Answer:
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
Answer:
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Explanation:
Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.
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 answer to this question should be: <span>"i can return to my normal activities like cleaning my house and vacuuming"
A post cataract surgery patient will be prone to an airborne allergen such as dust so it is not recommended to do any cleaning or be in a place with much dust. Vacuuming will increase the amount of the dust in the room and this might cause damage to the patient eye.</span>
