An alimentary canal is a digestive tract that is complete and has two openings which are the mouth and the anus. On the other hand a gastrovascular is a digestive tract that has only one opening.

The kingdom Protista includes large diversity of organisms ranging from flagellated cells to macroscopic organisms. It is sometime referred as Protoctista instead of Protista. Some of the ancient Protista’s have characteristics of animal and plant kingdom. For example Lichen is not a protist but it includes the characteristics of both Protista and Fungi. Likewise organisms such as algae, bacteria, ciliates have the features of Protist as all these are Eukaryotic cells. Since the formation of kingdom Protista many animals have been included and excluded from the kingdom. Even today red and brown algae are considered as protist
Answer:
d. the movement of myosin head while attached to actin myofilament
Explanation:
During muscle contraction, the calcium ions released from the sarcoplasmic reticulum in the sarcoplasm bind to troponin which in turn removes tropomyosin from the myosin-binding sites present on the actin. Hydrolysis of ATP at the myosin heads energize them. These myosin heads with stored energy bind to the myosin-binding sites on the actin filaments. In their bound conditions on the actin filaments, myosin heads are called cross bridges. Only one myosin head of a single myosin molecule forms cross-bridge at a time.
