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.

b
Explanation:
The greatest amount of kinetic energy is at the lowest point of the roller coaster. The least amount of kinetic energy is at the highest point of the roller coaster
Transcription is initiated when the RNA Polymerase binds to promoter region and transcription is ended when RNA Polymerase binds to termination sequence.
Promoter consensus sequence is important as it is the ideal promoter sequence and is used to judge the promoter's strength. The consensus sequence can be different for different group.
Transcription is the process of forming mRNA from DNA for the purpose of protein synthesis. The initiation occurs when the polymerase binds the promoter and stops when binds the terminator sequence.
Promoter consensus sequence is a sequence that is ideal as promoter. It is a theoretical sequence and the sequence most close to it is considered to be better. We can find different consensus sequence.

Answer:
3. The equator receives more direct sunlight than the North Pole.
Explanation:
<h2>The equator is the longest latitude at 0°.</h2><h2>The equator isn't influenced any change when the earth revolves around the sun cause winter and summer. </h2><h2>That's why equator is warmer than north and south pole.</h2>
<h2>I hope you understood</h2>
