Answer:

The correct answer is - warms, moist air rises.

Explanation:

When moist warm air rises and meets with the surface of cool air the more dense air that is cold air end up below the warm moist air in the troposphere it condenses as it rises.

The condensation of the warm, moist water leads to the formation of cloud formation. This cloud gets bigger and bigger until it precipitates and rain fall occurs.

Question 6 You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered one. All of the FI are pink. Wh
muminat

Answer:

E (Red shows incomplete dominance over white)

Explanation:

This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.

Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.

In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.
