Answer:

The correct answer is option A. "Line spectra".

Explanation:

Line spectra is a method that is used to determine the temperature of a star. Line spectra is based on the principle that, depending on the temperature of a star, a line is traced which is compared to the continuum temperature that could either generate a emission (hotter) or absorption (colder) line. A spectrum of lines depending on the temperature have been established under the code  OBAFGKM, where O is the hottest an M is coldest.

Bear pigmentation is subject to epistasis of the B alleles by the d alleles. B (black) is dominant over b (brown). D is dominant
White raven [17]

Answer:

9/16 black, 3/16 brown, 4/16 white

Explanation:

             BD         Bd          bD         bd

BD     BBDD      BBDd     BbDD     BbDd

Bd      BBDd      BBdd     BbDd      Bbdd

bD      BbDD     BbDd      bbDD     bbDd

bd       BbDd    Bbdd       bbDd     bbdd

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.

To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.

The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.

The coolest and dimmest space objects emit radiation of longer wavelengths than those we can see. A detector for which type of e
BARSIC [14]

Answer: The infrared radiations can detect the coolest and dimmest space objects.

In general, the coolest and darkest regions of space emit radiations of longer wavelengths. The Infrared telescope is used to find the cool, dim stars by slicing the interstellar dust bands and also measure the temperature of the planet of the solar system. The coldest stars do not emit light so they can be seen with the infrared telescopes only. In the visible region, blue stars are hottest and red are the coolest. The wavelength is inversely proportional to the energy emitted so the hottest stars are in the region of low wavelength in visible region.
