Sound and light are both found as (4)
Mrrafil [7]

Answer:  

Waves; wavelength; electromagnetic energy; ultraviolet light.  

Explanation:  

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.  

Sound travels faster through solids than it does through either liquids or gases.  

Lightwave can be defined as an electromagnetic wave that does not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Hence, sound and light are both found as waves, with a variety of wavelengths. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of which can be harmful.

Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB ,and UVC.

Which biome has leaves that change color and fall off as winter approaches?
Galina-37 [17]

Answer:

Option (A)

Explanation:

The temperate forest usually covers the tropical and the taiga region. The trees in this forest region experience all the four seasons namely summer, autumn, winter and spring. It comprises approximately 25% of the total forest-covered region on earth. The leaves of these trees change color during the autumn season, which eventually falls off during the winter season, and again, new leaves grow back during the spring season. This enables the plants to survive and go through the cold temperature in the winter.

Thus, the correct answer is option (A).

when gas evolution becomes very slow, heat the solution gently in the hood, then allow it to cool. What gas is formed in this re
son4ous [18]

Nitrogen gas is formed in this reaction.

<h3 /><h3>Nitrogen gas</h3>

Atomic number 7 and the letter N designate nitrogen as the chemical element. Group 15 of the periodic table, often known as the pnictogens, contains nitrogen as the lightest nonmetal element. It ranks eighth in overall abundance in the Milky Way and the Solar System, making it a common element in the cosmos. Two of the element's atoms combine to create the colorless and odorless diatomic gas N2 at standard temperature and pressure. The most common element that isn't mixed, N2 makes up around 78 percent of the Earth's atmosphere. All living things contain nitrogen, which is mostly found in amino acids (and thus proteins), nucleic acids (DNA and RNA), and the energy-transfer molecule adenosine triphosphate.
