The agent of erosion, which carried sediments that scratched bedrock is A MOVING GLACIER.
Agents of erosion refers to those forces that cause erosion. There are basically four agents of erosion, these are wind, running water, glaciers and gravity.
Glaciers are large sheet or block of ice that move along a landscape. Glaciers are powerful agents of erosion; moving glaciers are capable of removing loose rocks on their way of movement. They can also pick up and move particles of varying size. Moving glaciers usually carry sediments which scratch and polish bedrocks surfaces.

Explanation:
Explanation:
Some of the mice will be homozygous dominant (AA), others will be heterozygous (Aa) and others homozygous recessive (aa).
Because the population isn't homogeneous, the easiest way would be to mate all grey mice on one side, and all yellow mice on the other, and analyze the phenotype of the offspring.
The cross between mice with the recessive trait will have <u>100%</u> offpsring with the recessive trait.
However, the cross between mice with the dominant trait will show some recessive individuals in the offspring:
- AA x AA ---> all A_
- AA x Aa ---> all A_
- Aa x Aa ---> 3/4 A_, 1/4 aa
The answer is intercalated discs. They allow the heart muscle cells to function as one organ due to a phenomenon known as syncytium. This is where uninuclear cells fuse to form an apparent multinucleate cell. This way the heart muscle cells can contract in synch. Intercalated discs appear in the sarcomere's (of the muscle fibres) Z line.
