One of the big challenges for a nucleic acid vaccine is actually getting the DNA or RNA to go inside the host cell's membrane. One way to do this is to wrap the nucleic acid up in a little package of macromolecules just like how the golgi body packages things up things we want to export. Based on this description, you would guess that the best thing to package the genetic material would be:

Question Completion:

- a large carbohydrate with partial charges

- a phospholipid

- a nucleic acid carrying

- a negative charge

- a highly polar protein

Based on this description, you would guess that the best thing to package the genetic material would be:

- a phospholipid

Explanation:

Since phospholipids work to provide pathways for various substances across cell membranes, they appear to be the best agents or packages for exporting the genetic material of a nucleic acid vaccine.  As cell membranes, phospholipids can allow selective passage of some substances into and out of the cells, even though they act as barriers to other molecules and ions.

c. movement because i took the test and it lets me review my answers

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
