Upwelling is a process in which cold water from depths arise to the surface
Answer:
This means that the means height (which is all the sum of the height of all the students divided by their number ) is 205 cm. Standard deviation means how the height of the students deviates from this mean since students do vary in height and are not all the same height of 205 cm. Therefore, in this case, the amount of standard dispersion of the students' height is by 17 cm on either lower or higher side of the mean.
Answer: D. Acid from abandoned mines
Explanation:
Point source pollution can be define as the pollution that can be caused by a pollutant whose source of origin is known. As the source of origin is known the path of the pollutant can be traced back to it's origin hence, the pollution can be controlled.
Among the options given, D. Acid from abandoned mines. is the correct option this is because of the fact that the source of origin of the pollutant is known that is abandoned mines.
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
Answer
Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.
Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric CO2 concentration. CO2 is constantly being absorbed by green plants maintaining its concentration through carbon cycle,Therefore massive deforestation which removes green plants, cutting down photosynthesis is one of human activities which raises CO2 levels of the atmosphere.The CO2 dissolves in the oceans to raise its acidic levels.Lower pH.
Another source is fossil fuels emissions which add more CO2 to the atmosphere.
