Explanation:
Cellulose is a structural component of the plant cell wall. It is a polysaccharide consisting of a long linear chain of multiple β - 1, 4 linked glucose units.
Cellulose is difficult for most animals to digest except herbivores because they lack the ability or enzyme to digest cellulose. This enzyme needed is the cellulase which cleave to its β - 1,4 glycosidic bond and hydrolysis it into its constituent molecules (glucose).
The prefix “hydro-“ relates to water
The research party began by exploring the embryonic development of whales' cousins, the dolphins. These creatures are intriguing because, for a brief time during development, they sprout hind limbs . That's why dolphins lose their 'legs'.” In whales, however, the story is more complex.
The right answer is higher-than-average sea levels.
With the rise in CO2 level that caused an increase in air temperature and sea surface temperatures. At this time, they were the highest ever recorded. In addition, the rise in mean sea level continued and the extent of Arctic sea ice was well below normal for most of the year.
