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.
Answer:
These organisms should be adapted to live in this enviroment, i.e., they need to have adaptations to breathe, to swim (fins), streamlined bodies to move through the water, to eat the food found in the region, etc. Moreover, in this environment, the diversity tends to be high because marine regions are often characterized by their richness.
Yes I believe the answer is D it is th only logical one.
The answer is four bonds because they can use one electron for each bond.
Hope that helped :)
The correct option is D.
If water density at freezing point is greater, the ice formed will sink to the bottom of the water body and freeze the water up from the bottom. This will surely lead to the death of everything that live inside the water.
