The geologic time scale is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships of events that have occurred during Earth’s history. It divides Earth’s history into a number of time intervals, each of which is characterized by … Read more
In nuclear chemistry, a nuclear decay equation is a mathematical representation of the process of radioactive decay. It shows the starting isotope (the unstable nucleus), the products of the decay (the stable nucleus and any other particles or radiation emitted), and the types of decay that have occurred. There are three main types of radioactive … Read more
The pH and pOH of a solution are measures of the acidity or basicity of the solution. The pH of a solution is a measure of the concentration of hydrogen ions in the solution, with a lower pH indicating a higher concentration of hydrogen ions and a higher pH indicating a lower concentration of hydrogen … Read more
The circulatory system is a body system that is responsible for pumping and distributing blood, oxygen, and nutrients to the body’s cells and tissues. It is made up of the heart, blood vessels, and blood. The main functions of the circulatory system are to transport oxygen and nutrients to the body’s cells and tissues, remove … Read more
Potential energy is the energy that an object possesses due to its position or state. It is the energy that an object has the potential to release or convert into other forms of energy. There are several types of potential energy, including gravitational potential energy, elastic potential energy, and chemical potential energy. Gravitational potential energy … Read more
Mitosis is the process by which a cell divides into two daughter cells. It is an essential part of the cell cycle and is necessary for the growth and repair of tissues in living organisms. During mitosis, the nucleus of the cell divides into two identical copies, and the cytoplasm of the cell is divided … Read more
Nuclear equation In nuclear chemistry, a nuclear equation is a mathematical representation of a nuclear reaction, which is a process that involves changes to the nucleus of an atom. A nuclear equation shows the reactants (the atoms or isotopes that are involved in the reaction) on the left side of an arrow and the products … Read more
A food web is a network of interconnected food chains in an ecosystem. It shows the feeding relationships between different species in an ecosystem, how energy and nutrients are transferred between them, and how the relationships between species change over time. A food chain is a simplified version of a food web that follows a … Read more
