The answer is; a) they are naturally occurring.
What does this mean for us? Water's polarity allows it to dissolve other polar substances<span> very easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa.

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 genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
- The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
- The genotype of a tree that is heterozygous for both trait would be BbTt
- Thus, the cross would be bbTT x BbTt
