Answer:
I believe whale fossils were found.
Answer: a. boiler - I. part of a coal-fired power plant.
b. combustion chamber - I. part of a coal-fired power plant.
c. condenser - III. part of a coal-fired power plant and part of a nuclear power plant.
d. control rod - I. part of a coal-fired power plant.
e. generator- III. part of a coal-fired power plant and part of a nuclear power plant.
f. turbine - III. part of a coal-fired power plant and part of a nuclear power plant.
Explanation:
a. Boiler: It is used in the coal power plant to heat the water used for producing electricity. The boiler keeps the temperature of water or steam at a desired level.
b. Combustion chamber: It is used for combustion of coal and using thermal energy for electricity generation.
c. Condenser; It is used in both nuclear and coal power plants. It condense and receive from the turbine.
d. Control rod: It is used in the nuclear power plant for controlling the nuclear fission and fusion reactions of heavy metals.
e. Generator: It converts the thermal energy into electrical energy.
f. Turbine: The turbine blades move with the effect of steam or any form of energy and the energy so produce is used for generating electricity in generator.
Answer:
B: beaks, finches.
Explanation:
Beaks, finches. This is because he noticed that fruit-eating finches had beaks similar to parrots, while finches that ate insects had narrow beaks. The difference in their beaks is due to adapting to different environments which causes them to evolve into different species of finches.
