Answer:
D
Explanation:
Lamark believed in the inheritance of acquired characteristics. That is, that if an individual's body or organs changed in some way during the course of their life time (due to the environment or some other pressure), that these characteristics could be passed on to the next generation.
This was his theory of evolution. Therefore, if, slowly elephants started using their trunks to an advantage more, they would start to develop and grow. Lamark believed these acquired traits would be passed on to the next generation. We now know this not to be true, and random, selectively advantageous mutations in DNA are what cause evolution over time.
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.

The dermis is the layer of the skin where the sweat glands which work to cool your body are found.
<h3>What are sweat glands?</h3>
Sweat glands are glands which produce sweat which is helps to cool the body when the body is hot.
The sweat glands are found in the middle layer of the skin known as dermis.
The other layers of skin are the epidermis found in the outermost layer and the hypodermis found in the deepest layer of the skin.
Therefore, the dermis is the layer of th skin where the sweat glands which work to cool your body are found.
