What is the difference between a hypothesis and a theory

Biology
1 answer:
Ivan3 years ago
5 0

Answer: A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.

When farmers leave plant stalks in the field to reduce soil erosion, it is called ____. a. contour farming c. no-till farming b.
aleksklad [387]

Answer:

Option (C)

Explanation:

In no-till farming method, the farmer usually uses a no-till planter with the help of which they make a narrow type of trench that is sufficient enough for the seed to be grown in rows. The residue of the cover crop is allowed to place on the surface of the soil by not plowing, as a result of which the soil is protected from getting eroded and losing of moisture content. This improves soil quality.

This method helps in increasing the water content that percolates down into the soil, holding the organic matter and recycling of nutrient matters. It also expands the growth and population of microbes in the soil, which provides more nutrients to the soil and increases the fertility of the soil.

Thus, when a farmer leaves plant stalks in the field to reduce soil erosion, then it is known as no-till farming.

Hence, the correct answer is option (C).

Assume that in cattle a spotted coat is dominant to an even coat, short horns are dominant to long horns, and the traits for coa
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
