Answer:
The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange. If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.
An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population
Explanation:
That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.
Anyway, goodluck.

Nature does = environmental stress or changes
Answer:
La vejiga natatoria en un pez, se ve afectada por la presión hidrostatica del agua, generando presión y estrechamiento sobre esta, al disminuirse hace más fácil la inmersión, puesto que está vejiga contiene aire que tiene peso menor que el agua y hace flotar con más facilidad al pez, sin embargo cuando el pez sube, la vejiga aumentará su volumen y tendrá que nadar más para mantenerse más abajo en el agua
Answer:
Precipitation is rain, snow, sleet, or hail — any kind of weather condition where something's falling from the sky. Precipitation has to do with things falling down, and not just from the sky. It's also what happens in chemical reactions when a solid settles to the bottom of a solution.
Explanation:
Answer: Water evaporates from the Earth's surface and rises on warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow.
Explanation: I hope this helps!
