The FDIC (Federal Deposit Insurance Corporation) was created after the Great Depression with the passage of the Banking Act of 1933, also known as the Glass-Steagall Act.
The Banking Act of 1933, commonly referred to as the Glass-Steagall Act, was enacted in response to the economic turmoil caused by the Great Depression. One of the key provisions of the act was the establishment of the Federal Deposit Insurance Corporation (FDIC). The FDIC was created to restore public confidence in the banking system and provide stability to depositors.
Under the FDIC, bank deposits up to a certain limit (initially set at $2,500 and later increased) were insured against loss, providing assurance to depositors that their money was safe even if a bank failed. This measure aimed to prevent bank runs and protect individuals' savings, thereby promoting stability in the banking industry.
The FDIC's role expanded over the years, and it continues to serve as an independent agency of the U.S. federal government responsible for insuring deposits, supervising financial institutions, and resolving failed banks. The establishment of the FDIC through the passage of the Banking Act of 1933 marked a significant step in financial regulation and contributed to the restoration of confidence in the banking system after the Great Depression.

How it could be possible to change an amino acid within a protein but not affect that protein's function
It is possible for a change in amino acid within a protein to not affect its function under certain conditions. This can occur if the substitution of one amino acid with another results in a conservative change, meaning that the substituted amino acid has similar properties to the original one.
Proteins are composed of long chains of amino acids, and each amino acid has unique chemical properties that contribute to the protein's structure and function. However, some amino acids share similar characteristics, such as size, charge, or hydrophobicity. If an amino acid substitution preserves these shared characteristics, it may not significantly alter the overall structure and function of the protein.
Additionally, the specific location of the amino acid within the protein can play a role. If the substituted amino acid is located in a region that is not critical for the protein's function or stability, the change may have minimal impact on overall protein function.

resting pulse rate is an important measure of the fitness
Resting pulse rate is an important measure of the fitness of a person's cardiovascular system with a lower rate indicative of greater fitness. - True
Resting heart rate, commonly referred to as resting pulse rate, is a crucial indicator of how well-trained a person's cardiovascular system essentially is. The general rule is that more cardiovascular fitness is indicated by a lower resting pulse rate. The heart becomes more proficient at pumping blood as a result of regular aerobic activity and a healthy lifestyle, which can lower resting heart rate.
A greater resting heart rate, on the other hand, can indicate a less healthy cardiovascular system. Adults typically experience a heartbeat of 70 beats per minute, or their average pulse rate. People who exercise or run may occasionally have a slower heart rate; however, this decrease in heart rate may only last a brief period of time.

which term most accurately defines ventilation changes during exercise?
The term that most accurately defines ventilation changes during exercise is "pulmonary ventilation".
Pulmonary ventilation, also referred to as "ventilation," is the total volume of air entering and leaving the respiratory tract each minute. It is the process of moving air in and out of the lungs and is frequently increased during exercise to meet the increased oxygen demand by the body's tissues. Ventilation is critical because it is the only means for transporting oxygen and carbon dioxide in and out of the lungs. The increased ventilation that occurs during exercise is referred to as "exercise hyperpnea."This increased ventilation helps to meet the body's increased metabolic requirements during exercise by increasing the oxygen delivery rate to the lungs.
This is achieved through several physiological mechanisms, including an increase in tidal volume and breathing frequency and a decrease in the physiological dead space. This is why the term "pulmonary ventilation" is most accurately used to describe ventilation changes during exercise.

