The statement that best describes the work of these researchers is "As a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done." I hope my answer has come to your help. God bless and have a nice day ahead!
Answer: Hydrogen bonds.
Explanation: This seems like more of a chemistry question, but basically hydrogen bonding is way stronger than any other kinds of bonding, and because water molecules are all hydrogen bonded, they cling together a bunch and are thus super cohesive.
A portion of the electromagnetic spectrum is visible to the human eye, but I'm not sure what your options are.
If there's this picture in the question, the right answer is metaphase.
A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.
