Question

1. ethan learned that astronomers use satellites to study different parts of the universe. which of the following statements describes how another scientist can use satellites?

a. a scientist can use satellites to study the composition of the earths core.
b. a scientist can use satellites to study the process of photosynthesis within cells.
c. due to the heavy tree cover, scientists can use satellites to study animal behavior in the amazon.
d. due to the inaccessibility and darkness of the polar regions, scientists can use satellites to collect climate data.

1. satellites are used mainly to gather light from astronomical objects. as they evolve, the telescopes mirror captures light and directs it into its various science instruments. how is this technology advancing our understanding of the universe?

a. it is capable of sending clear images of distant objects in order for scientists to study them.
b. it is capable of sending audio communication to other planets in our solar system for them to respond.
c. it is capable of counting individual atoms in a substance in order for scientists to study subatomic particles.
d. it is capable of collecting samples from other planetary systems in the universe in order for scientists to study them.

1. when studying celestial bodies, scientists use different waves within the electromagnetic spectrum. how does using different types of electromagnetic waves provide a more complete understanding of the celestial bodies?

a. em waves have the same energy, which provides unique information.
b. em waves travel at different speeds, which provides unique information.
c. em waves travel the same distance, which provides unique information.
d. em waves have different wavelengths, which provide unique information.

1. when using satellites, meteorologists noticed that visible light would get blocked by clouds. but electromagnetic waves with longer wavelengths could be detected. what type of sensor should meteorologists use?

a. sensors that detect x - rays.
b. sensors that detect gamma rays.
c. sensors that detect infrared waves.
d. sensors that detect ultraviolet waves.

Explanation:

1. Los satélites se pueden utilizar para recopilar datos climáticos en regiones polares difíciles de acceder. Las otras opciones son incorrectas: el estudio de la composición de los océanos (A) no es un uso común de satélites para este fin, el estudio de la homeostasis en células (B) no se hace con satélites y el estudio de conductas animales en la Amazonía a través de satélites es difícil debido a la cubierta vegetal densa y no es un uso principal de los satélites.
2. Los satélites astronómicos capturan luz de objetos celestes y envían imágenes claras a la Tierra para su estudio. No son capaces de enviar comunicaciones auditivas a otros planetas (B), contar átomos individuales (C) o obtener muestras de otros sistemas planetarios (D).
3. Las ondas electromagnéticas tienen diferentes longitudes de onda, y cada una proporciona información única sobre los objetos celestes. Tienen diferentes energías y velocidades dependiendo de la longitud de onda y no viajan la misma distancia necesariamente.
4. Las ondas infrarrojas tienen longitudes de onda más largas que la luz visible y pueden穿透 nubes. Las ondas X (A) y rayos gama (B) son de alta energía y no son las adecuadas para este uso, y las ondas ultravioletas (D) tienen longitudes de onda más cortas que la luz visible y también se bloquearían.

Answer:

1. D. Due to the inaccessibility and darkness of the polar regions, scientists can use satellites to collect climate data.
2. A. It is capable of sending clear images of distant objects in order for scientists to study them.
3. D. EM waves have different wavelengths, which provide unique information.
4. C. Sensors that detect infrared waves
