Hope I helped :)
That they were probably on land and that they evolved into sea animals or that that mountain used to be an ocean or water source and that it dried up and a mountain grew there. I'm not positive that this is correct though.
<u>Answer:</u>
In snapdragons, if a plant has one ordinary copy of the quality for red shading and one mutant copy, delivering non-utilitarian protein, it's blooms are pink , the transformation that is caused would have made the blossoms white by not creating the red shading.
Since the snapdragon is obliged by incomplete dominance, one allele for red (R), and one for white (W), would realize a pink flower. The genotype for the pink sprout is Rr and the genotype for the white bloom is rr. This would incite a half plausibility of the successors having a phenotype of pink.
What's more the plant pursues the rule of co strength for its phenotype articulation and in this way the red and the white communicated together yields a pink blossom. Co-strength is a marvel wherein both the characters are communicated similarly.
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).
bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic
