Answer:
Chitin, Cellulose and Peptidoglycan (B, C and D)
Explanation:
Both chitin and cellulose are composed mainly of glucides, bound by glycosidic bonds of the Beta 1-4 type. This is largely why they cannot be digested by most non-herbivorous animals.
As for peptidoglycans, it is a net. It is a molecular framework present in bacteria that has β1-4 and α1-4 bonds in different proportions.
So they aren't broken quickly, and we aren't jelly, bones help us stay strong and upright
Koalas, scientifically known as <em>Phascolarctos cinereus</em>. They found in the variety of habitats such as coastal islands and eucalyptus forest. They live in societies and rely on genetic diversity for survival like any other species. But in case of Koalas, the genetic diversity low over 120 years. Low diversity indicates that they practice inbreeding for reproduction. As a result the population size decreases.
Answer:
hope this makes sense
Explanation:
In an experiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: The difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group.
