The correct answer is D.) The diffusion of water across a semi permeable membrane. Hope that helps.
Answer:
Liquids have an indefinite shape, while solids have a definite shape.
Answer:
Explanation:
In the structure of Nucleic acids the nucleobases (nucleotide and bases) are arranged is a specific form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.
These nitrogenous bases of (A,T,C.G) pairing in DNA are in planes in geometry.The bases planes stack with one another.This form of arrangement give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure
Therefore in water and other aqueous solution the stability of structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction among the bases, than the hydrogen bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)
B. prokaryotes because they do not contain organelles or a nucleus. the following above in the question all are eukaryotic and contain organelles and a nucleus
the difference in altitude represented by the space between two contour lines on a map. At least i think youre looking for the definition. And if you are hope this helps :)
