What are the differences between tundra and taiga in regards to soil characteristics

Tundra soils are formed at high latitudes. It is usually very cold in the tundra. Tundra soils are generally frozen, and are classifed as Gelisols (think Gelato!). In order to be a Gelisol, permafrost needs to be within 100 cm of the soil surface. These soils freeze and thaw a lot, making the soil heave and buckle (cryoturbation), like a mixter does to cookie dough. This creates trees at funny angles , and can generate a lot of building issues.

The soil quality of a taiga biome is very poor. This poor quality is due to the fact that the taiga has such low temperatures for such a long period of time. Fallen leaves and moss can remain on the floor for a long time without decomposing due to the cold, moist climate. This limits their organic contribution to the soil, creating spodosol. This in turn limits the ground coverage of the forest floor.

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.
