Choose all the answers that apply. Erosion is caused by _____. wind water ice gravity
bezimeni [28]
Water erosion is usually what people think of, but ice, wind and gravity can also cause erosion.

Water erosion is usually along rivers. As the water moves quickly by it rubs on the rock and dirt, causing rivers to slowly get wider.

Ice erosion is caused by glaciers. Sometimes it's a glacier rubbing against land, and there's a lake that was made by a glacier making it's way onto land and then melting.

Wind erosion is a big problem in fields and large open plains with loose dirt. The wind just blows all the dirt away.

Gravity can cause erosion and cliffs. Sometimes along a mountain or cliff the rock won't be able to hold itself up anymore, and gravity will pull it down.

Your answer would be all of them. Wind, water, ice, and gravity.

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re
NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

Disclaimer: your question is incomplete, please see below for complete question

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above
