Ais a change in the dna sequence. mutation displacement

Mutation

Explanation:

A mutation is a sudden change that occurs at random in the DNA base sequence and can be transmitted to offspring.

In the DNA molecule we find the genes with the characteristics of the organism. All information is encoded by a sequence of nitrogenous bases in the gene itself, and it is from this base sequence that a specific protein is constructed. If, for some reason, there is a change in the sequence of nitrogenous bases of DNA, there will also be change in the amino acid sequence that forms the protein, and consequently in the properties of the protein. In fact, the alteration that occurred in the base sequence of DNA was a mutation, and it may be sufficient to trigger a new feature in the body.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
