Answer:

A. It will slowly lose energy to the water around and become weaker the farther it goes

Explanation:

Speed of sound in a medium

c = √(K/ρ)

K is the elastic bulk modulus and ρ is the density

For water

K = 2.2 GPa

ρ = 997 kg/m³

c = √(2.2×10⁹/997)

c = 1485.46 m/s

For material of boat (say steel)

K = 167 GPa

ρ = 8050 kg/m³

c = √(167×10⁹/8050)

c = 4554.71 m/s

Here it can be seen the speed in solid is faster than in water so sound will lose energy when it passes through water.

bazaltina [42]

Answer:

Phospholipid is the molecules that are amphipathic in nature means the molecule has both hydrophobic as well as hydrophilic regions. The phospholipids are the important constituent of the plasma membrane.

The water and oil gets separate when mix together. If the phospholipid is mixed with the oil and water solution than the oil part is mixed with the hydrophobic part and water will mix with the hydrophilic parts. They can form micelles together.

LekaFEV [45]

Answer;

-Nuclei acid

Explanation;

-Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.

-Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.
