Explanation:1. Polar molecules have two regions but the regions are with a partial +tive charge and a partial -tive charge
2. Water is a polar molecule because of the partial +tive and partial -tive charge hence it dissolves polar solute(solute with ions)
3.The more electronegative region bonds with an electrophile to form a weak bond(Hydrogen bond)
Animal cells migrate during morphogenesis. not plant cells
Answer: Bacteria will use the oxidised form of sulphur. Among all the forms of sulphur molecule such as sulphate which is the more oxidised form and also the other forms like thiosulphate,elemental sulphur, sulphite, hyposulphite can be used as an electron acceptor. As the coupling of these organic compounds occur, these sulfur bacterias obtain energy from the subsequent oxidation and then reduction of sulfur forms from sulphate to sulphide which is then released in the environment.
