Answer:
When the level of calcium ions declines the sarcoplasm stops the sliding.
Explanation:
Sarcoplasm can be described as the cytoplasm for the cells of muscles. It contains important structures such as the myofibrils.
The following steps would occur when the level of calcium ions would decline:
The sarcoplasm would stop the sliding of the thin filaments.
The actin filaments would be migrated in the M line
This would lead the bands in the I region to shorten.
The Z region would compress.
The H region would diminish.
Answer:
The correct match would be:
- Swallow - migration
- Tiger - sparse distribution—scarce
- Devil’s Hole pupfish - local endemic
- Humpback whale - sparse distribution—widely dispersed
Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.
Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.
Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge in Nevada city of the United States
The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.
The edge of two crustal plates that shift are known as plates that transform.
Over 90% of all parasympathetic fibers are derived from the cranial nerve X, which is the vagus nerve.
The vagus nerve influences most organs below the neck. The activation of this nerve affects heart rate, blood pressure, production of stomach acid, movement of food through the intestines and breathing.
