The main reason for the increase in the population of the moose is decrease in the predation by wolves.
The wolves eat the mooses, and the presence of the wolves do not let the moose population increase, as the population of the wolves decrease, the predation of the mooses also decrease. As a result, more mosses can survive, which lead to the increase shown in the graph.
Answer:
They are opened either by the binding of ligands or by changes in electric potential across the membrane
Explanation:
Ion channels are the integral membrane proteins that form pores or holes for the transport of specific ions, such as potassium ions (K+), Na+, etc. Most ion channels are selective and allow only a single type of ion to pass through. These ion channels facilitate the diffusion of ions down the concentration gradient and do not require ATP.
Ion channels are mostly gated. Some ion channels open in response to change in the concentration of ions and electric charges across the membrane. Some ion channels open and close in response to the binding of specific molecules called a ligand. For example, binding of two molecules of acetylcholine to the receptor on the motor endplate of a neuromuscular junction opens an ion channel in the ACh receptor through which Na+ can flow across the membrane.
Based on your knowledge of the carbon cycle, what do you think might happen if humans were to continue to clear and burn vast areas of forests for building? Eventually we would run out of forests and the air would be very polluted. Explain how a nutrient can be a limiting factor in an ecosystem.
