There are two main sources of ocean sediment:
<span>1.External (terrigenous) formed from the deposit of insoluble materials, like <span>rock and soil particles. It is transported from land areas to the </span>ocean by wind, ice, and rivers. It also includes products of submarine volcanism.</span>
<span>
2. Internal (biogenic and authigenic) formed from the remains of marine organisms or their shells and from chemical precipitates from the seawater.</span>
Make connections: How might having the anther atop a tall filament make it more likely that plants will be pollinated? It gets the pollen grains up higher. That makes it more likely that a visiting insect will pick them up.4. ... When the pollen forms on the stamen, the pistils are not ready to receive it.

proteins
</span>Proteins are biological macromolecule and mostly composed of enzymes. In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins. </span><span>Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. <span>
