Answer: hella late but,
Uracil pairs only with adenine
Guanine pairs only with cytosine.

Answer:
(B) HEK cells exposed to the most hypotonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.
Explanation:
The function of AQP5 (an aquaporin) is to allow the water to move into or out of the cell down the concentration gradient. When placed in hypotonic solutions, the internal environment of HEK cells will be hypertonic. Water always moves from hypotonic (higher water concentration) to hypertonic (lower water concentration) solution.
Hence, the HEK cells exposed to the hypotonic conditions will localize AQP5 in their membranes to allow the water to move from out hypotonic conditions to the inner hypertonic environment.

The question is incomplete. The complete question is as ollows:
For DNA, a plot of the change in absorbance versus temperature would be ________, which indicates ________.
Variable in shape (hyperbolic, linear or sigmoidal); the dependence of the denaturing process on the sequence of the DNA
Linear; the breaking of bonds between the base pairs is an independent process
Hyperbolic; a simple equilibrium between the native conformation and denatured DNA.
Sigmoidal; cooperativity where disruptions in the base stacking at one position destabilizes the stacking in neighboring base pairs
Answer:
Sigmoidal; cooperativity where disruptions in the base stacking at one position destabilizes the stacking in neighboring base pairs
Explanation:
DNA is the main genetic material of all the living organisms except in case of few viruses. DNA contains the nitrogenous bases ( adenine, guanine, thymine and cytosine), pentose sugar and phosphate bond.
The DNA can absorb light due to the presence of the absorbance property of nitrogenous bases. The shape of the plot of the change in absorbance versus temperature is sigmoidal. This is because the temperature denatures the DNA and breaks the hydrogen bond present between the nitrogenous bases. The breaking of the bonds between the nitrogenous base will disrupt the bonding at the neighboring base pair also.
Thus, the correct answer is option (4).
Answer:
Yes because we are pulloting the air hurting the crust along with pulloting the air
