Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
They would use a microscope to test it out.

Answer:
A. Each of the new double stranded DNA molecules contains one of the original intact strands and one completely new strand.
Explanation:
DNA replication is a semi-conservative process. During DNA replication, the two parental DNA strands are separated to serve as the template. DNA polymerase extends the RNA primers by the addition of the deoxynucleotides complementary to the sequence of the template DNA strand.
After replication of complete length of template DNA, two DNA double helices are formed. Each of the new DNA double helices contains one parental template strand and one newly formed DNA strand. This is why the process is called to be semi-conservative.
