The density of ice is less than water - that's why it floats on water. I think this property is unique in liquids.
If ice was equal or heavier density than water then the oceans would be solid except for near the surface, which would be very bad for aquatic life!!
Compare: They both are products of DNA. They both are equally important to a living organism. Contrast: Genotype is the genetic makeup, while Phenotype is the physical appearance. Genotype can't be seen but phenotype can.
Answer:
d. An enzyme will generally bind only one substrate.
Explanation:
Enzymes are the catalytic biomolecules. The enzymes have specific pockets called active sites. Substrates bind to these pockets of enzymes. The active site of an enzyme is compatible to allow a specific substrate to bind to it. This allows specificity to the enzymes and ensures that a specific enzyme binds to a particular substrate only. A substrate can bind to the active site of its enzyme, it can not bind to any other site of the enzyme. Moreover, substrate binding induces a conformation change in the active site of its enzyme to favor the binding of more substrate molecules.
