Based on the genetic variation, it is true that natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.
What is natural selection?
Natural selection is the process by which species which are better adapted to an environment survive over those not suited to the environment.
Does natural selection produce perfect adaptations?
Natural selection do not produce perfect adaptations because:
- Adaptations are often compromises.
- Organisms are locked into historical constraints.
- Selection can only edit variations that exist in a present population.
Therefore, it is true that natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.

Leaves are green because they contain chlorophyll, an agent that reacts with sunlight and allows plants to undergo photosynthesis, the process that allows plants to make food.

Answer:
The correct answer is a. Membrane budding requires transient breakages in the bilayer membrane.
Explanation:
In the budding process of the membrane there are no breakages because the lipid membrane is so flexible that they start making the new bud and don't have to add or quit any phospholipid, and then when the process is done lipids separate and the membrane comes to the original assembly and the new bud is formed.
Observing free‐living animals, performing experiments in the lab, doing theoretical research, and conducting fieldwork. Because a tradition by definition involves some sort of social learning, it is challenging, if not impossible, to determine whether a behavior is traditional without understanding how it is developing.
Free-living animal observations can offer compelling circumstantial evidence of a tradition. However, observation alone has not demonstrated adequate evidence to suggest that social learning contributes to the formation of behaviors of interest, even in the opinion of multiple researchers who have examined potentially traditional behaviors in wild populations.
The applicability of laboratory studies to the comprehension of how habits arise in free-living animals is always subject to debate. Even while they can generate intriguing theories, in-depth assessments of field data cannot test them. A potential direction is provided by field studies that examine how behaviors of interest manifest in population members.
