The sole of a gecko's foot is covered with millions and millions of small, dry "hairs" that make direct contact with surfaces, a
tamaranim1 [39]

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.

storchak [24]

Answer:

Lactose intolerance is when your body can't break down or digest lactose. Lactose is a sugar found in milk and milk products. Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase. Lactase breaks down the lactose in food so your body can absorb it.

Without a cuticle, a plant _____.
kolbaska11 [484]
The answer is A. The cuticle is a protective film that is non cellular covering the outer cell layer (epidermis) of green, aerial parts of plants. Cuticles protect plants against drying (desiccation), UV radiation, and various kinds of physical, chemical and (micro)biological agents. The cuticle also provides some support. Actually the cuticle which protects the underlying tissues has basically the same function as our own skin. In several groups of plants, cuticles are very resistant. Only few groups do not generally have highly resistant cuticles e.g. ferns and lycopods.
