The question that needs more information is the first one, which asks about the significance of immune pathology using influenza and why current treatment (Tamiflu) against it aren't effective.What is immune pathology?Immune pathology is a branch of medicine that studies immune system disorders that may affect people of all ages. It also looks at the pathogenesis of the immune system's response to different diseases.
What is Influenza?
Influenza is a viral illness that is highly contagious. It spreads quickly from one person to another via respiratory droplets. The virus mutates regularly, making it difficult to prevent it.
As a result, influenza is a significant public health concern worldwide.
Various drugs are available to treat influenza, but neuraminidase inhibitors such as Tamiflu are ineffective because the virus is developing resistance to these drugs.
As a result, new and more effective treatments are needed.What makes the children and elderly more vulnerable to virus infections?The elderly are more vulnerable to viral infections because their immune systems become less effective with age, making it more difficult for their bodies to resist infections.
Furthermore, many older adults have pre-existing medical problems that may affect their immune system.
Children, on the other hand, have immature immune systems, making them more susceptible to viral infections. Additionally, their contact with others in schools and day-care centers increases their risk of exposure to viral infections.
They are also more prone to asthma and other underlying conditions that increase their vulnerability to viral infections.

T helper lymphocytes recognize antigens presented by a. MHC 1 molecules on antigen presenting cells b. MHC I molecules on all nucleated cells c. MHC II molecules on all antigen presenting cells d. MHC I molecules on all red blood cells
T helper lymphocytes recognize antigens presented by MHC II molecules on all antigen-presenting cells. The correct option is C MHC II molecules on all antigen-presenting cells.
T helper lymphocytes, also known as CD4+ T cells, are a type of immune cell that plays a crucial role in the immune response. They recognize antigens, which are foreign substances or molecules, presented by major histocompatibility complex class II (MHC II) molecules on antigen-presenting cells.
MHC II molecules are proteins found on the surface of specialized cells called antigen-presenting cells (APCs), which include dendritic cells, macrophages, and B cells. These cells capture the process, and present antigens to T cells for recognition. When a pathogen or foreign substance enters the body, APCs engulf and break it down into smaller fragments. These fragments are then loaded onto MHC II molecules and presented on the surface of the APCs.
T helper lymphocytes have specific receptors called T cell receptors (TCRs) that can recognize the antigens presented by MHC II molecules. When a TCR on a T helper cell encounters an antigen-MHC II complex that matches its receptor, it triggers a series of immune responses, including the activation of other immune cells and the production of specific immune molecules.
Therefore, the correct statement is that T helper lymphocytes recognize antigens presented by MHC II molecules on all antigen-presenting cells.

2. What molecule(s) make bones flexible? 3. What molecule(s) make bones hard? 4. What are the similarities and differences between osteocytes, osteoblasts and osteoclasts? How do these cells function in bone remodeling?
Collagen molecules make bones flexible. Collagen is a protein fiber that accounts for roughly one-third of bone tissue and is responsible for its pliability.
Collagen, in particular, gives bone its tensile strength, which is essential for its ability to withstand tensile and torsion stress. Collagen, on the other hand, isn't very stiff, and it has little resistance to compression, bending, or shear. Calcium phosphate (Hydroxyapatite) molecules make bones hard. Calcium phosphate and hydroxyapatite crystals are found in bones and give them their hardness. Hydroxyapatite is a mineral that accounts for 70% of bone volume and is primarily responsible for bone hardness.
Osteocytes, osteoblasts, and osteoclasts are all important bone cells that are crucial for bone remodeling. Osteocytes are cells that are surrounded by bone tissue and are derived from osteoblasts. They are responsible for maintaining bone density and strength by signaling the bone-forming osteoblasts to begin bone deposition and the bone-dissolving osteoclasts to stop bone resorption.
Osteoblasts are bone-building cells that synthesize and secrete collagen and other proteins, which they deposit in the bone matrix. They play an important role in bone development, repair, and remodeling by forming new bone tissue.
Osteoclasts, on the other hand, are bone-resorbing cells that dissolve bone tissue. They are involved in the breakdown of bone tissue during bone remodeling and are critical for calcium and phosphate homeostasis. They secrete hydrogen ions and proteolytic enzymes, which dissolve the bone matrix.
The three cell types work together to maintain healthy bones by maintaining a balance between bone deposition and resorption. Osteoblasts form new bone tissue, while osteoclasts resorb or remove old bone tissue. Osteocytes maintain bone density by regulating the activity of osteoblasts and osteoclasts.

Pyrimidine nucleotides are important nitrogen-containing
compounds. Outline how pyrimidines are synthesised in the cell,
including the role of amino acids as precursors in this
process.
Pyrimidine nucleotides are synthesized in the cell through a multistep process, involving the incorporation of carbon and nitrogen atoms into a pyrimidine ring structure, with amino acids serving as precursors for nitrogen donation.
Pyrimidine nucleotides are synthesized through a multi-step process known as de novo synthesis. The synthesis of pyrimidines involves the incorporation of carbon and nitrogen atoms into a pyrimidine ring structure.
The first step of pyrimidine synthesis involves the formation of carbamoyl phosphate, which requires the enzyme carbamoyl phosphate synthetase II and utilizes glutamine as a nitrogen donor. The carbamoyl phosphate then reacts with aspartate to form a compound called carbamoyl aspartate, catalyzed by the enzyme aspartate transcarbamoylase.
Carbamoyl aspartate is then converted into dihydroorotate through a series of enzymatic reactions. Dihydroorotate is subsequently oxidized to form orotate, a key intermediate in pyrimidine synthesis.
Amino acids also play a role in pyrimidine synthesis. Aspartate, as mentioned earlier, is utilized to form carbamoyl aspartate. Additionally, glutamine contributes nitrogen for the formation of carbamoyl phosphate. Amino acids like glycine and glutamine are involved in the synthesis of other components of nucleotides, such as purines.

