Jupiter is composed primarily of gaseous and liquid matter. It is the largest of four gas giants as well as the largest planet in the Solar System with a diameter of 142‚984 km at its equator. The density of Jupiter‚ 1.326 g/cm3‚ is the second highest of the gas giant planets. The density is lower than any of the four terrestrial planets. Jupiter’s upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume or fraction of gas molecules. Since a helium atom has about

Scalpel A scalpel‚ or lancet‚ is a small and extremely sharp bladed instrument used for surgery‚ anatomical dissection‚ and various arts and crafts (called a hobby knife). Scalpel blades are usually made of hardened and tempered steel‚ stainless steel‚ or high carbon steel. Surgical scalpels consist of two parts‚ a blade and a handle. The handles are reusable‚ with the blades being replaceable. In medical applications‚ each blade is only used once (even if just for a single‚ small cut). Scalpel

Environmental Protection and Conservation of the Ecosystem We‚ the human beings‚ are living in a polluted environment‚ and it is getting worse day by day. There is nothing else to blame but ourselves. We are suffering from our own negligence. God has given us everything we need but all we do is to ruin His beautiful creation. If we do not want to see the future to suffer‚ it is not yet too late to act. By just doing the simple ways‚ we can help protect the environment. Every one of us has a

Bottle Biology Project I made a two-layered bottle ecosystem. In the bottom layer‚ there is an aquatic ecosystem. In the aquatic ecosystem‚ there is one organism; a goldfish. In the top layer‚ there is a land ecosystem. There are many plants and other pudding flowers. This is a good example of two organisms from different ecosystems. There were not as many steps as I thought there would be involved in building the bottle itself. First I emptied out two two liters of pop. I then cut

The food web of the snakes and other organisms in an ecosystem helps to show how the snakes live in their habitats and help make a community. Snakes are simple animals. These non-venomous constrictors use their forked tongue to detect different odors from their prey. The Ball Python strikes with great velocity and kills by constriction. The snake’s diet is a great help in ecosystems by keeping

CONSERVE/TAKE CARE THE ECOSYSTEM The value of ecosystem services Through its ecosystems‚ planet earth provides mankind with resources such as food‚ climate regulation‚ fresh water and clean air. Without these resources‚ which we call ecosystem services‚ life on earth is not possible. Currently‚ we are using per annum 1.5 times the amount of ecosystem services which the planet can provide us with sustainably. As a result of this ’overuse’‚ the capacity of the earth’s ecosystems to provide these crucial

The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries throughout the Second World War. The Spitfire continued to be used as a front line fighter and in secondary roles into the 1950s. It was produced in greater numbers than any other British aircraft and was the only British fighter in continuous production throughout the war.[5] The Spitfire was designed as a short-range‚ high-performance interceptor aircraft[6] by

Ecology Essay African lions play a big role in the ecosystem. They are at the top of the food chain and are responsible for 85% of predation in their habitat. They prey on herbivores such as buffalo‚ antelope and zebras. The African lion’s biome is in the tropical grassland and their habitat is the grassy plains of the African savanna. Without the lion‚ the ecosystem would be unbalanced and unstable. The African lion‚ being at the top of the food chain‚ interacts with other organisms in many
