The correct answer is Manganese (Mn).
<span>Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. <span>Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.</span></span>
B. Decrease. The shrew population is dependent upon the grasshoppers as a prey item. A decrease in the available prey would result in a decrease in the predator population due to lack of resources to support the current population.
D) increases reproduction of native species
Explanation:
Non-invasive or non-native species or exotic species do not increase the reproduction rate of native species.
In fact, studies have shown that they reduce the rate of reproduction of the native ones.
- Invasive species where they are successful are huge threat to the stability of an ecosystem.
- Some invasive species are capable of destroying habitats by substituting for their functional roles.
- They compete with native species. In some cases, where an invasive specie is a predator, it preys on the native ones.
- Invasive species are capable of destroying the food source in an ecosystem.

Answer:
Letter B.
Explanation:
Aquaporins, also known as "water channels," are the main transport of water through the membranes of plant, animal, and bacterial cells. These channels allow the water to travel into and within cells and, at the same time, exclude the passage of ions and solutes.
What makes letter B the correct answer, is the form of transport and shape of the channel that allow water according to the osmotic gradient. In this model, letter A shows simple diffusion, while C and D seem to illustrate gated channels.
