Delve into fascinating discoveries, evolutionary marvels, and the intricate workings of living organisms. From cells to ecosystems, explore the wonders of the natural world and how biology shapes our understanding of life itself.
Conservation strategies are often directed to individual species or for habitats identified as species-rich and therefore tend to assume that most individuals of a particular species have been assigned correctly. Many biologists argue that identifying species is far from straightforward. The biological species concept (BSC), defines species as “…groups of actual or potential interbreeding natural …
A recently established taxonomy approach attempts to identify species solely on the basis of a genetic barcode (also called a DNA barcode) consisting of one or a few DNA sequences. For example, a 648 bp region of the mitochondrial cytochrome c oxidase I (COI) gene continues to be developed as a barcode identifier in animals. …
There are different levels of organization in living systems, from molecules like DNA (genes) to the entire biosphere. When it comes to biology levels of organization they start from: genes → cell → organ → organism → species population → community → ecosystem → biome → biosphere Living beings are extremely organized and structured, following …
Sometimes science seems like something that takes place in a laboratory away from everyday life. It may be, but the impact of ‘s scientific research is having a tremendous impact on your daily life, from the food you eat the energy that powers your home. Here are some of the ways that biology affects your …
What Is A Cell Biology? Cell biology is the examination of cellular structure and function and revolves around the concept that the cell is the basic unit of life. In the 1830s, two scientists, Schleiden, who studied plant cells and Schwann, who first studied animal cells, provided, the first clearly established definition of cell is …
Not all scientists agree on what life is all about. There are several features that describe most living things. However, for most of the features listed below, we can think of one or more examples that might break the rule by classifying something that doesn’t live as alive or something that lives as non-living. Hence, …
In addition to the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall that surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress, and also allows cells to develop turgor pressure, which is the pressure of the …
