So every organism is individually classified without the worry of mixing up two organisms like a fly and nat.
The answer is D. To test the growth of alfalfa plants with and without nitrogen rich fertilizer
The answer is diffusion. Since the patient’s blood is high is waste products such as urea, the waste products diffuse into the dialyzing solution used in the dialysis machine. To remove excess water and sodium ions from the blood, however, the dialysis machine utilizes ultrafiltration process. This is achieved by lowering the hydrostatic pressure of the dialyzing solution against that of the patient's blood plasma.
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).
