LEARNING OPPORTUNITY 3 A DIRECTIONS: Read the passage and answer the questions that follow Our bodies are adapted to Earth's gravity. Our muscles are strong in order to overcome gravity as we walk and run. Our inner cars use gravity to keep us upright. And because gravity wants to pull all our blood down into our legs, our hearts are designed to pump hard to get blood up to our brains. In space, the much weaker gravity makes the human body change in many unexpected ways. In microgravity, your blood is rerouted, flowing from the legs, which become thin and sticklike, to the head, which swells up. The extra liquid in your head makes you feel ike you're hanging upside down or have a stuffed-up nose. from "Life Without Gravity" by Robert Zimmerman 1. What is the main idea of the passage? 2.

Answer:
"Life Without Gravity" by Robert Zimmerman
Explanation:
1. What is the main idea of the passage?
The passage tackles about how the body or the whole human biology work with the Earth’s gravity. It describes and illustrates how the physiology and anatomy will be affected if there’s no gravity. The descriptions are usually abnormal.
2. Name two details that support the main idea
The details such as “Our muscles are strong in order to overcome gravity as we walk and run” and “our hearts are designed to pump hard to get blood up to our brains” supports the idea.
3 Write a brief summary of the passage on the lines provided.
Human bodies cannot adapt in planets where gravity is either weak or does not exist. Human beings’ anatomy and physiology are not dependent but they adapt to the gravity. If gravity is absent, the transport of blood and other bodily liquids might not be delivered to where it should be like blood or liquid in the head.
