Explanation:
<em>The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.</em>
Proteins
Proteins are used for cellular repairing and chemical processes. Ribosomes are one of the most important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures enzymes such as proteins which will be utilized by many organelles in the cell. Microtubules are one, responsible for the framework and acts as a skeleton of the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of the cell. For a prokaryote or a eukaryote cell to survive, they need protein.<span> Fundamentally, the cell would cease to function and possibly die</span>
Answer: sediment deposited by the sediment flow of mass wasting are the slowest type of mass wasting
Mass wasting is the movement of large mass of rocks, boulders, slit, soil, sediments and ice down a slope. It occurs during retreating glaciers, landslides and mudflows. Moraine is a glacier deposit that develops during a retreating glacier. It develops when a glacier melts and it leaves sediments of ice, rocks and others over an area. As, the glacier ice may melt slowly, it is a product of slowest type of mass wasting.
Answer is D - DNA serves as a template to make a strand of mRNA.
