In another context, talking to flowers in general help because when you breathe out Carbon Dioxide, flowers and plants absorb it as it is what they need to grow.
Answer:
<u>Depending upon the mass of various bodies and the gap between them, such as planets, satellites, etc., there appears a pulling effect between these massive masses. This pulling effect is known as gravitational force. One can establish the relationship of the orbital period by equating the gravitational force with centripetal force and substituting the velocity relation with the period.</u>

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.
The palisade mesophyll has long cylinder shaped cells, lots of chloroplasts, cells closely packed together and large size of cells.
