Answer:
Un problema ambiental es un cambio que ha tenido lugar o se está produciendo en el medio ambiente que una persona encuentra problemático por alguna razón. Normalmente, solo los cambios provocados por el hombre se consideran problemas ambientales: los desastres naturales como terremotos o tormentas, por ejemplo, generalmente no se consideran problemas ambientales. Los problemas ambientales actuales a menudo se consideran relacionados, entre otras cosas, con el consumo excesivo y la superpoblación, el agotamiento de los recursos, la industrialización, la desigualdad y la pobreza, la ignorancia o la tecnología subdesarrollada.
Los fenómenos comunes considerados problemas ambientales incluyen el cambio climático, la eutrofización, el agotamiento del ozono, la erosión, la acidificación del suelo y el agua, la contaminación ambiental y el agotamiento de la biodiversidad, por ejemplo en forma de extinciones de especies.
Answer:
D). Tension decreases as children become more independent.
Explanation:
As per the question, the tension seems to decrease among most of the married couples after ten years of married life and the key reason is that the children become more independent and self-sufficient. <u>This helps in reducing the tension and stress of responsibilities for both the partners which further assists in lowering the chances of divorce and separation of them</u>.

Thus, <u>option D</u> is the correct answer.

The answer is: c. classical conditioning
In a classical conditioning, a certain behavior is learned by associating a certain stimulus with either positive or negative response.
For examples, let's say that every time the pets heard the sound electric can opener, the pets would immediately receive their food from their owners.
In the long run, the pets would associate the sound of the electric opener with the positive reward (in the form of food). This make the pets become most likely to experience biological response (such as watering mouth) every time they hear the electric opener.
