Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.
What are Nucleic acids?Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

which solution is hypertonic?
Answer:
the beaker
Explanation:
the beaker (0.5 m salt) has more solvent than the red blood cell (0.1 m salt). Therefore, it means that the red blood cell is hypotonic (more water/solute), and the beaker is hypertonic (more solvent/salt).

Answer:

Explanation:
Water molecules moving across the plasma membrane until solute concentrations are equal on both sides of the membrane best describes the process of osmosis in an animal cell .
Osmosis is the process in which molecules move from a region of higher concentration to that of a lower concentration across a semi-permeable membrane.
Osmosis provides a balance between the elements in which organisms are exposed to. A very high concentration may cause cells to shrink and die hence the reason to maintain a balance for optimal functions and survival.

how can different amino acids affect secondary structure
Answer:
Exposure to positively charged amino acids (arginine and lysine) is found to clearly stabilize the secondary structure. Kinetically, each amino acid promotes folding by generating a large increase in the folding rate with little change in the unfolding rate.

What was the Court’s decision in United States v. Nixon (1974) and how did the decision uphold the idea that even the President of the United States is not above the nation’s laws?
Answer:
The Supreme Court decided that the President was required to turn over tape recordings and other materials that had been subpoenaed by special prosecutor Leon Jaworski.
In trying to withhold some materials related to the Watergate investigation, Nixon's lawyer had argued that the President of the United States "is not subject to the processes of any court in the land except the court of impeachment." The Supreme Court disagreed, in unanimous fashion. They held that the President could not use executive privilege as an excuse for hiding wrongdoing or avoiding prosecution. In an interview some years after his resignation, Nixon still held to his view, claiming that when the President does something, "that means that it is not illegal." He felt that being in the position of President put him above the law. But the Supreme Court had firmly disagreed. They rejected the idea of "absolute, unqualified Presidential privilege of immunity from judicial process under all circumstances." Executive privilege can only protect matters of military or diplomatic confidentiality
6. Identify the type of climate data that has the longest data range. 1. microscopic organism 2. data sediment core 3. data tree ring 4. data ice core data
Complementing data, taken from different sources such as tree rings, sediments, and ice, provides significant information about global climatic changes. However, ice core data has the longest data range. (4) is correct.
-------------------------------
Ice core data refers to the information obtained from a sample of ice taken from a glacier or a mountain.
Information kept in the ice is mostly about gases concentration at different moments though time.
Analysis of retained gases in Antarctic ice, through perforations of over 2000 meters deep, has allowed knowing the CO₂ atmospheric concentrations and other gases involved in the greenhouse effect for at least 150,000 years.
These concentrations have varied in the temporal scale of glaciation, showing low concentrations during glacial periods with low temperature and relatively high concentrations during interglacial periods with high temperature.
Between these two periods, abrupt variations in temperature and gas concentration are detected, meaning that changes in CO₂ cause changes in temperature.
The increase in CO₂ is a highly significant component in global climatic change and possibly the best documented.
This information is the best paleoclimatic documents.
Complementing it with marine sediments core and data tree rings makes it possible to know about the principal traits of terrestrial weather in the lasts 420,000 years, practically four glacial-interglacial cycles.
