In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation
Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.  

These fibers have the  ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

Answer:

The artificial reef would decrease erosion of the coastline.

Explanation:

Artificial reefs are created in area where there is little uderwater topography or near established coral reefs to imitate or even substitute for natural coral reefs where they are absent or endangered due various factors which are mostly human in nature. The artificial serves to provide a habitat for marine organisms and ensure more biodiversity around the area by providing shelter from predation and surfaces for encrusting organisms such as corals and sponges to grow on. The growth of these lower level food chain organisms attract larger predator organisms thereby increasing the biodiversity in the area.

Artificial reefs are made from a variety of materials such as shipwrecks, construction debris, oil rigs, concrete, and any other man-made objects. Since reef structures protect shorelines against waves, artificial reefs would decrease the erosion of the coastline providing benefit to the people living along the coastline by preventing the destruction of beaches and coastal property,
