Answer:

Genetics

Explanation:

The color of the apple arises from the level of expression of certain genes in your skin or peel

Enzymes work together to convert certain molecules into pigments called anthocyanins, the same class of substances that give purple sweet potatoes, grapes and plums their color. The levels of these enzymes are controlled by a transcription factor, a protein that regulates the expression of a gene called MYB10, so that the more MYB10 there is, the redder the shell will be in general.

If a red apple is illuminated with a blue light, it probably looks like a violet color. This is because the combination of colors (both in paints, red and blue, or in this case the superposition of tones) results in a bruised tone.

In white light, a red apple absorbs all the colors (including green) of the spectrum except red, which it reflects. When the green light shines on a red apple, the red apple absorbs the green light. Since there is no red light shining on the apple, there is no red light to reflect, so the apple appears black.

Answer:

When the Hawaiian islands were formally annexed by the United States in 1898, the event marked end of a lengthy internal struggle between native Hawaiians and white American businessmen for control of the Hawaiian government. In 1893 the last monarch of Hawaii, Queen Lili'uokalani, was overthrown by party of businessmen, who then imposed a provisional government. Soon after, President Benjamin Harrison submitted a treaty to annex the Hawaiian islands to the U.S. Senate for ratification. In 1897, the treaty effort was blocked when the newly-formed Hawaiian Patriotic League, composed of native Hawaiians, successfully petitioned the U.S. Congress in opposition of the treaty. The League's lobbying efforts left only 46 Senators in favor of the resolution, less than the 2/3 majority needed for approval of a treaty. The League's victory was shortlived, however as unfolding world events soon forced the annexation issue to the fore again. With the explosion of the U.S.S. Maine in February of 1898 signaling the start of the Spanish American War, establishing a mid-Pacific fueling station and naval base became a strategic imperative for the United States. The Hawaiian islands were the clear choice, and this time Congress moved to annex the Hawaiian islands by Joint Resolution, a process requiring only a simple majority in both houses of Congress. On July 12, 1898, the Joint Resolution passed and the Hawaiian islands were officially annexed by the United States.

The Hawaiian islands had a well-established culture and long history of self-governance when Captain James Cook, the first European explorer to set foot on Hawaii, landed in 1778. The influence of European and American settlers quickly began to alter traditional ways of life. Originally governed by individual chiefs or kings, the islands united under the rule of a single monarch, King Kamehameha, in 1795, less than two decades after Cook's arrival. Later the traditional Hawaiian monarchy was overthrown in favor of a constitutional monarchy. Eventually, the monarchy itself was abandoned in favor of a government elected by a small group of enfranchised voters, although the Hawaiian monarch was retained as the ceremonial head of the government. Even elements of daily life felt the social and economic impact of the white planters, missionaries and businessmen. The landholding system changed, and many aspects of traditonal culture were prohibited including teaching the Hawaiian language and performing the native Hula dance.

In 1887, the struggle for control of Hawaii was at its height as David Kalakaua was elected to the Hawaiian throne. King Kalakaua signed a reciprocity treaty with the United States making it possible for sugar to be sold to the U.S. market tax-free, but the haole - or "white" - businessmen were still distrustful of him. They criticized his ties to men they believed to be corrupt, his revival of Hawaiian traditions such as the historic Hula, and construction of the royal Iolani Palace. A scandal involving Kalakaua erupted in the very year he was crowned, and it united his opponents, a party of businessmen under the leadership of Lorrin Thurston. The opposition used the threat of violence to force the Kalakua to accept a new constitution that stripped the monarchy of executive powers and replaced the cabinet with members of the businessmen's party. The new constitution, which effectively disenfranchised most native Hawaiian voters, came to be known as the "Bayonet Constitution" because Kalakaua signed it under duress.
