Question

One animal that does not perform locomotion is
A. sycon
B. nereis
C. sepia
D. euglena
E. none of the above

Answer 1

Hint: Animal locomotion, in ethology, actually is any diffusion of techniques that animals use to move from one place to a few different, or in order that they essentially the concept in a subtle manner. a few modes of locomotion are self-propelled, examples are running, swimming, jumping, flying, hopping, hovering, and gliding, form of contrary to popular notion.

Complete answer:
Sycon typically is a small marine sponge subtly. It is in reality discovered in without a doubt shallow water up to an intensity of 90 m, wherein the sponges essentially get plenty of food and nicely oxygenated water, which is pretty widespread. One gives up essentially is connected to the substratum, while the pretty loose give up without a doubt bears a specially large beginning known as osculum fringe, demonstrating how it's far sincerely located in a sort of shallow water up to a depth of ninety m, in which the sponges essentially get masses of food and nicely oxygenated water in a diffused way. This osculum fringe checks small fairly animals from stepping into the frame, demonstrating the way it mainly is for the maximum component determined in shallow water up to an intensity of 90 m, where the sponges get masses of food and properly oxygenated water in the main way. The body floor particularly bears minute pores known as Ostia, without a doubt similarly displaying the way it, in particular, is hooked up to a few submerged rocks, which specifically within reason are great. The Ostia generally opens right into a commonly large honestly relevant cavity known as spongocoel or perigastric cavity via a machine of canals, demonstrating how this osculum fringe, so sycon is a small marine sponge, which typically within reason big.

Hence, the correct answer is option (A).

Note: Microspores sort of are produced by using meiosis interior anthers and megaspores in the main are produced interior ovules that for the most component are within an ovary, especially similarly displaying how microspores for all intents and functions are produced employing meiosis inner anthers and megaspores are produced inside ovules that in particular subtly are within an ovary.
