How has the coqui tree frog affected the population of native species
Inessa05 [86]

Answer:

The introduction of Coqui frog took place accidentally from Puerto Rico into Hawaii in the year 1988. The introduction of the frog species has posed a danger to the island ecosystem of Hawaii and is also a source of major noise nuisance. The species of the frog has an enormous urge to eating, which is putting the native species of spiders and insects of the island at a greater risk.  

The Coqui frog species can even thrive in distinct ecological zones and heights in the region and are also witnessed at the height of 4000 feet above the level of the sea. These frogs can also compete with the local fauna and the endemic birds, which are solely dependent on insects as the source of their food.

smooth muscle fibers can sustain a contraction without fatigue by allowing dephosphorylated myosin to remain attached to actin i
amid [387]

Smooth muscle fibers can sustain a contraction without fatigue by allowing dephosphorylated myosin to remain attached to actin in what is called the <u>Latch State</u>.

Latch State- Myosin cross-bridge creation with actin is prevented by dephosphorylating its RLCs, however dephosphorylating myosin that is already attached to actin slows down its off rate, creating the so-called "latch state." In the latch state, smooth muscle maintains tension while undergoing modest rates of ATP hydrolysis.

ATP hydrolysis- When the high-energy phosphoanhydride bonds in adenosine triphosphate are split, as occurs, for example, in muscles, chemical energy that has been stored in them is released. This process is known as ATP hydrolysis.

To know more about the Latch State, click on the below link,
