Freckles is dominant over no freckles. what percentage of offspring would be predicted to have freckles if the father was heterozygous for freckles and the mother did not have freckles

The answer would be 50%.

Let's make a Punnett square for this:

Let F - Freckles

f - no freckles

Father: Ff

Mother: ff (She has no freckles, meaning she does not have the dominant allele)

F f

f Ff ff

f Ff ff

The count would then be 2/4 with freckles and 2/4 without freckles. So the percentage of would be 50% with freckles and 50% without freckles.

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.
