List three characteristics of living organisms
Darwin reasoned that natural selection organisms had adapted to new environments, giving rise to new species. It is a principle of speciation.
<h3>Speciation, natural selection and environment</h3>
Different environmental pressures (e.g. the type of food) lead to different evolutionary pathways in genetically related organisms.
The organisms subject to different environments evolve as a consequence of natural selection in order to adapt (adjust) to their corresponding environments.
In consequence, this process may eventually lead to speciation due to the emergence of reproductive isolation barriers.

Survival of the fittest is talking about when you have traits that will help you, you are more likely to live rather than not having those traits. For example, a bird that swims a lot has webbed feet so it has a better chance of surviving then a bird who does not have webbed feet
Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.
Answer:
Explanation:
1. Depolarizes (depolarization of membrane causes opening of sodium channels which causes outward motion of emphatically charged sodium particles into the grid from the phones. This makes the network be profoundly positive charged and the cell film turns out to be exceptionally contrarily charged)
2. Sodium particles, ECF (As the layer depolarizes, the voltage gated sodium channels situated over the plasma membrane open up and the outwards motion of sodium particle happens deserting an enormous negative charge on plasma layer)
3. Invigorated (the muscle cells contain afferent and efferent neurons which help in transfer of data from muscles to mind and back to muscles. This progression of data happens by the methods for emission of synapses from the mind because of an upgrade)
4. Potassium particles, hyperpolarize (after the activity potential has been played out, the sodium particle channels near forestall further spillage of sodium particles in the ECF. Be that as it may, the potassium channels stay opened for longer occasions and consequently hyperpolarize the layer with a net profoundly negative charge)
5. Resting membrane potential (this procedure is known as transmission of motivation in a cell by a pattern of polarization, depolarization and hyperpolazation)
