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: The Shape of Molecules
The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. In order to represent such configurations on a two-dimensional surface (paper, blackboard or screen), we often use perspective drawings in which the direction of a bond is specified by the line connecting the bonded atoms. In most cases the focus of configuration is a carbon atom so the lines specifying bond directions will originate there. As defined in the diagram on the right, a simple straight line represents a bond lying approximately in the surface plane. The two bonds to substituents A in the structure on the left are of this kind. A wedge shaped bond is directed in front of this plane (thick end toward the viewer), as shown by the bond to substituent B; and a hatched bond is directed in back of the plane (away from the viewer), as shown by the bond to substituent D. Some texts and other sources may use a dashed bond in the same manner as we have defined the hatched bond, but this can be confusing because the dashed bond is often used to represent a partial bond (i.e. a covalent bond that is partially formed or partially broken). The following examples make use of this notation, and also illustrate the importance of including non-bonding valence shell electron pairs (colored blue) when viewing such configurations .
Methane Ammonia Water
Bonding configurations are readily predicted by valence-shell electron-pair repulsion theory, commonly referred to as VSEPR in most introductory chemistry texts. This simple model is based on the fact that electrons repel each other, and that it is reasonable to expect that the bonds and non-bonding valence electron pairs associated with a given atom will prefer to be as far apart as possible. The bonding configurations of carbon are easy to remember, since there are only three categories.

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.

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.
Answers
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.

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?
Answers
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.
