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
An example of a communicable disease is
A - cancer.
B - chronic respiratory disease.
C- diabetes.
D -giardiasis.
Answer:
D giardiasis is the correct answer :)
An example of a communicable disease is giardiasis, which is in option D. Giardiasis is an example of a communicable disease. It is caused by a microscopic parasite called Giardia lamblia.
This disease affects the digestive system, causing symptoms such as diarrhea, abdominal cramps, bloating, and nausea. It is typically transmitted through the ingestion of contaminated food or water that has been contaminated with the parasite. Chronic respiratory disease includes conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, which are usually caused by long-term exposure to irritants or genetics and are not directly communicable.

B .2, 4, 3, 5, 1
C. 1, 2, 3, 4, 5
D. 4, 2, 1, 5, 3
Answer:
The correct sequence of events that occurs during protein synthesis? A
Explanation:
2. DNA is used as a template to create mRNA, which leaves the nucleus
4. mRNA molecule binds to a ribosome
1. tRNA brings the correct amino acid specified by the mRNA codon
3. Amino acids are bonded together to make a polypeptide (protein)
5. The ribosome releases both the mRNA molecule and the polypeptide (protein)
During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.
What events occur during protein synthesis?Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.
DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.
In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.
Therefore protein synthesis starts with DNA, hence option a is correct.

how do I write the equation P^2 = kA^3, so that I'm solving for the variable K?
Answer:
k = (P^2)/(A^3)
Explanation:
Step 1: Flip the equation.
[tex]kA^3 = P^2[/tex]Step 2: Divide both sides by A^3.
[tex]\frac{kA^3}{A^3} = \frac{P^2}{A^3}[/tex] [tex]k = \frac{P^2}{A^3}[/tex]Therefore, the answer is [tex]k = \frac{P^2}{A^3}[/tex].
what will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?
A cell that completed mitosis but does not undergo cytokinesis PRODUCES one cell with two nuclei, each identical to the nucleus of the parent cell. Cytokinesis is the last phase of cell division.
Cytokinesis is the process by which a parental cell divides its cytoplasm to produce two genetically identical daughter cells, each one containing one cell nucleus.
Cytokinesis occurs in both types of cell division, i.e., mitosis and meiosis.
In animal cells, cytokinesis occurs by the emergence of a contractile ring that appears just beneath the cell membrane.

what is the approximate percentage of total fixed nitrogen attributed to human activities?
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

Answer:
hi b is the correct one<3 have a good day
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.

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answer:3/13
Explanation:
Answer:
x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2
x = 1/2
