Answer:
The correct answer is option C.
Explanation:
The slugs prefer pink flowers over the white ones. Thus, if the slugs are withdrawn from the population, the pink flowers are no more consumed and their number enhances. In a similar manner, the bees like to pollinate more pink flowers in comparison to the white ones.
Thus, again, the pink flowers are getting pollinated in huge concentrations. Thus, the fruits and seeds are set and they produce another generation of pink flowers. Ultimately, there would be more pink flowers in the region in comparison to the white ones as the slugs that used to consume them, are also withdrawn.
Earlier, both the numbers of pink and white flowers would remain steady as even though only some of the bees were pollinating white flowers, they were not getting consumed by the slugs. This had maintained a balance between the number of pink and white flowers. Thus, the number of pink flowers would increase with time if the slugs are removed.
Answer: option B) False
Explanation:
The body relies on SEVERAL sources for its energy or glucose supply.
Firstly, understand that Glucose could be supplied from the following:
Glycogenolysis (Glycogen break down induced by Glucagon)
Amino acids metabolism (once amine group is removed)
Fatty acid oxidation.
All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.
Therefore, the answer is False
Temperature is a measurement of the average kinetic energy of the molecules
in an object or system.
B. the warmer air contains more water vapor per unit of volume
Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
