I believe those are both non-contact forces bc it's not something physical
The main difference between a plant cell and the animal cell is the presence of cell wall.
In the plant cell, the cell wall is present, but in the animal cell, the cell wall is absent.
Hence, in the onion cells, the cell wall around the cell would be clearly visible, whereas in the case of cheek cell, the cell would only be lined by a cell membrane, a cell wall would not be present.
Further, the plant cell would have the chloroplast, as they perform photosynthesis, but the animal cell would not have chloroplast. Unlike animal cell, the central vacuole in the plant cell is bigger and clearly visible.
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
Biological Weathering<span>Biological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things called </span>lichens<span> (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler. </span>
