A gene found in naturaly occurring soil bacterium, Bacilus thuringiensis (B), contains a protein that kills certain insects. Scientists have genetically modified certain organisms such as corn, potatoes, and cotton by introducing the B: gene into their DNA in order for these plants to have this desired trat. Which question were the scientists most likely trying to answer?
А)How can farmers produce more nutritional crops? B) How can farmers use less insecidies on their crops? C) How can farmers reduce the amount of land needed to grow their crops ? D) How can farmers reduce the amount of fertilizers they apply to the soil for their crops ?

explanation:

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.
