Akimi4 [234]

Answer:

The correct option is B. Fermentation would occur at a similar rate to that of glucose.

Explanation:

Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.

Answer:

c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.

Explanation:

Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.

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
