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.
4) digestive and circulatory, because the bladder is part of the digestive system. The circulatory system carries blood around the body using blood vessels.
1. Nucleus step1: DNA is transcribed into mRNA
2. Ribosome step2: mRNA is translated into protein
3. Endoplasmic Reticulum step 3: Newly synthesised proteins are transported.
4. Golgi apparatus Step 4: Proteins are modified then transported away
In Golgi body or apparatus, the proteins are modified, sorted and packaging occurs for secretion.
