Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant. The fruit color of eggplants is another example of incomplete dominance.
A volcanic winter is a reduction in global temperatures caused by volcanic ash and droplets of sulfuric acid and water obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, particularly explosive volcanic eruption.
Answer: Option b
Explanation:In chemistry,
before any reaction would occurs, reactat must be able to overcome some certain amount of energy which is called the activation. The activation energy is usually the heat that is suppled.it is also refered to as the minimum energy needed before any reaction can take place. For reaction to take place, there must be an equilibrium( at constant temperature and pressure.

Phrenology is the study of the brain by looking at the size and the shape of cranium i.e., the skull. The study relies on empirical evidences that someone intelligent will have a bigger brain or will have a larger skull than a average person. These evidences however have no biological proof as they were not examined by conducting experiments. The study also rejected unsupported claims that a person with a smaller brain or skull size can be intelligent. Hence such a study or phrenology is considered a pseudoscience.
