Answer:
smartphone cameras
Explanation:
The development of smartphones and better photography options on them have impacted the industry of cameras. This is a quickly dying business that in decline from 2010.
Ever since smartphones started developing, the cameras on them started getting better and better. People did not need to buy separate cameras that were much heavier and bigger than phones. <u>Phones are usually on us all of the time and it is easier to carry one object instead of two.</u>
<u>Therefore, people stopped buying separate cameras for taking pictures. </u>Last year there was the smallest number of cameras sold ever since 2001. which shows how fast and rapid drop in sales is.
Genetics is the study of heredity and variations. Heredity and variations are controlled by genes—what they are, what they do, and how they work. Genes inside the nucleus of a cell are strung together in such a way that the sequence carries information: that information determines how living organisms inherit various features (phenotypic traits). For example, offspringproduced by sexual reproduction usually look similar to each of their parents because they have inherited some of each of their parents' genes. Genetics identifies which features are inherited, and explains how these features pass from generation to generation. In addition to inheritance, genetics studies how genes are turned on and off to control what substances are made in a cell—gene expression; and how a cell divides—mitosis or meiosis.
Some phenotypic traits can be seen, such as eye color while others can only be detected, such as blood type or intelligence. Traits determined by genes can be modified by the animal's surroundings (environment): for example, the general design of a tiger's stripes is inherited, but the specific stripe pattern is determined by the tiger's surroundings. Another example is a person's height: it is determined by both genetics and nutrition.
Chromosomes are tiny packages which contain one DNA molecule and its associated proteins. Humans have 46 chromosomes (23 pairs). This number varies between species—for example, many primates have 24 pairs. Meiosis creates special cells, sperm in males and eggs in females, which only have 23 chromosomes. These two cells merge into one during the fertilization stage of sexual reproduction, creating a zygote. In a zygote, a nucleic acid double helix divides, with each single helix occupying one of the daughter cells, resulting in half the normal number of genes. By the time the zygote divides again, genetic recombination has created a new embryo with 23 pairs of chromosomes, half from each parent. Mating and resultant mate choice result in sexual selection. In normal cell division (mitosis) is possible when the double helix separates, and a complement of each separated half is made, resulting in two identical double helices in one cell, with each occupying one of the two new daughter cells created when the cell divides.
Chromosomes all contain DNA made up of four nucleotides, abbreviated C (cytosine), G (guanine), A (adenine), or T (thymine), which line up in a particular sequence and make a long string. There are two strings of nucleotides coiled around one another in each chromosome: a double helix. C on one string is always opposite from G on the other string; A is always opposite T. There are about 3.2 billion nucleotide pairs on all the human chromosomes: this is the human genome. The order of the nucleotides carries genetic information, whose rules are defined by the genetic code, similar to how the order of letters on a page of text carries information. Three nucleotides in a row—a triplet—carry one unit of information: a codon.
The genetic code not only controls inheritance: it also controls gene expression, which occurs when a portion of the double helix is uncoiled, exposing a series of the nucleotides, which are within the interior of the DNA. This series of exposed triplets (codons) carries the information to allow machinery in the cell to "read" the codons on the exposed DNA, which results in the making of RNA molecules. RNA in turn makes either amino acids or microRNA, which are responsible for all of the structure and function of a living organism; i.e. they determine all the features of the cell and thus the entire individual. Closing the uncoiled segment turns off the gene.
Martin Luther had great impact on the worship and musical life of early Lutheranism. He was an accomplished musician, a singer, a lute player, and one who knew much of the music and many of the musicians of his day. He wrote to support the adequate funding of church music, the musical education of children in the schools, and the musical education of pastors and teachers. He wrote new hymns as well as "corrected and improved" older hymns. He composed at least one short polyphonic motet, "Non moriar sed vivam" ("I shall not die, but live"). When it came to worship and the liturgy, he continued the basic pattern and tradition of the medieval Mass with two exceptions. He deleted the Canon of the Mass and the prayers at the Offertory. Luther's basic approach was to retain whatever past traditions were not contrary to his understand of the Gospel. Luther advocated certain new reforms that included the use of vernacular congregational song as an integral part of the liturgy, the importance of the sermon, and communion in both kinds. Throughout all his liturgical and musical reforms, Luther always sought to demonstrate the continuity and unity of the reforming movement with the church catholic. The Reformation was born when Renaissance polyphony was the prevailing musical style. It is exemplified in the music of Dufay and Binchois and culminated in the music of Heinrich Isaac and the renowned Josquin Desprez. This style was characterized by imitative pholyphony. It usually was based on the foundation of Gregorianmelodies normally found in the tenor part. This musical style, with words associated with melodies, reflected Luther's understanding that the Word of the Gospel was to be presented simply and preoclaimed musically in an objective fashion and not to be "interpreted" <u>Carl Shalk</u>The turbulent days of the church of the early Reformation and its dire struggle with the Roman Catholic church were past. The Reformation made worshipers aware of the "Priesthood of All Believers." In the 17th century, people in the Lutheran congregations continued to participate actively in worship. More congregations now had printed hymnals. Composers wrote music that built upon the old traditions, but also incorporated the new styles that were emerging. Settings of Gospel motets gave people the opportunity to conitinue to hear the Word in traditional polyphonic settings called the "first practice." Instruments and voices of the choir and congregation joined in stimulating settings of chorales. Congregations often sang stanzas in alternation with choral and instrumenal stanzas. Magnificent polychoral settings of chorales and Psalms were written for several choirs of voices and instruments. The organ continued to introduce congregational and liturgical song. The chorale prelude grew in importance as a vehicle to introduce chorale singing. As time passed, organs began to accompany congregational song. Under the influence of developments in the madrigal and opera, concerted music of the "second practice" became a part of church music. The basso continuo and monody were adapted to compositions for worship. The organ and instruments assumed new roles in concerted writing. Choral music and congregational song changed, reflecting a new emphasis on personal peity and the expressive capability of concerted music. Four masters of Lutheran church music provided leadership for a growing and vigorous practice. early in the century, Michael Praetorius wrote splendid chorale arrangements and polychoral settings for voices and instruments. Johann Hermann Schein wrote in the old polyphonic style, but also developed the scared madrigal in the concerted style. Samuel Scheidt was the first great Lutheran organist and composer. Heinrich Schütz, the most renowned composer of his time, contributed masterworks in all styles of sacred vocal music.Carlos Messerli The 18th Century...
