Your answer is going to be Hydrolysis
I think they are good and bad
Explanation:
Make a standard, "dart" design paper airplane
Fold your paper into the basic dart paper plane. Fold carefully and make your folds as sharp as possible, such as by running a thumbnail or a ruler along each fold to crease it. Do not bend up the edge of the wings
Throw the plane at least four more times. Each time before you throw the plane, make sure it is still in good condition (that the folds and points are still sharp). When you toss it, place your toe on the line and try to launch the plane with a similar amount of force, including gripping it at the same spot.
Once you have a good idea of how far your plane typically flies, change the plane’s shape to increase how much drag it experiences. To do this, cut slits that are about one inch long right where either wing meets the middle ridge. Fold up the cut section on both wings so that each now has a one-inch-wide section at the end of the wing that is folded up, at about a 90-degree angle from the rest of the wing.
Make paper planes that are different sizes and compare how well they fly.
Try making paper planes out of different types of paper, such as printer paper, construction paper and newspaper. Use the same design for each.
Some people like to add paper clips to their paper planes to make them fly better. Try adding a paper clip (or multiple paper clips) to different parts of your paper plane (such as the front, back, middle or wings) and then flying it

Answer:
Stabilizing selection
Explanation:
The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.
During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.
In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.
Thus, Stabilizing selection is correct.
