Researchers use the denaturation temperatures of hybrid double helices to compare evolutionary relatedness. Complementary strand
WITCHER [35]

Answer:

The strands of the hybrid helix are less complementary than the original helix.

Explanation:

Complementary DNA strands are bonded to each other through hydrogen bonding. The nitrogenous base adenine (A) forms 2 hydrogen bonds with thymine (T). Guanine forms 3 hydrogen bonds with cytosine. Due to the presence of 3 hydrogen bonds, GC rich regions of DNA or RNA are more strongly bonded.

Therefore, if the two strands will be less complementary or contain more AT rich regions, the double helix will denature or melt at a lower temperature.

One reason that atp is a source of energy is that the products of atp hydrolysis have less free energy
Svetlanka [38]
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state

Describe the disadvantages of an open circulatory system relative to a closed circulatory system.
sp2606 [1]

Explanation:

<em>The disadvantage of a closed circulatory system is that with the blood always contained in vessels, it's under higher pressure. This means it can flow faster, which is necessary for supporting the metabolic rate of more complex animals such as vertebrates. Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism</em>.