in normal, unforced breathing, _______ involves muscular contractions (active), while ________ requires no active muscular effort (passive).
In normal, unforced breathing, inspiration involves muscular contractions (active), while expiration requires no active muscular effort (passive).
What is normal breathing?
Normal breathing is a respiratory rate of 12-18 breaths per minute in an adult. The air breathed in and out is distributed to the lungs and body tissues via a complex process that involves several muscular and non-muscular mechanisms. The respiratory muscles, such as the diaphragm, intercostal muscles, and accessory muscles, contract and relax to change the lung volume and the airflow during breathing.Inspiration, which is inhalation, occurs when the lung volume is expanded, creating negative intrapleural pressure and airflows into the lungs. Active muscular contractions help to increase the volume of the thoracic cavity by contracting the diaphragm, raising the ribcage, and expanding the chest wall.
Expiration, which is exhalation, occurs when the lung volume is reduced, creating positive intrapleural pressure, and air flows out of the lungs. During expiration, there is no active muscular effort required, and it is mainly a passive process that is driven by elastic recoil of the lung and chest wall.In conclusion, in normal, unforced breathing, inspiration involves muscular contractions (active), while expiration requires no active muscular effort (passive).

What factors might cause the blood po2 to go down with exercise, despite the increase in alveolar po2?
The factors might cause the blood PO₂ to go down with exercise, despite the increase in alveolar PO₂ due to compensatory mechanisms such as increased cardiac output and oxygen extraction by tissues.
During exercise, several factors can cause the blood PO₂ (partial pressure of oxygen) to decrease, despite the increase in alveolar PO₂. Here are some factors that can contribute to this phenomenon:
1. Increased Oxygen Demand: During exercise, the body's oxygen demand increases due to the higher metabolic rate in active muscles. As a result, oxygen is rapidly consumed by the working muscles, leading to a decrease in the oxygen content of the blood.
2. Redistribution of Blood Flow: During exercise, blood flow is redirected from non-essential organs, such as the digestive system, to the working muscles. This redistribution of blood flow can decrease the oxygen content in systemic arterial blood.
3. Increased Ventilation Perfusion Mismatch: Exercise can lead to an increase in ventilation (breathing rate) to meet the increased oxygen demand. However, blood flow to certain areas of the lungs may not match the increased ventilation adequately, leading to a ventilation perfusion mismatch. This mismatch can result in reduced oxygen transfer from the alveoli to the blood.
4. Shortened Transit Time: During exercise, cardiac output increases, causing blood to flow more rapidly through the lungs. The shortened transit time may limit the opportunity for oxygen to equilibrate fully between the alveoli and the blood, resulting in a lower blood PO₂ .
5. Increased Carbon Dioxide (CO₂) Production: Exercise leads to an increase in CO₂ production due to increased metabolism. Elevated CO₂ levels in the blood can cause vasodilation and shift the oxygen-hemoglobin dissociation curve to the right, making it easier for oxygen to dissociate from hemoglobin and reducing blood PO₂.

Which of the following structures would not be found in a prokaryotic cell?
a. cell membrane
b. nucleus
c. chromosomes
d. ribosomes
e. flagella
In a prokaryotic cell, the structure that would not be found is : nucleus.
The correct answer is option B.
Prokaryotic cells are simple, single-celled organisms that lack a nucleus and other membrane-bound organelles found in eukaryotic cells. Instead, they have a more primitive organization and structure. Here is a brief explanation of the structures mentioned:
a. Cell membrane: The cell membrane is present in both prokaryotic and eukaryotic cells. It surrounds the cell and acts as a barrier, regulating the movement of substances in and out of the cell.
b. Nucleus: This is the defining characteristic of eukaryotic cells, which contain a well-defined nucleus that houses the genetic material (DNA). In prokaryotic cells, the genetic material is not enclosed within a nucleus but is instead present in a region called the nucleoid, which is not membrane-bound.
c. Chromosomes: Prokaryotic cells contain chromosomes, which are the main structures that carry the genetic information. However, these chromosomes are not enclosed within a nucleus as in eukaryotic cells. In prokaryotes, the DNA is typically a single, circular chromosome found in the nucleoid region.
d. Ribosomes: Ribosomes are present in both prokaryotic and eukaryotic cells. They are responsible for protein synthesis and are involved in translating genetic information into functional proteins.
e. Flagella: Prokaryotic cells can have flagella, which are whip-like structures used for locomotion. These flagella are simpler in structure compared to the flagella found in eukaryotic cells.
In summary, the structure that would not be found in a prokaryotic cell is the nucleus. Prokaryotes lack a true nucleus and other membrane-bound organelles found in eukaryotic cells, but they do possess a cell membrane, chromosomes, ribosomes, and may have flagella for movement.
Therefore, the correct option is B.

