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).

In the early 1700s, Linnaeus came up with a new system of classification of living things that eventually replaced the one that

antiseptic1488 [7]

Many biological systems classify the organism based on the cells, reproduction, simplicity and complexity. The discovery of the new species and arrangement based on the hierarchy led to the change.

<h3>What was the new classification system?</h3>

Aristotle gave the most primitive biological hierarchical classification system that was replaced by the system of the Linnaeus. He gave the classification based on the taxonomy groups.

With time many new organisms and species were discovered that did not fit in Aristotle's classification system. Hence, with time new systems were established to classify the organism based on many new parameters.

Therefore, option A. new system was established to classify the new organism discovered.

Hello?? Can anyone help me??! PLEASE

kolezko [41]

Answer:

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

I don't think I put enough detail into that explanation but I hope this helps your problem.
