Since the two strands of the dna molecule are complementary, for any given gene
a. the rna polymerase can bind to either strand.
b. only one strand actually carries the genetic code for a particular gene.
c. each gene possesses an exact replica that can be used should a mutation occur.
d. a gene transcribed in the 5' to 3' direction on one strand can be transcribed in the 3' to 5 direction on the other strand.
e. both answers a and b are correct

the fossil record provides evidence of a common ancestor to many species.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
