Terrestrial ecosystems (tetrapods)
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth.
Answer:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.

Answer: Monocytes.
Explanation:
Monocytes have a abundant amount of gray cytoplasm with fine lilac granules in it and because of this the cytoplasm appears ground glass.
The vacuoles are vacant and there is a gap sen in the cell as vacuoles when observed under microscope. The vacuoles of the monocytes are not stained.
They have a U-shaped nucleus and are extremely motile. The monocytes are lightly stained as compared to leukocytes.
