The Linnaean system of classification is still used because it provides an internationally recognized method for organizing and identifying species. Changes to the Linnaean system, like the addition of more kingdoms and the domain division, represent advances in scientific knowledge. Despite the modifications, the fundamental purpose of classifying biological diversity remains intact, making the system robust and adaptable.
We continue to use the Linnaean system of classification because it provides an internationally accepted method of organizing the vast diversity of life on Earth. Just like a library uses a classification system to organize books, taxonomy helps to organize and identify the millions of species on Earth. Changes to the classification system over time, such as the addition of more kingdoms and the higher division of domains, reflect advances in our scientific understanding, especially in the realm of genetics and molecular biology.
Carl Linnaeus initially categorized life into two kingdoms: the plant and animal kingdom. But with the expansion of scientific knowledge, three more kingdoms have been added to include fungi, protists, and monera (bacteria), and three domains were introduced: Bacteria, Archaea, and Eukarya.
These changes to the Linnaean system reflect the presence of more complex relationships among organisms than initially understood. The system remains robust and useful by accommodating changes based on new scientific discoveries and technological advancements. Its hierarchical nature allows it to be flexible and adaptable to incorporate new knowledge while maintaining its foundational purpose of classification. Hence, despite modifications made to this classification system since its inception, it continues to be the fundamental framework for typing biological diversity.

What if the blood flow of the antrial systole?
b. euglena
c. diatoms
d. spyrogyra
from the choices listed above is option D.
Starch, cellulose, and glycogen are polysaccharides composed of glucose. Starch and glycogen, both used for energy storage, are branched polymers with α-1,4 and α-1,6 glycosidic linkages while cellulose, used for structural support, forms a linear structure with rigid β-1,4 glycosidic linkages.
Starch, cellulose, and glycogen are all polysaccharides composed of glucose units. Starch is a branched polymer which is the primary form of energy storage in plants. It has α-1,4 and α-1,6 glycosidic linkages without the tight crosslinks of cellulose, hence it is less rigid than cellulose.
Cellulose is a linear chain of glucose molecules and forms rigid β-1,4 glycosidic linkages, serving as a structural component in the cell walls of plants and other organisms. Due to its arrangement, it is rigid and forms the structural fiber in plant-based foods.
Glycogen is also a branched polymer, and is the principal storage form of glucose in animal cells and bacteria. While the glycosidic linkages in starch and cellulose differ, glycogen, similar to starch, has α-1,4 and α-1,6 linkages. These different molecular structures allow carbohydrates to serve varied functions such as energy storage (starch and glycogen) and providing structural support (cellulose).
