Anastaziya [24]

Answer:

thigmotropism

Explanation:

Tigmotropism is the curved growth of the plant, which occurs through mechanical stimulation. In the case of the question, the stone stimulated the plant's angular growth.

When the vegetable comes into contact with any consistent object, it grows around it. A very common example of tigmotropism is that of tendrils, which grow wrapped around its support. The winding occurs by a reaction that results from a stimulus from the underside of the tendril, this reaction slows the growth of this side, while the upper side grows faster.

Humans contribute to many changes of areas such as beaches, bays, wetlands, the sea floor, and coral reefs. How does the deliber
aleksandr82 [10.1K]
In many regions, wetlands have been filled in so as to be able to use the land for farming. Wetlands are vital for reducing the intensity of floods, as they tend to hold back some of the water. Without wetlands, flood will tend to wash increased sediment and pollutants into the ocean, which can have a detrimental effect on marine life. Coastal developments can also have a negative effect on marine life. The removal or moving of beach sand is in particular damaging to intertidal organisms that depend on specific coastal environments, and rocky shores can be smothered by sand, whereas sand environments can change into bare rocky environments. Impounding of rivers and reduced river flow can result in estuaries becoming closed. Many marine organisms, such as fish, depend on estuaries as nursery areas where they lay their eggs. Reduced opening of estuaries means that many fish species cannot reproduce. Built harbours result in changed currents and alteration of the sea floor, which also disrupts marine ecosystems.
