Answer to Problem 2STP
Correct answer :
Option (D).
Explanation of Solution
Explanation/justification for the correct answer :
Option (D) Rotifera. The given diagram represents an animal with three region, head trunk and foot. It also has a group of cilia like structure that help in feeding and locomotion. Hence, the correct answer is option (D).
Explanation for incorrect answer :
Option (A) Annelida. The Annelida is a group of segmented worms. As the given animal does not represent the features of worm, it does not belong to Annelida. Hence, it is an incorrect answer.
Option (B) Nematoda. The Nematoda includes the round worms having a cylindrical body, as the animal in the picture does not have a cylindrical body, it is not a Nematoda. Hence, it is an incorrect answer.
Option (C) Platyhelminthes. The Platyhelminthes are flat worms and have small head with no cilia. Hence, it is an incorrect answer.

Your edited obligate apomict plants retains all the CRISPR "machinery" necessary to convert the "sexually reproducing" allele to the "obligate apomict" allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?
