Geomagnetism is the study of the dynamics of the Earth's magnetic field, which is produced in the inner core. The Earth's magnetic field is predominantly a geo-axial dipole, with north and south magnetic poles located near the geographic poles that undergo periodic reversals and excursions.

Answer:

Geomagnetism is the part of geology that looks at the dynamics of the Earth's magnetic field. These dynamics are produced by the Earth’s inner core. The Earth has two poles (North and South) which can undergo reversal and movement (excursions).

If two intermediate-colored chickens together produced 100 chicks, how many would you expect to be black?

sergiy2304 [10]

Answer: 25 of the chicks will be black

Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.

Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.
