Answer:
e.the ball exerts more force because it is smaller
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:
In metaphase ll, the chromosomes line up in the middle of the cell
Explanation:
The answer to this question would be: <span>by converting glucose to glycogen.
Brain cells only able to use energy from glucose, so if the body glucose level is too low the brain cells can't work as it doesn't get any energy/food. When glucose level is decreased, the liver will start to convert glycogen into glucose to keep the glucose level.</span>
<span>"One of the most common ways to control or eliminate pests is to use poisons that kill pests - pesticides."
