Answer:
A. a lamp being turned on
B. a toaster being used to toast bread
D. a car horn honking
Explanation:
Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.
From the examples given in this question, the following are examples of scenarios that involve energy transformation:
- A lamp being turned on: This converts chemical energy to light energy.
- A toaster being used to toast bread: This converts electrical energy to heat energy.
- A car horn honking: This converts electrical energy to sound energy.
Note that, melting of a chocolate does not transform any form of energy.
Answer:
No, there are no differences
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide chains that interact together in order to form a double helix. This molecule (DNA) carries the genetic instructions that make each species unique. In DNA, each polynucleotide chain is composed of nucleotide monomers: a nucleotide is composed of a deoxyribose sugar attached to a phosphate group and one nitrogen-containing base (i.e., adenine, thymine, guanine and cytosine). This basic structure is the same among different species, and, therefore, genetic differences between different groups (in this case, animals, plants, and bacteria) are caused by differences in the nucleotide-base sequences of their DNA molecules.
Radon and Thoron are the most significant sources of radiation exposure to people living in the United States accounting for 37% of total radiation exposure.
These are nuclides that are produced from the radioactive decay of materials especially in consumer products and through natural processes such as the decay of radium.
