Pollution, according to a UN report , are Dhaka (Bangladesh), Moradabad (India), Islamabad (Pakistan), Rajshahi (Bangladesh), Ho Chi Minh City (Vietnam), Ibadan (Nigeria), Kupondole (Nepal), Algeria . The noise level in these cities exceeds 100 dB. The Verge correspondent tested the Dyson Zone headphones in New York, where the noise level, according to the UN, is 95 dB. He commented that People often think of plants as the simplest forms of life that get fixed in one place and never develop again. A group of European scientists debunked this myth Interaction with the environment The researchers call plants "specialists who use everything that is near their place of existence." For example, many plants respond to changes in the length of the day.
Understand" when to start flowering. Researching such subtleties offers hope Russia WhatsApp Number List that humans will be able to grow crops in the future as climate change makes the weather more extreme, scientists say . 2022 discovered exactly how plant roots change their shape to maximize water absorption. They usually branch horizontally. However, this process is suspended if contact with water is lost. Roots resume branching only after they reconnect with moist soil. Scientists have attributed this process to hydrosignaling . Hydro signaling Hydrosignaling is a way for plants to sense where moisture is, without directly measuring its level. In this they are helped by molecules that move along with water inside plants through small pores.
When water enters the root of the plant, it passes through the outer cells. They contain a hormone that promotes branching - auxin . The absorption of water activates it. If its access is cut off, the roots have to rely on water from their own resources. This changes the direction of moisture movement, causing it to move outward, which disrupts the flow of auxin. Instead, another hormone begins to act. Stop branching Plants also produce a hormone that stops root branching, abscisin. It also moves along with the water flow, but in the opposite direction to the auxin.
