Locations at latitude closer to the equator receive stronger and more direct sunlight than locations near the poles.
Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

A Scientist.
Topography is a field of geoscience and planetary science and studies the forms and features of land surfaces. Topography maps are extremely useful to scientists to show geographic features above and below sea level, including the geology of a region
