The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known

as haplotypes, ranging in length from 5,000 to 200,000 base pairs. There are as few as four or five commonly occurring combinations of SNPs per haplotype. Integrating what you've learned throughout this chapter and this unit, propose an explanation for this observation.

Answer:

SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level  

Explanation:

Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.

Explain how the processes of sea-floor spreading and magnetic reversal produce bands of oceanic crust that have different magnet
WARRIOR [948]

Explanation:

As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.

Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

Match the different roles of people involved in the buying center with their responsibilities.
aliina [53]

Answer:

Initiators  - identify the requirement for a product within the company

Influencers  - provide specifications about the technology needed by the company

Buyers - handle the process of choosing the vendor and negotiating the price

Explanation:

The buying centre of an organisation consists of 7 different member namely Initiators, Users, Buyers, Influencers, Deciders,  Approvers,  Gate Keepers.

  • Initiators  are the person who are first to suggests or initiates of the idea of buying the particular service or product.
  • Influencer are the whose views or idea influence the decision making process. These influencers could be  qualified engineers, technical personnel, consultants.
  • Buyers are the persons who takes care of the the person who handles the paper work of the actual purchase.These buyers plays a vital role in choosing  vendors. Sometimes they also helps in shaping the product specifications.
