Answer:
C.
Explanation:
Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.
The appropriate answer is b. turgor pressure. Turgor pressure is also known as hydrostatic pressure and is the force of the water inside the cell of the plant that pushes the cell membrane against the cell wall. When this force is strong the cell or the plant is said to be turgid. This pressure is maintained by the process of osmosis.
Plants react differently to the stimulus of light. They will grow or turn leaves towards light.
Gametes are produced in meiosis, they are a sperm or egg that is fused together with another gamete to make a zygote.
Answer:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Weathering and erosion constantly change the rocky landscape of Earth.
