Explanation:
The color of a planet provides clues to its composition. From space, much of Earth looks blue because most of its surface is covered with water. The surface of Mars is much different from that of Earth. Much of its surface is made up of iron oxide, or "rust." Which color would you expect Mars to be?
Answer:
Mars would have different variations of brown, red, and orange.
Explanation:
Since different places of Mars have different substances or have different "ages" the color will be different.
Rust is formed because iron reacts to different substances, so there might be different weather patterns around Mars, and hence different colors of the rocks, iron, etc.

NASA believes that technology drives exploration. This means that advancements in technology lead to advancements in space exploration. Over the past 60 years, we have developed technology to leave Earth's surface, orbit the planet, reach the Moon, take exceptional pictures of celestial objects, and complete remote fly-by's of outer planets. In the future, technology could lead us to visiting other planets, live and work in deep-space, or even leaving our own galaxy.
Select the statement(s) that illustrate why developing space technology is important.
Technology in space helps us in our everyday lives here on Earth.
Space exploration technology has helped us explore the Moon and see images of far off galaxies.
Technology allows us to better understand our world so that we can make it better.
Technology only helps scientists while they are doing experiments.
Space technology may help us inhabit another planet or live in space in the future.

sound waves.
Hard materials such as brick walls tend to block sound waves while soft materials such as a thick carpet tend to absorb sound waves.
What are sound waves?A sound wave is defined as the pattern of disturbance which is caused by the movement of energy traveling through a medium as it propagates away from the source of the sound.
Sound waves are created by object's vibrations and produce pressure waves, for example, a ringing cellphone. The pressure wave disturbs the particles present in the surrounding medium, and those particles disturb others present next to them, and so on.
The pattern of the disturbance creates outward movement in a wave pattern, like sea water in the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source.

Answer: ok ?
Explanation:
What is the relationship between guard cells and stomata in plants?
Guard cells open and close the stomata to regulate the rate of transpiration.
Guard cells protect the stomata from insects and other pests.
Guard cells store carbon dioxide for later use by the stomata.
Guard cells absorb light energy from the Sun for use by the stomata.
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis . Critical in this process is the stoma.
Answer:
Guard cells open and close the stomata to regulate the rate of transpiration.
