Answer:
Smooth muscle
Explanation:
- The smooth muscle is one of the three types of muscle present in the human body and other animals.
- The smooth muscle is called smooth because of its smooth appearance without any striations in its structure.
- The smooth muscle is made of the spindle-shaped cells characterized by a single nucleus.
- The smooth muscle cells are controlled by the autonomic nervous system and therefore is involuntary in its action.
The smooth muscle is present in the hollow organs and propels the substances through these hollow internal passages like in the alimentary canal of the digestive tract and urinary bladder.
Thus, the Smooth muscle is correct.

Symbiotic relationships in nature means that two organisms help each other. Coral reefs are poisonous to most sea life EXCEPT the clownfish, which uses the coral as homes. The clownfish also provide food for the coral, so both benefit.
Explanation:
Cellulose is a structural component of the plant cell wall. It is a polysaccharide consisting of a long linear chain of multiple β - 1, 4 linked glucose units.
Cellulose is difficult for most animals to digest except herbivores because they lack the ability or enzyme to digest cellulose. This enzyme needed is the cellulase which cleave to its β - 1,4 glycosidic bond and hydrolysis it into its constituent molecules (glucose).
Ans.
Gametophyte shows haploid, gamete-forming stage of plant's life cycle, while sporophyte shows diploid, spore-forming stage of plant's life cycle. In green algae, gametophytes and sporophytes are isomorphic (indistinguishable). In bryophytes, such as mosses, gametophyte shows dominant stage as it is most visible stage in their life-cycle. In vascular plants, such as ferns and seed plants, sporophytes show dominant stage.
Thus, 'seed plants show briefest gametophyte stage' and 'mosses show longest gametophyte stage.'
