It became apparent to watson and crick after completion of their model that the dna molecule could carry a vast amount of hereditary information in its in an analysis of the nucleotide composition of dna. which of the following is true?
a) the strands that make up dna are antiparallel.
b) this means that the nature of dna creates nonparallcl strands the 5' to 3' direction of one strand c) nuts counter to the 5* to 3' direction of the other strand.
d) base pairings create unequal spacing between the two dna strands.

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
