Answer:
A scientist discovers a new organism in run-off from the Rio Tinto River in Spain (the river runs through a copper mine and the water has a pH of 2.0). On basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. Given this information, this new species is most likely a <u>eukaryotic</u> cell in the <u>protozoan</u> subcategory
Explanation:
Eukaryotic cells contain nucleus and organelles and are enclosed by a plasma membrane. Organism that have these cells are protozoa, fungy, plants and animals.
Protozoan are single-celled eukaryotic.
The experiment demonstrated how some biological molecules, such as simple amino acids, could have arisen abiotically, under conditions similar to early Earth. Water, methane, ammonia and hydrogen were the chemicals used to produce the results of the experiment, therefore to produce similar results, one would have to have these chemicals present to initiate the reactions, this could lead to life arising on another planet
Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.
Explanation:
Binary fission and mitosis can be viewed as the same principle of asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.
Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles. Please give me the brainliest answer?
