Transitions occur frequently than transversions; thus using transitions, as opposed to transversions, will be more useful for reconstructing phylogenetic relationships between organisms. more; closely related less; extinct more; extinct less; closely related more; distantly related

The correct answer would be more; closely related.

A transition refers to a point mutation in which a purine is converted into another purine (A↔G) or a pyrimidine is converted into another pyrimidine (T↔C).

In contrast, the transversion refers to a point mutation in which a purine is converted into pyrimidine or vice versa.

A transition is more common in nature as the conversion or exchange between similar nucleotide is easier as compared to the exchange between different types of nucleotide.

As they occur more frequently they would be more helpful in making phylogenetic trees between closely related organisms.

me two

explanation:

because i hate it

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.
