Hello there!
Part 1: At location 1, what is happening is the combustion of fossil fuels in factories and power plants to produce carbon dioxide (CO₂), which enters the atmosphere in the Carbon Cycle. This process started on a widespread scale in the Industrial Revolution with the invention of the steam machine. The reaction for the combustion of carbon is shown below:
C+O₂ → CO₂
Part 2: At this location, different types of energy transformation are happening successively. Considering that this is a power plant, firstly the potential chemical energy in the coal is transformed into thermal energy, this thermal energy is then transformed into mechanical energy by the action of the steam, and lastly, the mechanical energy is transformed into electrical energy in the generator.
Part 3: This process is a recycling of carbon in the carbon cycle because carbon that is transformed in this cycle eventually goes to carbon sinks (Fossil Fuels are carbon sinks). These carbon sinks sequestrate carbon and to return it to the atmosphere and recycling this carbon it is necessary to burn them in these factories. Thus, this is a recycling process in the carbon cycle.
Have a nice day!
Answer:
the cell membrane is very selective
cell Membrane is a very protective layersurrounding a ccell
Answer
Gas exchange is the delivery of oxygen from the lungs to the bloodstream
Explanation:
It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
write it in your own words, also can i have brainliest
Answer:
Diffusion is a passive process involving the movement of molecules from a region of a higher concentration to one of a lower concentration (the term passive means that the process does not require an input of energy to take place).
Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.
In animals:
Respiration - Oxygen and glucose react to form carbon dioxide and water along with ATP (a source of energy) in the process of aerobic respiration. Therefore, oxygen and glucose must be taken up by the cell, and typically the concentration of these molecules outside the cell is greater than inside. Therefore, the overall net movement of these molecules will be down the concentration gradient, and they will move into the cell via diffusion. Similarly, the carbon dioxide produced is a waste product and moves out of the cell, again via diffusion down its concentration gradient.
In Plants:
Mineral uptake - Useful minerals and ions need to be taken up from soil into plants via root hair cells. These cells are adapted (through a large surface area and large number) to maximise the rate of diffusion. Therefore, the useful molecules in the soil move down a concentration gradient and into the roots to be taken up by the plant. Many molecules found in the soil are essential for the growth and survival of plants, making diffusion a very important process.
