What is the physical basis of Phototropic response? What is the physical basis of the phototropic response? Cell elongation. How is the structure of a phytochrome related to its function? Structure. Phytochromes consist of a protein, covalently linked to a light-sensing bilin chromophore. Together, these subunits form the phytochrome region, which regulates physiological changes in […]

What type of vegetation should you expect to find on newly formed volcanic islands? On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not […]

Which pressure system in the southern hemisphere rotates counterclockwise? The coriolis force caused by the Earth’s rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the […]

Which toes does the long extensor muscle control? The extensor hallucis longus muscle extends the foot’s big toe. What muscles control the toes?
