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:coconut oil, butter, palm oil, olive oil, canola oil.
Explanation: .
A saturated fat one whose fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules which are glycerol and fatty acids. Fats are made of long chains of carbon (C) atoms while some carbon atoms are linked by single bonds (-C-C-) bonds others are linked by double bonds (-C=C-). These Double bonds will react with hydrogen to form single bonds causing them to be SATURATED, because when the second bond is broken, each half of the bond is then saturated with a hydrogen atom.
In terms of saturated fats acids composition by percentage according to ChartsBin statistics collector team 2011, Fat Composition in different Cooking Oils, ChartsBin.com, palm oil is 14.192, coconut oil is 91.92 canola is 7.46,palm oil 51.57, butter 65%-68%.Here you can see that the order of saturated fats from the highest gives- Coconut,butter, palm oil,olive oil and Canola as the last

Sample Response: The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard and trillium. One was left open to deer, and the other was fenced off. Scientists kept track of the fields for several years. They found that trillium was able to regain much of its original space in the protected field. In the unprotected field, there was still more garlic mustard because the deer ate the trillium. The author also states that similar research studies have been conducted in many forests across the United States, and they all reveal similar results.
