If someone injuries their hand, the damaged tissues will eventually heal. Hair and nails grow regularly. Cells in the gastrointestinal tract lining also renew every three to five days. Each of these regenerative processes requires cells to grow and divide. Just like everything else that is living, cells have a life cycle that includes growth and propagation. Understand the cell cycle phases. See descriptions of each stage of mitosis and understand what happens during interphase. Learn the importance of cell division !

All organisms grow during their lifetime. Some growth happens slowly, and some happen quickly, depending on the species. However, no matter the rate of growth, being able to grow is a trait that all living things have in common. How are organisms able to grow? Eukaryotic organisms, or organisms that are multicellular and include plants, animals, and fungi, grow through a process called mitosis. What is mitosis ? Learn what is meant by mitosis and its function. Understand various stages of mitosis, the purpose of mitosis, and discover what happens during mitosis of a cell !

The name Charles Darwin is widely recognized across the world, but who is Charles Darwin, really? Darwin was and still is a prominent figure in the world of science. Darwin is considered the father of evolution. A field naturalist who spent five years circumnavigating the world aboard the ship the HMS Beagle, he collected notes and data that would later lead to revolutionary discoveries. Although evolution had already been introduced as a scientific theory, Darwin went beyond this and presented the scientific theory of evolution through natural selection. His contributions to science and biology are still taught and referred to in scientific works !

In biology, evolution refers to the process of organisms developing and changing over time. Explore the theory of evolution and review evidence that supports it found in paleontology, biogeography, embryology, comparative anatomy, and molecular biology !

The field of paleontology is important to the support and understanding of evolution. This is the study of prehistoric life, including fossils, footprints, and past climatic events. As organisms die, they become part of the ground. Often they leave behind bones and imprints, which allow us to see what they looked like millions of years later !

Species living today are descendants of species from long ago. Charles Darwin observed this phenomenon and described it as descent with modification. Evolution occurs on a large scale over a very long time, but it is not unlike you and your parents. You are a descendant of your parents but in a modified version; you are not exactly like them even though you came from a combination of their genes !

We consume food to nourish ourselves, as well as to satisfy and feel pleasure. According to their origin, composition and function, foods are classified.
RNA transcription or simply stated as transcription is the first step of gene expression. The RNA molecule produced by the transcription process act as a messenger of the genetic information from DNA to the protein. Learn about mRNA transcription. Discover where and how DNA is transcribed into RNA and compare between DNA and RNA !

One of the most enjoyable things about building something is getting to use all the cool tools. Builders use power saws, drills and electric sanders to turn raw materials into unique creations. Just like builders, scientists use tools to get the results they want. Scientific tools help scientists take precise measurements, carry out experiments and make observations. In this lesson, we will learn about some common scientific tools that you might encounter in your school's science lab as well as some more advanced tools scientists in the life sciences are using to investigate the world around us.

In the mid-19th century, a man came up with a very powerful idea, the idea that species could change. Today, all the time, we hear about animals adapting, endangered species going extinct, viruses mutating. One man looked past all that. His name was Charles Darwin.Darwin called his idea the theory of natural selection !

The theory of evolution via natural selection can be summed up in this way: Conditions of a habitat will naturally select for characteristics that will increase the chances of survival of organisms in a specific environment. Charles Darwin is credited with this theory, though you may be amazed at how much work preceded his revolutionary ideas about the origin of species by many other important scientists . Darwin chose the term natural selection to differentiate it from artificial selection, or the intentional breeding of animals to favor particular phenotypic traits. Let's know more about it !

Plants have a power we humans can only dream of - making food from sunlight. Sure, we can cook some savory dishes, but we use food already made, mostly by plants. This process of assembling carbohydrates fueled by the power of sunlight is called photosynthesis.
Keep in mind that the sun emits all sorts of different kinds of energy, such as heat and gamma rays, but photosynthesis specifically captures light energy. In addition, photosynthesis generates basic sugar molecules called glucose, which can be used to build more complex carbohydrates. Let's know more !
As the population size increases, the resources needed to sustain the growing population also increase. Understand the impact of population size on resource consumption and discover the ecological footprint levels of different population sizes.
