Answer: Option C) They would not need to be transported through the body.
Explanation:
Red blood cells are a type of blood cell that have a biconcave disc shape and lack nucleus. They are transported around the body where they distribute oxygen.
Neurons, on the other hand, are a type of cell in the nervous system. They are of different types and are interconnected to one another such that they do not need to be transported at all while they transmit impulses around the body.
Thus, if red blood cells were shaped like the interconnected neurons, there would be no need for them to be transported through the body.
Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
Since living organisms require energy and both survival and reproduction... the sun provides the energy for photosynthesis. Cells need sugar as a sources of energy. The cellular respiration is the synthesis of ATP using energy that is being released by the breakdown of sugar to carbon dioxide and water.
Answer:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