Which of the following statements regarding tobacco and cardiovascular disease risk is FALSE?
Multiple Choice
a. Tobacco decreases levels of LDL cholesterol.
b. Tobacco triggers spasms that close off blood vessels.
c. Tobacco damages the inner lining of blood vessels.
d. Tobacco decreases levels of HDL cholesterol.
"Tobacco decreases levels of LDL cholesterol" is the false statement regarding tobacco and cardiovascular disease risk.
The correct answer is option A.
Tobacco use is known to have detrimental effects on cardiovascular health, and all the other options (B, C, and D) correctly describe the negative impact of tobacco on the cardiovascular system.
Option B is true. Tobacco can trigger spasms in blood vessels, leading to their constriction or closure. This can reduce blood flow and potentially result in conditions like angina or heart attacks.
Option C is true. Tobacco use damages the inner lining of blood vessels, a condition known as endothelial dysfunction. This damage contributes to the development of atherosclerosis, where plaque builds up in the arteries, narrowing and stiffening them, and increasing the risk of heart disease and stroke.
Option D is also true. Tobacco use can lower levels of high-density lipoprotein (HDL) cholesterol, often referred to as "good" cholesterol. HDL cholesterol plays a crucial role in removing excess cholesterol from the bloodstream, and decreased levels of HDL cholesterol are associated with an increased risk of cardiovascular disease.
However, option A is false. Tobacco use does not decrease levels of low-density lipoprotein (LDL) cholesterol. In fact, smoking can lead to increased levels of LDL cholesterol, which is considered the "bad" cholesterol due to its association with the development of atherosclerosis and cardiovascular disease.
In summary, while tobacco triggers blood vessel spasms, damages the inner lining of blood vessels, and decreases levels of HDL cholesterol, it does not decrease levels of LDL cholesterol, making option A the false statement regarding tobacco and cardiovascular disease risk.

the fetus is highly susceptible to serious structural damage from exposure to many teratogens throughout pregnancy.
The fetus is highly susceptible to serious structural damage from exposure to teratogens during pregnancy.
Teratogens are substances or factors that can disrupt normal fetal development and cause birth defects. The developing fetus is particularly vulnerable to the effects of teratogens during critical periods of organ formation and growth. Teratogens can include certain medications, chemicals, infections, radiation, and maternal behaviors such as smoking or alcohol consumption.
Exposure to teratogens can result in a wide range of structural abnormalities, such as limb defects, heart malformations, central nervous system abnormalities, and facial abnormalities. The severity and type of birth defects depend on the timing, duration, and intensity of the exposure to the teratogen.
It is crucial for healthcare providers to educate pregnant individuals about the potential risks of teratogen exposure and encourage them to avoid known teratogens. Preconception counseling, early prenatal care, and a healthy lifestyle are essential in minimizing the risk of teratogenic effects and promoting optimal fetal development.

routine hand washing for dental healthcare personnel includes the use of
Routine hand washing for dental healthcare personnel includes the use of water and antimicrobial soap.
Instead of using a particular antimicrobial soap, dental healthcare professionals commonly wash their hands with water and normal or non-antimicrobial soap. Dental healthcare professionals are encouraged by various medical centres to practise conventional hand hygiene procedures, which include washing hands with only water and bar soap. The majority of transient bacteria can be effectively removed from hands using the mechanical action of hand washing and water rinsing.
However, there may be some circumstances, such as in cases of suspected or verified exposure to particular pathogens or when performing surgical procedures, where the use of antimicrobial soap or an antiseptic handwash is advised. Healthcare professionals may be encouraged to use antimicrobial soap or handwash containing antiseptic ingredients in these circumstances.
