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.
Science is best known for logics.
Science is so interesting such that it method of processing and validating logics and facts with verifiable hypothesis and experimental evidence.
This scientific method is also an empirical method of acquiring knowledge which simply involves making observation, establishing hypothesis, designing experiment, analysing result and drawing conclusions.
A hypothesis is a reasonable explanation for a particular observed natural phenomena.
<h3>What is science?</h3>
Science can simply be defined as the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
So therefore, science is best known for logics

Answer:
- Human Health: Human health is a result of environmental degradation. Areas exposed to toxic air pollutants can cause respiratory problems like pneumonia and asthma. Millions of people are known to have died due to the indirect effects of air pollution.
- Loss of Biodiversity: Deforestation, global warming, overpopulation, and pollution are a few of the major causes of loss of biodiversity.
- Tourim Industry: The deterioration of the environment can be a huge setback for the tourism industry that relies on tourists for their daily livelihood. Environmental damage in the form of loss of green cover, loss of biodiversity, huge landfills, increased air, and water pollution can be a big turn off for most of the tourists.
