Are models used in science? Models have always been important in science and continue to be used to test hypotheses and predict information. Often they are not accurate because the scientists may not have all the data. It is important that scientists test their models and be willing to improve them as new data comes […]

What are the three properties of hydrogen bonds? Cohesion and adhesion of water: Water can stick to itself (cohesion) and other molecules (adhesion). Specific heat, heat of vaporization, and density of water: Water has a high heat capacity and heat of vaporization, and ice—solid water—is less dense than liquid water. What are the properties of […]

Are all Animalia autotrophic? All animals and fungi are heterotrophs. Autotrophs, on the other hand, that create their own food by fixing carbon. In other words, autotrophs get their carbon directly from carbon dioxide, which they use to create organic carbon compounds for use in their own cells. Are all Animalia heterotrophic? All members of […]

How are spores different from seeds? The main difference between spores and seeds as dispersal units is that spores are unicellular, the first cell of a gametophyte, while seeds contain within them a developing embryo (the multicellular sporophyte of the next generation), produced by the fusion of the male gamete of the pollen tube with […]
