White blood cell classification
Brain. This organ serves as the center of the central nervous system. It exerts control over the other organs in the body. It acts on other orgasn both by controlling muscle activity and secretions of hormones. The response of brain primarily depends on the stimuli from the environment.The interior of the brain whem viewed will show gray matter and white matter. Brain operations is now usderstood however, the way they cooperate is still not fully understood. Function controlled by brain are perception, motor control, arousal, homeostasis, motivation, learning and memory.
Answer:
Allows to reabsorb water.
Explanation:
The kidney uses energy to generate an osmotic gradient (that is the difference in the concentration of two spaces separated by a membrane). This gradient allows the kidney to reabsorb water, and so create more concentrated urine or less concentrated, depending on how hydrated the body is.
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).
