lesya [120]3 years ago
6 0
The best answer is option D. Acid rain is simply rainfall that has been rendered acidic due to water vapor reacting with nitrogen oxide ad sulphur dioxide very high up in the atmosphere. Acid rain is not only a threat to the ecosystem and environment, but also seriously damages buildings and sculptures. Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid. Concrete surfaces and paint finishes are also seriously damaged by acid rain.

kow [346]

Answer:

C. 1/4

Explanation:

Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=

9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.

Therefore, the proportion of the progeny with long horns = 4/16= 1/4
