a. 6.95-7.05.
b. 7.15-7.25.
c. 7.35-7.45.
d. 6.50-7.50.
The correct answer is [c] 7.35-7.45
The normal range of pH of arterial blood pH 7.35-7.45.
What do you mean by arterial blood?Three different tests—pH, Pco2, and Po2—are typically taken in conjunction to assess the patient's acid-base state, ventilation, and arterial oxygenation. This group of measurements is referred to as arterial blood gases (ABGs). The most significant respiratory gases are oxygen (O2) and carbon dioxide (CO2), and the partial pressures of these gases in arterial blood indicate how well gas exchange is functioning generally.
Age and altitude have an impact on Pao2. Paco2 by height. As a result, Pao2 needs to be determined specifically for each patient, and both results need to be compared to the neighborhood's norms. Because hydrogen is not a gas in blood, it does not impose a partial pressure. However, every arterial blood gas determination includes pH, which assesses hydrogen ion activity. Blood pH should fall between 7.35 and 7.45.
The ABGs may include certain calculated or derived variables. The most helpful of these is the bicarbonate concentration, which may be determined from the pH and Pco2. Others are not necessary and could be confusing, such as base excess and base deficiency.

When people are faced with stressful situations, an array of symptoms get triggered including an increase in stress hormones, increased heartbeats, raised blood sugar level, and sweating and tensing of muscles. These symptoms are part of the “fight or flight” response. - Which part of the nervous system gets activated during such stressful situations?
A. Sympathetic nervous system
B. Parasympathetic nervous system
C. Both sympathetic and parasympathetic nervous systems
D. First the parasympathetic followed by the sympathetic nervous system
E. The “fight or flight” response is controlled by the endocrine system only.
The autonomic nervous system (ANS) is a major pathway activated by stress. The Sympathetic nervous system (SNS) is a part of ANS which contributes to the stress hormone secretion. Thus, A is the correct option.
What is Stress Hormone?Stress Hormone is also known as the hormone of fight or flight. Adrenaline also known as epinephrine is the stress hormone. This hormone is secreted from the Sympathetic Nervous System (SNS).
The hormone controls various physiological reactions like heartbeat, blood flow, blood sugar level, sweating, and muscle tension. It is secreted in response to attack, exciting condition or threat to survival.

You start with 100 units of protein activity and 100 grams of total protein. After the first centrifugation step, you have 15% less activity and 80% less total protein. What is your fold-purification of the target protein?.
We have 4.25 fold-purification of target protein.
Protein purification is a set of procedures designed to separate one or more proteins from a complicated mixture, often cells, organs, or whole organisms. Protein purification is essential for determining the function, structure, and relationships of a protein of interest. The number of times a protein preparation is enriched for the protein being purified is referred to as fold purification. If a protein concentration is 2nM before purification and 20nM after purification, the fold purification is twenty-fold.
Initial protein activity = 100 units
% change in protein activity = 15%
Final protein activity = 85%
Initial total protein = 100 grams
% change in total protein =80%
Final total protein = 20%
Fold purification = final protein activity / total protein

What is cardiac output?
The method via which blood circulates throughout the body, particularly supplying the brain and other vital organs with blood flow, is known as cardiac output (CO), or the volume of blood the heart pumps each minute. For instance, when exercising, the body's need for oxygen varies, and cardiac output is impacted by changes in both heart rate (HR) and stroke volume (SV). As a result, the complex mechanism that regulates cardiac output involves the autonomic nervous system, endocrine, and paracrine signaling pathways.
