Question

according to the ihub chemistry materials, what do scientists specifically look for in outer space when trying to find life, and how do they detect it? a they look for molecules in outer space because molecules give off energy that scientists can detect. b they look for signs of intelligent communication and detect radio signals. c they look for large celestial bodies and detect them with powerful telescopes. question 4 (1 point) lesson 1 introduces a \driving question board.\ what is the driving question presented that helps guide what students need to figure out for the unit? a what do we need to know to figure out what substances would life out there be made of? b what are the ethical implications of discovering extraterrestrial life? c how can we develop faster spacecraft for interstellar travel? d how do different cultures perceive the existence of life beyond earth? question 5 (1 point) lesson 1 encourages you to consider if life beyond earth would be made of the samestuff as life on earth. true

Explanation:

1. For the first question, molecules can be indicators of life - related processes as they may give off detectable energy. This is a common approach in the search for life in space.
2. For the second question, when discussing life in the universe, a fundamental question is what substances life might be made of, which guides the exploration of life - beyond - Earth.
3. For the third question, Lesson 1's focus on life - beyond - Earth's composition implies considering if it's made of the same substances as Earth life.

Answer:

Question 3: a. They look for molecules in outer space because molecules give off energy that scientists can detect.
Question 4: a. What do we need to know to figure out what substances would life 'out there' be made of?
Question 5: True
