The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle. In one tho two sentences, explain whether or not the reaction is balanced.

Answers

Answer 1

The equation is balanced because the mass and charge are equal on both sides of the reaction equation.

In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.

The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

What is the role of density changes in a convection cycle

Answers

Answer:

Explantion

Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks. ... Air from above the ocean is colder and more dens

Convection is the transfer of heat caused by a density difference within a fluid. Water becomes less dense and rises as its temperature rises in the presence of a heat source.

What is convection?

Convection is a method of moving heat that is also known as a heat transfer mechanism. When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.

Differential heating causes convection currents. Warmer (less dense) material rises, while cooler (more dense) material sinks.

This movement is responsible for the formation of circulation patterns known as convection currents in the Earth's atmosphere, water, and mantle.

Convection is the heat transfer resulting from variations in density within a fluid. In the presence of a heat source, water becomes less dense and rises in density.

Thus, this is the role of density changes in a convection cycle.

What are the 6 kingdoms of life? Provide an example for each.

Answers

Answer:

Archaebacteria

Archaebacteria are the most recent addition to the kingdoms of organisms. Their existence was not discovered until the 1980s. However, Archaebacteria are the oldest known living organisms. They are single-celled and thrive in extremely hot boiling water found in environments like volcanic thermal vents in the ocean and hot springs like the geysers at Yellowstone Park. Some species also live in very salty environments such as The Dead Sea and The Great Salt Lake.

Eubacteria

Eubacteria are also single-celled bacterial organisms. This kingdom makes up most of the bacteria in the world. Eubacteria are very common and well-known to us as parasites like Streptococci which causes strep throat. However, these bacteria also help produce many antibiotics, vitamins and yogurt.

Fungi

The Fungi kingdom is recognizable to us as mushrooms, molds, mildews and yeasts. Unlike the organisms in the Archaebacteria and Eubacteria kingdoms, Fungi are multi-celled organisms. Early scientists classified mushrooms and other fungi in the Plant kingdom but they do not produce their own food as plants do.

Protista

Protista or Protozoa are single-celled organisms, but are more complex than single-celled bacteria. The Protista kingdom includes algae and slime molds. Any microscopic organism that does not fall into the bacterial, fungi, plant or animal kingdoms is considered a part of the Protista kingdom.

Plants

The Plant or Plantae kingdom encompasses all flowering plants, mosses and ferns. Plants are multi-celled, complex organisms and are considered Autotrophic. This means that plants create their own food through photosynthesis. The Plant kingdom is thought to be the second largest with over 25,000 known species.

Animals

The largest kingdom of organisms is the Animal or Animalia kingdom. This kingdom is made up of complex, multi-celled organisms ranging from sea sponge colonies to elephants. All organisms in the Animal kingdom are Heterotrophs meaning, unlike plants which produce their own food, animals feed upon other organisms. The Animal kingdom is the world's largest with over one million known species.
