## Electricity

Electricity Everything is made up of atoms. Each one of them has three particles : protons, neutrons and electrons. Electrons spin around the center of an atom. They have a negative charge. Protons, which are in the center of atoms, have a positive charge. Normally, an atom has as many protons as it has electrons. It is stable or balanced. Carbon, […]

## Polymerase Chain Reaction (PCR)

Polymerase Chain Reaction (PCR) Polymerase chain reaction (PCR) is a method widely used in molecular biology to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. PCR was invented in […]

## The Female Reproductive System

The Female Reproductive System The female reproductive system is designed to carry out several functions. It produces the feminine egg cells necessary for copy, known as the ova or oocytes. The system is meant to move the ova to the positioning of fertilization. Conception, the fertilization of associate degree egg by a sperm, commonly happens […]

## The Male Reproductive System

The Male Reproductive System The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport gamete (the male fruitful cells) and protecting fluid (semen) To discharge gamete among the feminine fruitful tract throughout sex To produce and secrete male sex-hormones chargeable for maintaining the male […]

## Camera Calculator – Photomath

Photomath Photomath could be a mobile application represented as a “camera calculator”, that utilizes a phone’s camera to recognize mathematical equations and to show the gradual answer onscreen. it’s out there at no cost on Google humanoid and iOS. The application was free in 2014 by Micro-blink, an organization primarily based in Zagreb, Croatia, with […]
