create their own food using light source and photosynthesis process or through obtaining energy through oxidation. Some example of living organisms that is autotrophs that is not plants are red algae and cyanobacteria. • Plants do not need cellular respiration because they carry out photosynthesis Answer: False. Plants also undergo respiration like any other living organisms to generate ATP for endergonic reactions. • Chlorophyll is the only photosynthetic pigment. Answer: False. Chlorophyll

Common Ion Effect HA(aq) + H2O(l) ⇔ A−(aq) + H3O+(aq) • Adding a salt containing the anion NaA‚ which • is the conjugate base of the acid (the common ion)‚ shifts the position of equilibrium to the left This causes the pH to be higher than the pH of the acid solution 9lowering the H3O+ ion concentration

A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth‚ both living and extinct‚ have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive
