ki77a [65]

Answer:

1.a sequence of sugars, phosphates, and nitrogenous organic bases: Nucleic acid

2.a complex molecule containing the genetic code: DNA

3.a nucleic acid that participates in the synthesis of proteins: RNA

Explanation:

Nucleic acids are the biomolecules that are composed of a sequence of nucleotides. Each nucleotide has a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acid called DNA and RNA. DNA differs from RNA with respect to the pentose sugar and the presence of a thymine base. The sequence of the template DNA strand serves as a genetic code.

It is copied into the nucleotide sequence of mRNA during the process of transcription. The molecules of mRNA serve as a template for the synthesis of proteins when their nucleotide sequence is read in the form of genetic triplets.

Gas makes things buoyant, why ? And what are ways that this could be useful?
ryzh [129]

Answer:

Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.

Gas Buoyancy is useful in the following ways;

• Airships

• Steel ships and

• All floating and flying vessels

Explanation:

Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.

It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

The principle explains the reason why objects float and fly.

So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.

This is where the use of a gas comes into play.

Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.

This is what causes objects to float or fly
