Explanation:
promoters of many genes have regions that are rich in adenines and thymines. what is the most likely reason for this?
Answer:
Many promoters of a hypothetical conserved gene have mostly adenines and thymines. What is the most likely reason for this high proportion of adenines and thymines? This is the region for separating template and non-template strands, and A-T base pairs are easier to separate than G-C base pairs.
Explanation:
Outline the four stages of the demographic transition as it occurred in Europe and North America.
Answer:
Stage 1—High birth and death rates lead to slow population growth.
Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.
Stage 3—The birth rate starts to fall, so population growth starts to slow.
Stage 4—The birth rate reaches the same low level as the death rate, so population growth slows to zero.

Which of these options is not a mechanism to control the opening and closing of ion
channels?
a) ATP binding (ATP gated)
b) Ligand binding (ligand gated)
c) Changes in membrane potential (voltage gated)
d) Distortion of the cell membrane (mechanically gated)
Answer:
D) ATP binding (ATP gated)Explanation:
There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...
So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.
ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).
ATP-gated channels are membrane channel proteins that open in response to binding ATP.
These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.
For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.
In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

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).

why is the study of coral reefs in Palau is important for other coral ecosystem
Answer:
The study of coral reefs is important for providing a clear, scientifically testable record of climatic events over the past million years or so. This includes records of recent major storms and human impacts that are recorded by the changes in coral growth patterns. The Nature Conservancy and the Palau Government have joined forces to design and implement a protected areas network for Palau’s coral reef ecosystem.

which of the following is not an abiotic factor in the prairie ecosystem a water b sunlight c grass d soil
Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).
Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
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

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.

A scientist looks at lung tissue under a microscope. Which level of
organization is simpler than lung tissue?
A. The respiratory system
B. The organism
C. Lung organ
D. Lung cells
Answer:
D. Lung cells
Explanation:
There are many organizations of living things and parts of living things. From simplest to complex the levels are: cells, tissue, organ, system, organism. So, if you have lung tissue then the only simpler organization is cells. These are simpler because cells are what make up tissue, just as tissue makes up organs. Through the levels, the more simple something is then the smaller it is, relatively.
