The 10 Branches of Biology: Their Goals and Characteristics
The science that deals with living things is constantly evolving and specializing. Like any self-respecting science, biology spreads its efforts across various disciplines to cover as much knowledge as possible. This is necessary because there is more and more information. The various branches of biology make it possible to narrow down and focus knowledge inContinue reading “The 10 Branches of Biology: Their Goals and Characteristics”
Examples for Natural Selection
The process of natural selection refers to one of the mechanisms of the evolution of the species of living beings proposed by Charles Darwin and Alfred Russel Wallace, from which they explained the design of nature. For example: the white fur of arctic animals that allows them to hide in the snow. Natural selection occursContinue reading “Examples for Natural Selection”
Where Do the Pollen Grains of Flowering Plants Develop?
The place of production of the pollen grain differs according to the plant: In gymnosperms (seed-producing plants), the pollen grain is produced in strobiles. While in angiosperms (flowering plants), the pollen grain is produced in flowers, specifically in the anther (the part of the stamen where pollen is produced). The anther is a kind of tissue-covered pouch thatContinue reading “Where Do the Pollen Grains of Flowering Plants Develop?”
Can We Breathe in an Environment of Pure Oxygen
What happens if you breathe pure oxygen: take a look at Divers Alert Network guidelines. Scuba equipment works by forcing compressed air into the lungs at the same pressure as the pressure of the surrounding water. The deeper you dive, the more air you use. For every 33 feet / 10 meters that you descend,Continue reading “Can We Breathe in an Environment of Pure Oxygen”

Is the Skin a Tissue or an Organ?
When we study the levels of organization of the human body, we learn that cells group together to perform the same function. These groups of cells are tissues. These tissues, in turn, group to form a structure responsible for a specific function in a given system. An organ is a structure formed by several tissues.Continue reading “Is the Skin a Tissue or an Organ?”
What are pandoraviruses and why some scientists doubt they are actually viruses
When the first pandoravirus was described a few years ago, scientists were clear that they were dealing with something unprecedented. Pandoraviruses are part of the family of giant viruses and can be up to 10 times larger than a common virus, even measuring as much or more than other small bacteria. In addition, they haveContinue reading “What are pandoraviruses and why some scientists doubt they are actually viruses”
