Question

explain the relationship between the environment, variation, and selection.
changing ▼ can cause certain traits to be favored through ▼.
this can le ▼.
natural selection
environmental factors
genetic variation

Explanation:

To solve this, we analyze the context of evolution and natural selection:

1. The first blank is about what changes. Environmental factors (like climate, resources) change, so "environmental factors" fits here.
2. The second blank is about the process that favors traits. Natural selection is the process where favorable traits are selected, so "natural selection" goes here.
3. The third blank relates to the result of selection acting on variation. Genetic variation provides the raw material for selection, and selection can lead to changes in genetic variation (or adaptation, but from the options, "genetic variation" in the sense of how selection acts on it). Wait, re - examining: The sentence structure is "Changing [X] can cause certain traits to be favored through [Y]. This can lead to [Z]."

• X: Environmental factors change (e.g., a new predator, climate shift).
• Y: Natural selection is the mechanism that favors traits (organisms with traits suited to new environment survive/reproduce).
• Z: Genetic variation can be affected (or adaptation, but from the dropdown, "genetic variation" in the context of how selection acts on existing variation or leads to changes in it). Wait, the dropdown options for the first blank (from the image) are "natural selection", "environmental factors", "genetic variation". So first blank: "environmental factors" (since the environment changes). Second blank: "natural selection" (the process that favors traits). Third blank: "genetic variation" (selection acts on genetic variation, and over time can lead to changes in genetic variation in the population).

Answer:

First dropdown: environmental factors; Second dropdown: natural selection; Third dropdown: genetic variation
