Plants also have structures that help them survive. Plants have different parts, like roots, stems, leaves, flowers, and fruit. These structures help them survive. Other plants have flowers that are the perfect shape for insects to visit and help with pollination. Some plants have really long roots that help the plant gather water from deep below the surface of the Earth. Plants that live in really dry areas, like a desert, have special leaves.

Solar energy is more Natural since it comes from the sun and easier to harness, while chemical energy is Dangerous because it may fail and cause damage.
Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.
RNA contains the genetic code
