Answer:
e. All of the above are correct.
Explanation:
Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.
Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.
Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.
The cell is most likely a prokaryote
A type of cell with no nucleus
Answer:
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Explanation:
On the presented food web we can see a food web that is complex and typical for the African savanna. As in all food webs, one organism is important for the survival of another organism or for the survival of numerous organisms. In this case, we have the grasshopper and its importance in the ecosystem, and which animal will be the most affected if it suddenly was not in this ecosystem anymore.
The bird and the baboon both feed on grasshoppers, but there is one big difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well. This means that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving, and if it doesn't adapt quickly enough to feed on something else it will probably go extinct. The baboon, on the other hand, will be affected but not so dramatically as it will continue feeding on the other food sources, though it might suffer some smaller losses in its population.
The answer is Water cycle because that is what photosynthesis is
