Explanation:

5000 BC

Demonstrating some understanding of inheritance, humans worldwide begin to selectively breed more useful varieties of livestock and crops, including wheat, maize, rice and dates

400 BC

Greek philosophers contemplate the mechanisms of human inheritance. Aristotle believes that traits acquired during life, such as injuries, can be passed to offspring. He also develops the theory of “pangenesis”, which attempts to explain how these traits are transmitted via particles called “gemules” to the reproductive cells

1859

Charles Darwin, himself a proponent of pangenesis, publishes On the Origin of Species – his explanation of evolution by natural selection. Darwin provides a plethora of evidence on how valuable traits become more common in a population, but does not provide any explanation for the mechanism of transmission of these traits

 1866

Augustinian monk Gregor Mendel publishes his work on the patterns of inheritance in pea plants. His meticulous studies mark the birth of modern genetics. Mendel’s findings escape the notice of other researchers for over three decades

1882

Chromosomes are discovered by German biologist Walter Fleming, and named with the Greek prefix meaning “colour” because they become stained when cells are dyed

1902

Mendel’s research is rediscovered by botanists in 1900. US and German cell biologists then independently notice the link between Mendel’s “units of inheritance” and chromosomes. They conclude that hereditary information is contained within chromosomes

1905

The term “genetics” is created by British biologist William Bateson. The terms “gene” and “genotype” surface in 1909.

Sex chromosomes are discovered following work on butterflies and beetles

1910

US scientist Thomas Hunt Morgan is the first to discover a sex-linked trait, while studying the fruit fly Drosophila. The trait for eye colour, on the X chromosome, is also the first gene to be traced to a specific chromosome

1925

Studies show that X-rays can induce mutations in the genetic material

1944

A trio of US geneticists revisit work from the 1920s and prove that, in bacteria, DNA is the hereditary material, and not protein as was previously suspected

1951

Clear X-ray diffraction images of DNA are captured for the first time by British researcher Rosalind Franklin

1953

Building on Franklin’s work, biochemist James Watson and biophysicist Francis Crick at Cambridge University, UK, determine the now famous double-helix structure of DNA. They are awarded a Nobel prize in 1962 for their efforts.

1961

Crick and South African geneticist Sydney Brenner report that trios of DNA bases – called nucleotides – each hold the instructions for one of the 20 amino acids that combine to form proteins

1973

US researcher Herb Boyer uses enzymes to cut DNA and splice it into bacterial plasmids, which then replicate producing many copies of the inserted gene. This heralds the dawn of genetic engineering

1978

Genetically modified bacteria produce the hormone insulin

1983

The gene for an inherited disorder (Huntington’s disease) is mapped to a chromosome for the first time

1986

Kary Mullis in the US develops the Polymerase Chain Reaction (PCR), which allows researchers to produce many millions of copies of DNA molecules in just a few hours

1990

The international Human Genome Project begins, with the goal of sequencing the entire human genetic code

Gene therapy is used successfully for the first time, to treat a four-year-old girl with the rare hereditary immune disorder adenosine deaminase deficiency

1994

FlavrSavr tomatoes, genetically modified to have a long shelf-life is the first GM product to go on sale in the US. GM tomato puree goes in sale in the UK in 1996

1996

Baker’s yeast is the first (non-viral) genome to be completed, followed by the worm Caenorhabditis elegans in 1998 and then the plant Arabidopsis and fruit fly Drosophila in 2000

2000

Completion of the draft human genome is jointly announced by US firm Celera Genomics and the Human Genome Project (an international public consortium). The full sequence – comprising 30,000 to 40,000 genes – is completed in 2003

2003

A tropical fish that fluoresces bright red becomes the first genetically modified pet to go on sale in the US

Answer:

In this relationship , the role of wolves is  as Secondary Consumers .

Explanation:

A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.  

A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).

PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.

SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.  

In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are  producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .

Hence, the correct answer is  OPTION D.

Answer:

C

Explanation:

C would allow you to understand the cause of why specific people got the disease, and the comparison between those who got it and didn't would be vital in determining why some people got it in the first place.

Here, we are required to explain how the electronic configuration can be used to determine the number of Valence electrons.

Valence electrons simply refers to electrons present in the outermost shell of an element.

Valence electrons simply refers to electrons present in the outermost shell of an element.The electron configuration is a representation of the arrangement of electrons in the atomic orbitals of an element.

Fir instance: the electron configuration of potassium; 1s² 2s² 2p⁶ 3s² 3p⁵

The algebraic sum of electrons in the energy level 3 therefore is the number of Valence electrons.
