Answer:

The belief that organisms originate from a common ancestor was much of the basis that the theory of natural selection was based on. Evidence of animals sharing the same trait, even though for some it appears to have no benefit to them, appears to have been at the root of this belief.

Charles Darwin was the first scientist to publish a coherent theory of Evolution by Natural selection. He wasn't the first to intuitively suspect that species evolved from a common ancestor, but he was the first to publish a coherent theory and bring forth evidence for it.

The information in the table shows the possible genotypes resulting from the mating of two heterozygotes aadd. the allele a code
tensa zangetsu [6.8K]
Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.

A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy

Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.

A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
