the answer is the first one: by producing random changes in an organism's genetic code
Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem
Nerve cells, also called neurons, are specialized cells for the nervous system that is responsible for movement and response system. This is done through action potentials that lets the neurons generate a electric synapse to that received stimuli.
When there is an unequal amount of charges between the sides of the neurons, this can be described as diffusion potential or the resting potential.
Answer:
These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection.
