The correct response is a. Resting membrane potential (RMP). RMP describes the electrical potential difference across a cell membrane when the cell is not active. This difference arises due to the uneven distribution of ions such as Na⁺, K⁺, Cl⁻, and Ca²⁺ across the plasma membrane. It is influenced by the concentration gradients and the permeability of the membrane to these ions. The RMP value can vary by cell type; for example, a neuron's RMP is around -70 mV, whereas in skeletal muscle, it is about -90 mV. A negative value indicates a higher concentration of negative charges inside the cell compared to the outside.

The size of a grain refers to the individual diameter of a grain segment or a lithified particle in clastic rock (which contains fragments). On the other hand, grain texture relates to the feel, appearance, or consistency of a rock or any structure. The relationship between the increase in grain size and its texture depends on its composition; specifically, how size correlates with texture. However, the behavior remains independent in cyclic polycrystalline copper.
Answer:
Explanation:
The pH formula is given by
![pH = -[log H+]\\](https://tex.z-dn.net/?f=pH%20%3D%20-%5Blog%20H%2B%5D%5C%5C)
It's also stated that each pH unit indicates a tenfold change in hydrogen ion concentration.
For lemon juice with a pH of 2, the hydrogen ion concentration is
While for pure water, which has a pH of 
, the concentration is
Thus, the concentration of H+ ions in lemon juice is 
times greater than in pure water.
