C because fish take many more years to fossilize due to being contained/living in water their bodies are harder to break down
Answer:
The correct answer is "The rate of facilitated diffusion is decreased".
Explanation:
Most cells obtain their nutrients by different kinds of diffusion. One property that affects the rate of diffusion is the cell's surface area-to-volume ratio. The smaller the cell's surface area-to-volume ratio, the higher the rate of diffusion. This happens because is easier for a small cell to get the nutrients to the center than to a large cell. This is the case for facilitated diffusion. Therefore, the rate of facilitated diffusion will be decreased when a cell's surface area-to-volume ratio is greatly increased.
This is associative learning.
The reactions of George and Ken are based on when they are startled. George will learn to associate his sister's crying with him being startled because it happens every time his sister cries.
Whereas Ken will not know when his sister will cry or when he will be startled by the crying so this has no affect on Ken.
Hence, crying will affect George but not Ken.
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).
So whats the answer. My best logical guess is D. Why would the turtle have to go above the water. If their living in a pond, then studying them above water makes no sense. So it's most useful if they are remaining underwater for many minutes at a time then reach for the surface, so that's the answer most likely, but i have no idea.
So... <em>D. A turtle may remain underwater for several minutes, but then surfaces for at least a brief moment.</em>
