If both of those sexual partners are faithful to each other, and only have sexual relations with one another, then there isn't a high probability that either of them is going to get HIV. If they want to be sure, they should use protection, such as condoms, to prevent getting HIV through body fluids. And they should always be honest with each other in case one of them has that disease.

Answer: C. elegans is transparent and has only about 1000 cells, allowing the cells to be followed during development
Explanation:
Caenorhabditis elegans is transparent, thus the behavior of each cell can be studied throughout its development period.
The monomers:
In chemistry, a monomer is a most often organic substance used in the synthesis of oligomers and polymers during an oligomerization or polymerization reaction1. The word monomer comes from the Greek monos, one or only one, and meros, part.
In biology, a monomer (or subunit) is the building block of multimeric proteins such as hemoglobin. The arrangement of the monomers with respect to one another is described by the quaternary structure of the protein.
Polymers:
Polymers are a class of materials. From a chemical point of view, a polymer is a macromolecule (molecule consisting of the repetition of many subunits (or many monomers)).
Polymers can be made naturally (by living organisms) or artificially (by humans).
Answer:
The larger nucleus of oxygen exerts a stronger pull on the shared electrons in the water molecule, creating the partial negative charge on the oxygen atom, resulting in the polarity.
