Loss of habitat has decreased the population and number of alleles of Canadian lynx. A few survivors migrated to other forests and multiplied, but there is less genetic variation in the offspring. Which statement is true about this event?

Answers

Reproductive isolation prevents variations from spreading throughout the entire population. Since genetic variations basically occur randomly, the chances that the same variations will occur in both reproductively separated subpopulations are vanishingly slim. Thus, genetic divergence between both subpopulations will occur, and this may eventually lead to speciation. Isolation stops populations of the same species from interbreeding. This results in separate breeding among populations and genetic differences become more pronounced with each generation.

Which is the best example of a scientific discovery resulting from new technology?*the discovery that elements can be grouped in a table on the basis of their properties
*the discovery of atomic structure which led to the development of an electron microscope
*the discovery of the structure of DNA, which occurred as the result of an X-ray image of a DNA molecule
*the discovery that plant pigments can be separated and identified by using paper and a solvent

Answers

Answer: Option C

Explanation:

The discovery of the structure of DNA was done with the help of Technique named X-ray crystallography. The structure of the DNA was created by the diffraction pattern that was produced by the x-ray crystallography.

This method was used to find the structure of the DNA that was used to study more properties of the DNA.
