The dominant trait is hornless. 

If this is correct, then the original bull is a heterozygote:
H = hornless
h = horned
Bull is Hh

Cross 1: Hh x hh (horned female) - offspring is hh (horned)

Cross 2: Hh x Hh (hornless female) - offspring is hh (horned)

Cross 3: Hh x hh (horned female) - offspring is Hh (hornless)

Cross 3 is the key to confirming this because the only way to get a hornless offspring would be if hornless is recessive.

Compare biomes of North Africa and iceland
Travka [436]

Answer with Explanation:

"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.

The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.

Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."
