Answer:
Compared to X-ray crystal diffraction and magnetic resonance, single-particle cryo-electron microscopy has unparalleled advantages. This technique does not require protein crystallization, requires only a small amount of protein sample, and is suitable for samples of different sizes, for example, as small as 64. 000 hemoglobin, large particles up to several megadaltons. Frozen electron tomography can even be used for larger biological samples, such as tissues and cells, to obtain high resolution images and structures of macromolecules and their complexes in situ in cells or tissues.
Another advantage of cryo-electron microscopy is that it presents more than just static structures. Sample preparation by cryo-EM can be done in an instant, capturing dynamic changes in protein molecules. Perhaps in the future, people can observe intermolecular interactions and their dynamic changes in cells or tissues and organs. Perhaps in the future, people can observe intermolecular interactions and their dynamic processes in situ in cells or tissues and organs.

Difference in rate of respiration of various sugars
Explanation:
It will be observed that sucrose and sugar solutions are having the highest rates of respiration. The artificial sugars like Splenda, glu-cose, Equal follows sucrose and sugar solutions. among the artificial sugars, Splenda has a higher rate of respiration than the others.
Compared to an artificial sugar, sucrose seems to provide a good starting material for fermentation.
Among artificial sugars, Splenda which has a higher content of sucralose, maltodextrin and dextrose sugars can provide good starting material for the yeast cells undergo fermentation and cellular respiration.
Answer:
radioactive dating of each layer would be the right one
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
