living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things. Biology is a very broad field that encompasses the study of characteristics of living things. It includes

There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the functions of the body at the cellular level. Examples are digestion, the body's defense against disease, and transporting substances throughout the body. Thousands of proteins

Biodiversity in Lake Baikal We are in a world where there is a continuous exploitation of natural resources and very little care about the environmental consequences. Rapid industrialization has created havoc to the delicately balanced ecosystems. The effect that human population has had on global ecosystem is certainly undeniable and global biodiversity is being seriously challenged. The rapid deforestation of Amazon forest, the irreparable damage that we have done to the

Generics, Biologics, and Biosimilars Properties of Generic Drugs, Biologics, and Biosimilars, with Examples and Usage Generic drugs Generic drugs denote pharmaceutical products that are typically meant to be substituted with some innovator product manufactured with no license from innovator, and sold in the markets after exclusive rights (such as patents) expire (WHO, 2016). Some of the properties of these drugs include; Generic drugs are usually sold at prices considerably lower than branded price; and

This is indirect evidence of photosynthetic organisms." (Armstrong Chapter 2, pp. 6). Thus, photosynthetic organisms have been evidenced to have existed well into the Precambrian. Another source of data concerning life in the Precambrian comes from ancient stromatolites. Today, stromatolites can still be found in a handful of locations, and build upon each other by catching tiny particles of sediment. "Ancient stromatolites, dated to 3.5 gya, are constructed identically. Stromatolites,
