A scientist uses radioactive isotopes to label a double-stranded molecule 4 points
of DNA. Then the DNA undergoes replication in a non-radioactive
medium. Where are the two original radioactive strands of DNA?
O
a. Both strands are intact, and both are part of the same molecule of DNA.
b. Both strands are intact, and each is part of a different molecule of DNA.
c. One strand is intact, while the other strand is broken apart and distributed among
the new DNA molecules.
d. Both strands are broken apart, and their pieces are distributed among the new DNA
molecules.

Leila has dimples because she received a gene copy from her father that coded for dimples. this means that dimples are an example of a trait that is

Flock x flock y flock z total pieces of food eaten (from previous page) 147 93 60 food percentage* % % % simulated number of birds in flock for 3rd generation** * divide each flock's total pieces of food by 300, the total number of pieces of food eaten. ** multiply the food percentage for each flock by the total number of birds (30).

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
