Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
The correct answer of the given question above would be option D. CHROMOSOMAL POTENTIAL. A change in the frequency of alleles in a gene pool can be explained by all of the following except the chromosomal potential. <span>A change in allele frequency is more likely to produce microevolution. Hope this answer helps.</span>
Answer: The answer is E: 'Sweetgum, a tree species with wind dispersed seeds'.
The other options mention species that occupy niche environments and would therefore definitely not be randomly dispersed. Rushes and frogs would be found along the edges of water bodies, squirrels would be found within appropriate environments, which would be acorn tree forests and orchid plants also occupy a particular tree
Explanation:
I believe this is done to ensure accuracy. DNA paternity testing involves the use of DNA profiling to determine whether two individuals are biologically parent and a child. The test establishes genetic proof whether a man is the biological father of the individual in question. There is need for use of more than one loci probes to make sure there is no error and that the results are 100% accurate.
