Rough Endoplasmic Reticulum: series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
Smooth Endoplasmic Reticulum: comprises of a tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is reticular in appearance. The network of smooth endoplasmic reticulum allows for an increased surface area to be devoted to storage of key enzymes.
Black the creamer makes it look white along with the side of the cup that it is in and the lighting and your phones picture could also make it different than it looks
C. The process by which green plants and some other organisms use sunlight to synthesis food from carbon dioxide and water.
Answer: A branched polymer has greater terminal glucose residues in comparison to a unbranched polymer of the same molecular weight resulting in a higher number of terminal glucose residues required to be mobilized when energy is demanded. Enzyme and polymer evolve together to meet the dire need for rapid mobilization.
Explanation:
In comparison to an unbranched polymer, a branched polymer has a more compact and symmetrical molecular conformation with a greater terminal glucose residue. It can be broken down easily when energy is needed. For instance, the branched form of starch, amylopetin, in the small intestine starch is hydrolyzed to form glucose which is converted to biochemical energy and stored for later use.
Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle and Theophrastus tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.
Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.
So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.
Goal of modern classification system:
Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.
Thus modern goal is better in many terms and is more reliable than old classification goals.
Hope it helps!
