Answer:
Carbs, lipids (fats), proteins, and nucleic acids.
There can be more than 2 chromosomes. for example, Down syndrome or trisomy 21 has 1 extra chromosome 21 causing down syndrome. in others, one chromosome could be taller or shorter than its pair by deletion or insertion. another way is having one of the chromosomes missing. in a specific disorder (don't remember which) a female has a missing X which means she only has one causing her to not develop breasts or the hip-widening most girls experience as they grow. sorry if this is not the answer you were looking for.
Evolution has led giraffes to have very long necks. Trees in the savannah have less leaves on bottom branches because of other animals. For the giraffe to survive, their necks slowly became longer as they could eat more leaves from upper/top branches. If they had not evolved longer necks, they would not exist today.
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.
