The four laws or principles that are involved with the study of Stratigraphy are the following:
1. Principle of original horizontality
2. Law of superposition
3. Law of crosscutting relationships
4. Principle of Lateral Continuity
5. Principle of Faunal Succession
6. The Law of inclusions
Therefore, the correct answers would be 1, 2 and 4. Hope this answer helps.
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.
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
i dont trust it,it may say brainliest answer but its WRONG its actually, D .
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>.
