Why Grades does this consistently occur?* Members O Small fragments have less charge on them and therefore travel farther. Conferences Small fragments are the first to leave the well and have more time to travel than the DBQ Online larger fragments. Jewsela O The higher molecular weight of larger fragments make them sink. mation O Small fragments move more freely through the agar gel. logy Periods 1 and 2 s periods nool MP1, HighschoolClassifiation of Llfe A new organism was discovered in a deep sea vent at the bottom of the ocean. The researchers collected the sample and made careful observations of it. The picture at right shows a microscopic image captured at 1000X its actual size. Below are some other observations made: • When DNA was isolated from the cell, it was mixed with an equal portion of histone proteins • There are no visible organelles present inside the cell • The specimen seem to die in the presence of oxygen • Able to live in conditions that mimic deep sea vents without any external food source provided Based on these observations, determine each of the following and provide a clear rationale. A) To which domain would you assign this organism? Why? B) Propose a hypothesis of how they obtain nutrients. Are these most likely autotrophs or heterotrophs? Provide a rationale.
