Energy is started from the sun, with 100 percent of the energy given to plants. when the plants are eaten, only 10% of that energy is given to the animal, like a rabbit. When the rabbit is eaten by a larger predator, only 10% is given of the rabbits energy. This continues, so to find the amount of energy within a certain organism you would need to calculate 10% from each original source of energy
Answer:
The world needs to stop the use of Plastic Water bottles.
Because plastic is non-biodegradable, it pollutes the environment, the rivers, drainage systems, and even our oceans.
Plastic Water Bottles have become a bio-hazard to our marine ecosystem. Autopsies performed on some sea fish have revealed several kilograms of human waste comprising mostly of plastic.
Another reason why it is critical to commence the disuse of the plastic water bottle is that it is not sustainable. Plastic is made from resins. Resins are gotten from plants and trees. It is impossible to continue to harvest resins at the current rate of plastic production and still have a green earth.
In some countries, purchasing water in a plastic bottle is a status symbol. The politicians who need to make decisions with regard to these issues are not helping matters because many of them either are not concerned or have vested interests in the companies along the value chain of plastic water bottle production.
Economically speaking, discontinuing the production of plastic water bottle may hurt quite a few companies. However, the government can help them transition into the production of other types of bottles such as stainless steel or glass water bottles which have less hazardous effects on the environment.
Cheers!
Answer:
The CFTR behaves like a channel for chlorine. Its dysfunction affects both the transport of this ion and other ions and the transport of water, which causes a thickening of secretions, an alteration of mucociliary transport and local defenses, facilitating bacterial colonization and promoting the release of pro-inflammatory mediators in the airway
Explanation:
CFTR is a protein expressed in the epithelial cells of the respiratory system, pancreas, bile ducts, sweat glands and genitourinary system. It is made up of a single chain made up of 1,480 amino acids. It contains 12 hydrophobic regions embedded in the lipid membrane and acts as a channel for chlorine.The highest levels of expression of the CFTR protein are found in serous cells of the submucosal glands of the proximal airway. In them, Cl- is released to the outside. In addition, there are channels for Na +, through which this ion is also secreted in the same direction. These movements cause the displacement of water and also of mucins, originating in the submucosal glands, allowing their presence on the surface of the airway. For all this to occur normally, a basolateral Na + - K + - ATPase cotransporter must function, another basolateral cotransporter formed by Na +, K + and 2 Cl-, which allows the latter to enter the cell, and an apical CFTR channel through which it exits the Cl- of the cell towards the acinar lumen. Na + leaves the cell following Cl- by a paracellular pathway accompanied by water. When CFTR malfunctions, Cl- does not exit through this channel and this implies a decrease in Na + and water in the canalicular lumen, with the consequent thickening of secretions.
