Environmental Science – Astronomy: Moon and Sun

Welcome back to our next blog post on astronomy! The moon's formation is theorized by two theories. The simultaneous formation theory said that the Earth and the Moon formed at the same time, around 4.6 billion years ago. The impact theory states an object collided with the Earth breaking the Earth apart into the planet [...]

Environmental Science – Astronomy: Stars

Stars are large incandescent bodies. Stars radiate electromagnetic, heat, and light energy which produces their light. Hotter stars glow with shorter wavelength lights making them blue in color. Stars are held together by gravity. Hydrogen combines through fusion reactions producing energy and forming Helium. The lifestyle of a star is as shown below: Stars begin [...]

Environmental Science – Astronomy: The Solar System

Hey guys welcome to the next APES blog post! This is going to a an astronomy sub-series. Our universe contains billions of galaxies, groups of millions of starts held and bound by gravitational forces. Our galaxy is the milky way galaxy. Gravity forms planets and stars by forcing and moving around dust clouds and debris [...]

The Respiratory System

Welcome back to the systems blogs! The respiratory system has the major function of gas exchange, the uptake of oxygen from the environment and the release of carbon dioxide into the environment. Organs imporant in this system are blood vessels, lungs, diaphragm, heart, and the nose. Alveoli are functional units in this system located in [...]

Digestive System

The digestive system has the function of breaking down food to retrieve nutrients and minerals for use such as energy and filter out waste. Major organs include the intestines (small and big), stomach, esophagus, liver, mouth, gallbladder, pancreas, etc. Functional units include muscles and sphincters, muscular layer modified into ring-like valves at junctions in segments [...]

The Immune System

The immune system has the major function of defending the body from invaders such as pathogenic bacteria and viruses which can lead to diseases, sicknesses, and death. The functional unit of this system are white blood cells called lymphocytes and antibodies that have the ability to attach to microbes and mark them for death and [...]

Multicellular Development

A new finding recently at the University of Queensland has unearthed some secrets about the origins of multi-cellular animals. As you all know, a multi-cellular organism is composed of multiple cells, just like us humans, but at first life was unicellular. Professor Bernie Degnan used new technology to find out that the first multi-cellular animals [...]

The Reproductive System

Welcome back, today's topic is the reproductive system. This has the major function of reproducing offspring of a species to continue its survival. Major organs include the vagina, penis, ovary, and testes, with functional units such as eggs and sperm produces by meiosis. The female human goes through a menstrual cycle where ovulation occurs at [...]
