A variation is a reference to the differences or deviations, such as the structure and form, as for crossing over is the exchange of genetic material between the non-sister chromatids of the homologous chromosomes during meiosis.
Spiders have malpighian tubules<span> to absorb salts and wastes while humans have microscopic subunits in the kidneys called </span>nephrons to filter blood. Malpighian tubules<span> remove wastes from insects by producing urine and solid nitrogenous waste, which are then excreted from the body.</span>
Transcription in scientific genetics is used to describe the copying of the genetic sequence of DNA on messenger-RNA during expression of genes. On the other hand, translation is used to describe the use of the MRA to convert the gene sequence to amino acid sequences with the help of ribosomes.

Water molecules are COHESIVE due to HYDROGEN bonding. This property of water allows the individual molecules to stick to each other and allows for movement of water from roots to leaves.
The correct answer is B.
Water has certain qualities that allows it to be incorporated into the bodies of living organisms. Water forms hydrogen bonds because it is a polar molecule. The formation of these bonds leads to the cohesive nature of the substance making it suitable as a biological solvent.
