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.

Describe three examples of materials that have resulted from a lack of decomposer activity
erastova [34]

The decomposers are of two kinds, aerobic decomposers and anaerobic decomposers. The aerobic decomposers need the oxygen from the air to break down the dead and decaying matter into simple salts, sugars and hydrocarbon gases. The anaerobic decomposers do not require oxygen for the break down of dead and decaying matter. They break down the matter into various forms of hydrocarbons, sulphides and nitrogenous compounds.

When a dead and decaying matter gets buried deep within the Earth where there is an absence of the decomposers, it takes the form of crude oil, coal, peat, asphalt, and natural gas. The matter gets compressed by the weight of the rocks above and changes its form.
