The main function of sugars in living organisms is to supply energy.
I believe the first option should be 2, and for the second options, number 2 is right.
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>
Response: a) true
Clarification: The liquid within the egg plays a critical role in ensuring the embryo's survival and providing a fluid medium necessary for its development.
