Step 1: Identify Key Factors for Natural Selection.
For natural selection to act on a trait, it must confer a fitness advantage, vary among individuals, and be heritable.
Step 2: Analyze Each Condition.
(A) If increased nectar production leads to greater fruit set and more offspring, it provides a reproductive advantage, a key component of natural selection.
(B) Variation in nectar production across individuals allows natural selection to favor those with optimal nectar production.
(D) Heritability of nectar production ensures that beneficial traits are passed to the next generation, allowing natural selection to act over successive generations.
Consider the following figure of sequence divergence over time. The dashed and solid lines represent synonymous and non-synonymous substitutions, respectively. Which one or more of the following does the figure support?
The figure below shows the reproductive success of two alternative mating strategies, with respect to their frequency in the population. Territorial males (solid line) defend territories to get mates, and Sneaker males (dashed line) obtain mating opportunities without having territories. Which one or more of the following conclusions can be drawn from this figure?
The 12 musical notes are given as \( C, C^\#, D, D^\#, E, F, F^\#, G, G^\#, A, A^\#, B \). Frequency of each note is \( \sqrt[12]{2} \) times the frequency of the previous note. If the frequency of the note C is 130.8 Hz, then the ratio of frequencies of notes F# and C is:
Here are two analogous groups, Group-I and Group-II, that list words in their decreasing order of intensity. Identify the missing word in Group-II.
