Read this section of Dwayne’s text about physical science. Look around. Everything you see is made up of atoms, which are basic units of matter. Atoms that are linked together create a molecule, the most basic life form. A microscope is a tool used to look at very small objects. To see individual atoms, scientists must use a special microscope called a scanning tunneling microscope (STM). What should Dwayne do to help his readers understand the text, and why? A. Insert a diagram of a microscope with each part labeled so readers understand how scientists study atoms and molecules. B. Set the term “scanning tunneling microscope” in red font so readers understand that this is a key term that they should look up. C. Add a photograph of a scientist looking through a microscope with the caption “Scientists study atoms and molecules.” so readers will understand why scientists use microscopes. D. Insert the heading Atoms and Molecules above the first paragraph to indicate that paragraph’s main idea, and add the heading Microscopes above the second paragraph to indicate the main idea of that paragraph.

Explanation:

Insert the heading Atoms and Molecules above the first paragraph to indicate that paragraph’s main idea, and add the heading Microscopes above the second paragraph to indicate the main idea of that paragraph.

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

with very few exceptions,' the constitutional provisions relating to the president have not been changed at all since

they were ratified in 1787. but in the late twentieth century, those provisions do not mean what they meant in

1787. the constitution is a legal document, and it is enforced judicially; but its meaning was hardly fixed when it

was ratified. in particular, the contemporary president has

far broader powers than the original constitution contemplated. it is remarkable but true that large-scale changes in

the authority of the president have been brought about

without changes in the constitutional text, but nevertheless

without significant illegality.

this is a paradox. is it not clear that constitutional

changes, if not textual, are illegal? the paradox has considerable relevance to our current thinking about the presidency in particular and about constitutionalism in general.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is
