It’s either A or B. I would probably say A because, In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter using the oxidation of inorganic compounds or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse. Groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria. Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites where hydrogen molecules are available, the energy available from the reaction between CO₂ and H₂ can be large enough to drive the production of biomass.
The most abundant element in the human body is oxygen
I think the best way to answer it is by the use of Binomial nomecleture that is used as a formal naming of species of living things by giving each name by two parts, Latin grammatical form and the Binomial names. I hope you are satisfied with my answer and feel free to ask for more
May have once had liquid water, has a reddish color from iron, is a terrestrial planet,
Ok, I'm not 100% sure this is correct, given the context of the situation, but basically, the cell membrane helps the cell maintain homeostasis by keeping what needs to be in in & what needs to be out out. If it weren't for the cell membrane having the structure it does, all kinds of things could get into the cell & completely kill it from filling it with too much stuff, or the wrong things could get in (say, things with a really odd pH) & damage it badly. Or, it could let things get out extremely easily, such as enzymes and ions the cell needs to function properly.
Hope this helps!
