What is the success rate of implementation of transgenic embryos in surrogate dams? A) 50% B)100% C)25% D)<12.5% E12.5%

D)<12.5%

Explanation:

Transgenic means one or more than one DNA sequences are introduced from another species by an artificial means into a surrogate dams to form a new offspring. Animals are usually make transgenic by a small sequence of the foreign DNA which is injected to the developing embryo of the surrogate mother.

The success rate for such implementation is nearly less than 12.5%, where most of the trial do not survive the injection. The surrogate mother cannot developed in most cases the implementation of one or more species into another.

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.
