Junipers, hemlocks, and cedars belong to the conifer group.
This process is called as imprinting. It occurs at a particular stage of life and is, therefore, a phase-sensitive learning process. It can be of many types, including filial imprinting, where an offspring gains some of its behavioral characteristics from the parent, or sexual imprinting, through which desirable characteristics of a mate are recognized by a young animal.

Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
