Muscles are specialized structures in the body that perform a variety of functions. They initiate and stop movement, help maintain posture, and regulate body temperature. They also allow you to chew, swallow, urinate, and pass stool. They are made up of multiple skeletal muscle cells that are organized into a...

Mitosis: Cell Division and Reproduction Mitosis is a process in which a cell divides into two identical daughter cells. It is a vital process in organisms that need to reproduce. This is why it's important to understand how it happens, and how it can help you understand why your body grows...

By encouraging the growth of new ideas based on preexisting ones through discussion forums and inquiry, "making knowledge free and open-sourced has the potential to accelerate human development." The claim in this thesis would be the first component, which is: "Making knowledge free and open-sourced can accelerate human progress," in...

Humans are used to a particular way of life that establishes their gender roles. Therefore, a person's gender is determined by the behavior that is expected of them in a culture rather than by their biological makeup. For instance, guys are drilled from an early age to act tough, never...

Introduction Carl Sagan's 1977 book The Dragons of Eden: Speculation on Human Evolution is a work of science fiction. A variety of sciences, including anthropology and evolutionary biology, are used to try to explain the evolution of human intellect (Sagan 3). The author addresses the question of quantifying human intelligence capabilities....

Enzymes: The Biological Catalysts Enzymes are the proteins that regulate the thousands of biological reactions that take place in living organisms. They help us digest our food, conserve and transform energy, and make proteins and other cellular structures from smaller molecules. Without enzymes, most of these biochemical processes would not occur...

Death is an inevitable natural occurrence that separates the body from the soul (Druart, 2000). Humans are unable to ignore it or take any action to entirely eradicate it from society. Humans have only succeeded in delaying death by implementing procedures like the treatment of diseases and the dissemination of...

Cellular Respiration Cellular respiration is a series of metabolic processes that all living things use to convert energy stored in organic molecules, such as glucose. The process can seem complicated but is actually pretty straightforward.Photosynthetic Producers Plants and other photosynthetic producers (autotrophs) create glucose molecules by utilizing sunlight, water, and carbon dioxide...

The Cell Cycle The cell cycle is a series of regulated steps that occur in cells on the way to cell division. These stages of growth, DNA replication, and chromosome separation are timed in such a way that they produce two genetically identical daughter cells.Regulation of the Cell Cycle The cells of...

Bioengineering Bioengineering is the application of the life sciences, physical sciences and engineering principles to define and solve problems in biology, medicine, health care and other fields. The field has broad-based specializations and employs diverse professionals working in a variety of settings, including manufacturing, research facilities, government, and health care institutions.Biomedical...
