Since the diagram is not provided, let’s describe molecule movement along the cell membrane generally. Molecules may passively travel through the cell without energy, an example being oxygen molecules. However, larger and non-polar molecules struggle to cross the membrane easily. These particular molecules will need energy to be transported through the membrane and may do so with the aid of carrier or facilitated proteins, such as glucose molecules.

A change in membrane permeability or ion concentration will change the resting membrane potential.
s2008m [1679]
It is correct <span>that alterations in membrane permeability or ion concentration can affect the resting membrane potential. The resting membrane potential is defined by the voltage across the membrane of a neuron at rest. This potential is influenced by the concentration gradients of ions such as Na+ and K+ and by how permeable the membrane is to these ions. In a resting neuron, there exist concentration gradients for Na+ and K+ ions across the membrane. Ions traverse their gradients through channels, which results in a charge separation that establishes the resting potential.</span>

Australia and New Zealand have a wide array of plants and animals found nowhere else because those organisms evolved in _____. Q
inysia [1663]
These organisms developed exclusively within these nations. They evolved in Australia and New Zealand due to the isolation of these countries, which prevents the introduction of crops or animals from other areas. A significant ocean barrier separates these regions from others, resulting in a unique evolutionary process.
