Answer: The correct answer is -

Radial symmetry is a body plan of organisms where the body is divided into two equal parts by any plane that passes through the central axis (such as in Echinoderms and Coelentrates) of the body.

It is very useful for the sessile organisms (that are fixed or attached at one particular place through base) because there is an even distribution of sensory receptors in their body, which helps in detecting their threats (like predators) from all directions equally. Also, they can grab food from all direction equally by being attached to one place.

yanalaym [24]

It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.

  • Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).

  • In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.

  • Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA
