Answer:
B: A location where 2 of Earth's plates meet
Explanation:
A boundary is the outer edge of something, and the entire Earth is covered with plates, so all boundaries are touching.
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).
2.) behave normally
the bear should behave normally because if the lighting is the only problem here the other two options wouldn't make sense as the temperature will stay as though it were winter and foraging wouldn't change because bear only go out in darkness to avoid people, and people are not a part of the perfect environment.
sensory and motor areas undergo major growth spurts during middle childhood.
- The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
- Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
- Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
- More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
- The brain is driven by the motor system, which also drives sensory stimulation and feedback.
- These abilities must advance and grow in order to support behavior and academic learning.
- Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

Answer:
C. double helix
Explanation:
Watson and Crick discovered that DNA molecules are double-helical structures. According to them, each DNA molecule has two DNA strands that are wound around an imaginary axis to form a double helix. These two DNA strands are held together by complementary base pairing between their bases. They discovered that a purine base pairs with a pyrimidine base to maintain a constant distance between the two strands of a double helix.
