Answer: b dead organisms And waste are recycled throughout the tropic levels.
Explanation:
Answer:
The sediment is thin near spreading ridges, and thicker away from the ridges.
Explanation:
Marine sediments are insoluble particles of rocks, soils, volcanoes, chemical and organic bodies that are carried from land to the ocean through streams and lakes. The particles are usually of different sizes, which are found either on the shores of the oceans or on the seabed in the form of small rocks and gravel. As stated in the question, in most places currents do not move the sediment very much so that it remains where it falls. However due to the constant movement of the current near the ridges, the sediments are constantly dragged, leaving a thin layer of sediment in this region. On the other hand, the sediment layer is thicker in the ridges region, because the current movement is less constant.
Answer:
2,787

Currently there are over 2,787 active artificial satellites orbiting the Earth.
Answer: performs most metabolic functions of the body
Explanation:
1.it produces proteins with the help of vitamin and therefore helps in blood clotting
2.it breaks down old and damaged blood cells
3.it causes break down of fats and produces energy which is utilized by the body hence it helps in fat metabolism
4.it produces bile and causes excretion of bilirubin ,cholesterol,hormones and drugs.
5.it metabolises proteins and carbohydrates
Answer:
Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.
Explanation:
The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.
