All of these are not part of the life cycle. It's man-made. Think of it in biology terms - something that's created genetically.
<span>Interstitial diffusion occurs more rapidly in metal alloys because these atoms are smaller, and therefore they are more able to move and vibrate as compared to atoms that are larger and less able to migrate.</span>
The answer is A: '<span>underwater landslides </span>'. Underwater landslides would cause a wave, rather than a current. Ocean waves are caused by energy passing through water. An ocean current on the other hand is a mass of water moving in a definite direction through another mass of water. This movement is driven by forces that could be derived from surface winds, tidal fluctuations and seawater density contrasts.
Eukarya. This is because their cells all have a nucleus. While prokaryotes like archaea and bacteria don't have one, eukarya have a nucleus.
