This is called the cell wall!
Answer:
<em>The function of the xylem is to transport water.</em>
Explanation:
Xylem can be described as a vascular tissue which transports water from the roots to other parts of the plant. Xylem cells form a long tube-like structure for the water to move. The mixture of water and some nutrients that pass through the xylem is known as a xylem sap.
On the contrary, phloem id the vascular tissue which is involved in the transportation of food from the leaves to other parts of the plant.
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, through a process called ocean acidification. Ocean acidification interferes with the ability of marine organisms (including corals, Dungeness crabs, and snails) to build their shells and skeletons.
exosphere is not involved in the watercycle.
Answer:
<em>The correct option is Karl Marx .</em>
Explanation:
Communism can be described as a type of socialism whose aim is to create a society which is free of any classes.
Karl Marx was of the view that poverty and diseases were endemic that could only be resolved when capitalism will be replaced by communism. As Karl Marx, himself, observed discrimination in his early life hence he fought all his life to make people believe in communism instead of capitalism. He even had to flee away from his hometown due to his views on communism.
