Answer:
The answer is true, the pumping of hydrogen ions decreases and finally stopps.
Explanation:
As the cyanide blocks the bindinge site for oxygen, which is normally reduced to water, the pumping of hydrogen from the matrix into the space between the mitochondrial membrane decreases and finally stopps. There is an accumulation of electrons and the components of the respiratory chain are completely reduced, therefore the respiratory chain stopps working.
Answer:
Tomatoes have a rich flavor, high water content, soft flesh which breaks down easily, and the right composition to thicken into a sauce when they are cooked (without the need of thickeners such as roux). All of these qualities make them ideal for simple and appealing sauces

Answer: D. downwelling
Downwelling is a oceanographic phenomena, in which the higher density material accumulates and sink below the low density water. The higher density sediments from the surface runoff sink down. The downwelling provides the supply of oxygen to the lower water layers along with the minerals present in the sediments. This allows the aerobic organisms to survive underwater. Therefore, Pedro should read the phenomena of downwelling to understand the fact that how aerobic organisms survive under water.
Answer:
a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures
Explanation:
This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
For example, Galapagos finches are isolated from others by the ocean (geographic isolation). Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
