How do antispasmodics work? What conditions are they used to treat? How do Tetrahymena move? What effect does ouabain have on tonicity? Explain Gravitropism. What is immunohistochemistry and what is it used for? How are tRNAs charged?
Plants exhibit tropisms, tendencies to grow in certain ways based on environmental factors, such as sunlight (phototropism), water (hydrotropism), gravity (gravitropism), chemicals (chemotropism) and even physical contact (thigmotropism). For example, plants tend to bend toward sunlight because sunli...
Imagine that lightning hits a tree, which causes it to fall and hit a young sapling. The young tree is now bent over towards the ground. Discuss how gravitropism will affect the plant so that it will still be able to survive. Clearly explain the adaptations that p...
Earth is one of the inner planets of the Solar System, but – unlike the others – it has an oxidising atmosphere, relatively stable temperature, and a constant geomagnetic field (GMF). The GMF does not only protect life on Earth against the solar wind and cosmic rays, but it also shiel...
