An organism has long cylindrical thread-like body. Its body wall has longitudinal muscles but no circular muscles. It is a pseudocoelomate. Identify the phylum to which it belongs.

During a field visit, one of the students observed a cyclindrical worm in the soil, and noted its characteristics like segmented body, bilateral symmetry and presence of clitellum. After its dissection , students observed that the worm was eucoelomate . Another student observed a worm which was thread-like without segments and after its dissection they found that the worm was pseudocoelomate. Baed on the given paragraph answer the following questions. Mention any two characteristics of the thread-like worm , observed by the second student.

Identify my class/phylum and give one example of it. I live in your small intestine, my body is long and thread like and pseudocoelomate.

Identify me. I live in your small intestine. Pseudocoelom is present in my thread like body. In which phylum will you include me?

Identify me: I live in your small intestine. Pseudocoelom is present in my thread like body. In whcich phylum will you include me?

A body moving along a circular path of radius r with velocity V, has centripetal acceleration 'a'. If its velocity is made equal to 2V, then its centripetal acceleration is.

Our body contains a large number of Cells "L" which are the longest cells in the body. L has long and short branch called as 'M' and 'N' respectively there is a gap 'O' between two 'L' cells, through which nerve impulse transfer by release of chemical substance e 'P' : What are M and N?
