism of the feeding using their gills. they also use them for respiration and also for the filtering feedind.
Whereas class scapnopoda use their tentacles to carry out the mechanism of feeding.
5) Answer:Class insecta of the anthropoda phylum is hugely diverse because the insects in this class has the characteistics that they cannot able to regulate their body temperature and thats why they can surviev in every environment whether it is hot or cold environment and thats why they are hugely diverse.
