<span>Protein</span>

<span>Cilia and flagella are made up of microtubules covered by plasma membrane and they projection from the cell. Thus, cilia are flagella are motile and designed to move substances over or around the cell and they can as well move the cell itself. In eukaryotes, they are conserved in their polypeptide composition, structure and function as motile and sensory organelles.</span>

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine
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

Sara read in a book that in 1800, the Italian physicist Alessandro Volta observed that two metals connected by a conducting liqu
torisob [31]

Answer:

the process described in the question, described by Alessandro Volta refers to superconductivity, in which two metals connected by a conductive liquid produce a continuous transfer of electrons, these metals are considered superconductors since they do not have electrical resistance and this is always maintained and when the temperature is adequate, different from terms such as the resistance that is the impediment to the flow passage, or to the electric static in which the energy accumulation is maintained without movement or transfer or the electric current that is the energy in the same metal.
