Answer:

Ca+ binds to troponin

Troponin removes tropomyosin from G actin

Myosin binds to actin

Myosin generates a power stroke

The sarcomere shortens

ATP recharges the myosin head

Explanation:

Contraction begins with the release of calcium ions into sarcoplasm where they bind to troponin. It moves the tropomyosin always from the myosin-binding sites present on actin. Myosin head binds to actin and forms cross-bridge followed by power stroke in which myosin head pivots to pull the thin filament past the thick filament towards the center of the sarcomere and results in shortening of the sarcomere. The myosin head binds to ATP and the cross-bridge detaches from actin. Hydrolysis of ATP charges myosin head again.

MrMuchimi

the correct answer is A- Reproductive isolation occurred through behavioral isolation

A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.

In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
