The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.

What is Mutualism?

A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.

A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.

Therefore, the correct option is B.

B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.

Answers

Answer:

C) the sun's rays that fall on the moon's surface.

Explanation:

The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

Moving a book to a lower shelf decreases potential energy.
True
False

Answers

Answer:

True

Explanation:

Moving a book so the potential energy of the system decreases is a true statement.

What is potential energy?

A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.

A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.

Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.

Therefore moving the book to a lower shell change potential energy, which decreases.

Briefly describe the relationship between hormones, emotion, and external behavior

Answers

Hormones appear to be influenced by emotion and external behavior. For example, one's activity level may increase the production of a hormone, just as hormones often influence the way an individual feels. Hormones are found to impact behavior indirectly through emotional experiences. For example, an individual may feel a specific way as a result of hormone fluctuations but not behave or act out accordingly. The interaction between the emotion and environment play a large role on how hormonal influences are expressed behaviorally. Hormone production also appears to influence various behaviors.