6. Describe the mechanics of breathing. 7. Describe oxygen transport in blood. 8. Describe carbon dioxide transport in blood.
The mechanics of breathing involve the process of inhalation and exhalation.
During inhalation, the diaphragm and intercostal muscles contract, expanding the thoracic cavity and reducing pressure, which allows air to enter the lungs. Exhalation occurs when the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in size, increasing pressure and forcing air out of the lungs.
Oxygen transport in blood occurs through the binding of oxygen molecules to hemoglobin, a protein found in red blood cells.
In the lungs, oxygen diffuses across the alveolar membrane into the capillaries, where it binds to hemoglobin and forms oxyhemoglobin. This oxyhemoglobin is then transported through the bloodstream to body tissues, where oxygen is released from hemoglobin and diffuses into the cells for cellular respiration.
Carbon dioxide transport in blood involves three main mechanisms.
The majority of carbon dioxide is carried in the form of bicarbonate ions, which are formed when carbon dioxide reacts with water in red blood cells. Some carbon dioxide binds to hemoglobin and is transported as carbaminohemoglobin. Additionally, a small amount of carbon dioxide dissolves directly in the plasma. Carbon dioxide is transported from body tissues back to the lungs, where it is eliminated during exhalation.

Compare a normal EKG with an abnormal one that indicates
tachycardia and explain how it can be used to diagnose the
condition. Explain the symptoms and treatment for that
condition.
A normal electrocardiogram (EKG) represents the electrical activity of the heart and typically shows a regular rhythm and specific waveforms. In contrast, an abnormal EKG indicating tachycardia would show a faster heart rate than the normal range (generally defined as a heart rate greater than 100 beats per minute).
To diagnose tachycardia based on an abnormal EKG, healthcare professionals look for specific EKG characteristics. These include a shortened PR interval (the time it takes for the electrical signal to travel from the atria to the ventricles), narrow QRS complexes (indicating that the electrical signal is originating from the normal conduction pathway), and a fast and regular rhythm.
Symptoms of tachycardia may include palpitations (rapid or irregular heartbeat sensations), shortness of breath, lightheadedness, dizziness, chest discomfort, and in severe cases, loss of consciousness or fainting. However, the symptoms can vary depending on the underlying cause and the individual's overall health.

Which of the following is a TRUE statement? (Check all that apply) a. During hemostasis, the platelets aggregation is characterized by a positive feedback loop. b. During hemostasis, aggregating platelets release serotonin and other products in a process called platelet lytic reaction. c. During hemostasis, ADP and thromboxane d. A both promote platelet aggregation and vasoconstriction With regards to hemostasis, prostacyclin and NO are antagonists to serotonin and thromboxane. e. CD39 specifically inhibits platelet aggregation. f. A fluid called plasma is formed during the process of clot retraction. g. Platelets contribute to secondary hemostasis by providing phospholipids and binding sites for fibrinogen and fibrin. h. Blood clotting in a test tube essentially involves the extrinsic pathwghmof secondary hemostasis i. The intrinsic pathway of secondary hemostasis is initiated by thromboplastin. j. Hydrophilic surfaces and negatively charged structures initiate the contact pathway of secondary hemostasis.
The correct statements are:
a. During hemostasis, the platelet aggregation is characterized by a positive feedback loop.
c. During hemostasis, ADP and thromboxane A2 both promote platelet aggregation and vasoconstriction.
g. Platelets contribute to secondary hemostasis by providing phospholipids and binding sites for fibrinogen and fibrin.
i. The intrinsic pathway of secondary hemostasis is initiated by thromboplastin.
During hemostasis, platelet aggregation is a crucial step in forming a stable blood clot. Platelets release various substances, including ADP and thromboxane A2, which promote platelet aggregation and vasoconstriction, enhancing the clotting process. This positive feedback loop amplifies platelet aggregation. Platelets also contribute to secondary hemostasis by providing phospholipids and binding sites for fibrinogen and fibrin, essential components for clot formation. The intrinsic pathway of secondary hemostasis is initiated by thromboplastin, not the extrinsic pathway. Therefore, options a, c, g, and i are the correct statements.

Viviana and Jessica go to the track together to train. Viviana is a weightlifter while Jessica is a spin class instructor. Viviana runs at a high intensity for 30 minutes; while Jessica jogs at a moderate intensity for 45 minutes. How long will it take Viviana and Jessica to completely recover? (Select one time for Viviana and one for Jessica) a. 1 hour b. 30 minutes c. 2 hours d. 45 minutes e. 24 hours
The correct option is B. 30 minutes .The recovery time for Viviana and Jessica after their respective workouts will vary based on individual factors such as fitness levels and personal recovery abilities.
Viviana, being a weightlifter and engaging in high-intensity exercise for 30 minutes, may experience a higher level of muscle fatigue and metabolic stress. It is common for weightlifters to require a longer recovery period compared to moderate-intensity exercises like jogging. Therefore, it is possible that Viviana may need a longer recovery time, potentially closer to 1 hour or even up to 24 hours, depending on the intensity of her workout and her individual recovery capacity.
Jessica, on the other hand, is engaging in a moderate-intensity jog for 45 minutes. While jogging can still cause fatigue and stress on the body, it is generally less intense compared to weightlifting. As a result, Jessica may require a shorter recovery time, potentially around 30 minutes to an hour, to replenish energy stores and allow her body to recover.
