If color blindness is an x-linked recessive trait, what genotype in a father and a mother would be predicted to produce a 1: 1 ratio of normal to color-blind offspring?

a.) unaffected father and unaffected (non-carrier) mother
b.) unaffected father and carrier mother
c.) affected father and carrier mother
d.) affected father and unaffected (non-carrier) mother

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more

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.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
