First  you  determine  the   total mass  of  the   strawberries used
Then  determine  the    mass  of  the   DNA  obtained  from  the  strawberries
percentage  mass  is  therefore  equal  to  mass  of  the  DNA  obtained  divided  by  total  mass  strawberries  multipy  by   a  100

<span>Weigh the strawberry and record its total weight. Cut off a small piece of the strawberry, weigh the piece, and record the piece's weight. Crush the weighed piece and treat it with a substrate that will suspend particles with negative charges. Filter the materials suspended in the substrate to isolate the strands of DNA. Use imaging tools to find the exact mass of the DNA. Divide that mass by the mass of the strawberry piece and multiply by 100% to get the percentage of the strawberry's mass that is DNA.</span>

Evolutionary theory has become the central organizing principle of biological science. Could this scientific theory ever become
sveta [45]

The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.

Answer is A) Yes, if scientists decide that enough evidence supports the theory.

steposvetlana [31]
It will rain next. The moist air has lots of gas water. And when the warm gas water meets the cool temperature in the atmosphere, it will become liquid water. And when liquid water becomes more and more, it will form rain.

Ans.

Paper waste prevention is defined as a practice to reduce or eliminate use of paper, which is potential for the efficient use or disposal of paper. It decreases the environmental impacts due to both paper manufacturing and paper recycling, such as demands on forest resources).

Use of advance technologies, such as E-mail (electronic mail) can help in cut down on paper waste. Nowadays, E-mail has replaced conventional letters and faxes as it is more eco-friendly than letters and faxes, which needs paper consumption.
