Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers.

Every cell in the body of living organisms requires oxygen for its survival. Hemoglobin is a type of blood cell which is responsible for the transportation of oxygen and carbondioxide in the body.

Explanation:
Answer: Option A.
Transverse tubules rapidly move the action potential to the interior of the muscle potential.
Explanation:
Transverse tubules are cylindrical pockets found in the plasma membrane of muscle cells. They are formed from phospholipid bilayer or sarcolemma of skeletal or cardiac muscle cells. They have membrane that have large concentration of ion channels,transporters and pump. They permit action potention into the cell and also to a particular structure sarcuplasmic reticulum. They play a role in regulating cellular calcium concentration.
