Answer:

Helium is considered as noble gas or inert gas because it belongs to noble family in the periodic table.

Explanation:

Helium is stable atom because it has complete outermost shell i. e. 2 electrons. Except noble gases, all the elements are reactive because they have incomplete outermost shell so for attaining stability, they form bonds with each other and attain the electronic configuration of noble gases. Helium has given the name of noble gas due to stability.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.

Stels [109]

EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.
