Question

natural selection and evolution
have you ever wondered why giraffes have such long necks or why some birds can fly while others cannot? the answer lies in evolution and natural selection.
evolution is the process by which living things change over time. natural selection is one way evolution happens. it means that animals and plants with traits that help them survive are more likely to live and have babies. these helpful traits get passed on to the next generation.
let’s look at an example: the peppered moth. before the industrial revolution in england, most peppered moths were light - colored, which helped them blend in with the trees and avoid being eaten by birds. when factories started making a lot of pollution, the trees turned dark. now, dark - colored moths were harder to see, so they survived better. over time, more moths were dark - colored. this is natural selection in action!
natural selection works like this:

1. there is variation in traits (like color or size) among individuals in a species.
2. some traits help individuals survive and reproduce better than others.
3. those individuals pass their helpful traits to their offspring.
4. over many generations, these traits become more common.

evolution and natural selection help explain why living things are so well adapted to their environments. they also show us how species can change over time.

multiple answer 10 points
evolution helps explain
why there is so much variation in plant and animal life?
how much an organism can change in one generation.
why living things are well adapted to their environment.
why some species cannot reproduce with other species.

Explanation:

El texto trata sobre evolución y selección natural, que es un tema de Biología (subcampo de Ciencias Naturales). La pregunta es sobre qué explica la evolución. Según el texto, "Evolution and natural selection help explain why living things are so well adapted to their environments. They also show us how species can change over time." Entonces, la opción correcta es la que dice "Why living things are well adapted to their environment" (la segunda opción, la que está marcada con la flecha en la imagen, pero en las opciones, la que corresponde a "Why living things are well adapted to their environment").

Answer:

The option (the one with the arrow, which is the second checkbox option) : Why living things are well adapted to their environment
