You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they
Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.  

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

stich3 [128]

Answer:

One method used by newborn mammals to generate heat is referred to as nonshivering thermogenesis. This method utilizes a protein channel called <u>thermogenin</u> which is present in high levels inside the mitochondria of <u>brown adipose tissue.</u>

Explanation:

Thermogenin forms a proton channel in the inner mitochondrial membrane in the brown adipose tissues. Most of the newborn mammals have these brown adipose tissues. In these tissues, the oxidation of nutrients do not produce ATP but generate heat. The heat is used by the newborn to maintain the warmer body temperature. The process is called nonshivering thermogenesis.

Explain why fertilizer use by farmers can have negative effects on aquatic ecosystems?
CaHeK987 [17]
The fertilizers used by farmers can have negative effects on aquatic ecosystems because there is every possibility that the runoffs from the fields can create an algal bloom in the nearby water body. This algal bloom can have a very negative effect on the living organisms of the aquatic body. I hope it helps.
