Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.
Answer:
A key feature of animal body plans is that they can show multiple types of symmetry.For example,,a dog would represent bilateral symmetry,while a jellyfish and other cnidarians would represent <u><em>radial symmetry</em></u>.
Explanation:
In biology, symmetry can be described as the balanced distribution of the body shape of an organism.
Radial symmetry can be described as a symmetry which depends on a central axis. The symmetry of cnidarians depends on a central axis hence they have radial symmetry.
Bilateral symmetry can be described as a symmetry in which the two halves of the symmetry are mirror images of one another. For example, humans, dogs etc.
