Final answer:

PTH is produced by the chief cells of the parathyroid glands and regulates blood calcium levels by influencing calcium reabsorption in the kidneys and bone dynamics.

Explanation:

The parathyroid glands are responsible for the production of parathyroid hormone (PTH), which plays a crucial role in regulating blood calcium concentrations. PTH is produced by the chief cells located within these glands. When blood calcium levels fall below normal, PTH is secreted to increase the calcium levels by enhancing calcium reabsorption in the kidneys, stimulating osteoclast activity (which releases calcium from bones), and promoting the synthesis of calcitriol, which aids in dietary calcium absorption from the digestive system.

These functions of PTH maintain homeostatic calcium levels in the body.

Answer: Diuretics and beta-blockers

Explanation:

Hypertension is a condition in which high blood pressure occurs. In this condition the pressure of the blood inside the arteries is severely elevated. The blood exerts force on the walls of the arteries.

Following are the medications which can be used for the treatment of high blood pressure.

1. Diuretics: These medicines helps to reduce the excess level of sodium and water and hence it regulates the blood pressure. It is used along with other therapies.

2. Beta-blockers: These are the medicines which help in reducing the heart rate hence, helps in lowering blood pressure.

Answer: Anti-adrenergics and Diuretics

Explanation:

Doctors do not prescribe medication until the patients's blood pressure reaches 160/100, below this the hypertension is considered as mild hypertension.

For the people who is already suffering from diabetes and kidney disease, medications will be use at 130/80.

Diuretics are commonly known as water pills. These work by helping the kidney to eliminate sodium and water out of the body. This process decreases decreases the volume of blood and the heart needs to less pump with each beat, which lowers the blood pressure of the body.

Anti-adrenergics are another class of drugs that is offered to the patients suffering from the problem of hypertension. These drugs lowers the blood pressure by limiting the action of the hormone epinephrine and norepinephrine, which relaxes the blood vessels which reduces the spped of heart's contractions.

Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli. False. In ventilation perfusion coupling, the goal is to match airflow and blood flow for optimal gas exchange in the lungs. However, there may be variations in blood flow and ventilation.

Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli. False. Ventilation refers to the movement of air into and out of the lungs, while perfusion refers to the blood flow to the lungs. In the context of ventilation perfusion coupling, the goal is to match the airflow and blood flow to optimize gas exchange in the lungs. Ideally, blood flow would be directed towards functional alveoli, where there is adequate ventilation. However, in reality, there may be variations in blood flow and ventilation, resulting in some blood flowing past nonfunctional alveoli as well.

Ventilation perfusion coupling is a crucial process that matches the flow of air and blood in our lungs. It optimizes the efficiency of oxygen uptake and carbon dioxide removal by directing more blood past well-ventilated (functional) alveoli and less past poorly ventilated (non-functional) alveoli.

The statement about ventilation perfusion coupling is indeed true. Ventilation perfusion coupling is a mechanism by which the body ensures efficient gas exchange in the lungs by matching ventilation and blood flow. When ventilation is sufficient, the partial pressure of oxygen in the alveoli remains high. If ventilation is insufficient, the body constricts the pulmonary arteriole serving the affected alveolus, which redirects blood flow towards alveoli with sufficient ventilation. Meanwhile, pulmonary arterioles serving well-ventilated alveoli dilate, allowing more blood flow. This process enhances the overall efficiency of oxygen transport and carbon dioxide removal, ensuring more blood flows past functional alveoli than past nonfunctional alveoli.

Answer:

Cancer cells lack contact inhibition; therefore, they do not stop reproducing

Explanation:

Answer:

The Hardy-Weinberg equation is written as p²+q²+2pq = 1 and p + q =1

where,

p² is the frequency of homozygous dominant (BB)

q² is the frequency of homozygous recessive (bb)

2pq is the frequency of heterozygous (Bb)

p is the frequency of dominant allele (B)

q is the frequency of recessive allele (b)

As per given details, the number of homozygous recessive organisms in a population is 76.

Total population size is 5468

Thus, the frequency of homozygous recessive (q²) = [tex]\frac{76}{5468}[/tex]

⇒ q² = 0.014

⇒q = [tex]\sqrt{0.014}[/tex]

⇒q = 0.118

∴ p = 1 - 0.118

⇒p = 0.882

thus, the frequency of yellow fat allele is 0.118 and that of white fat allele is 0.882

Answer:

Muscularis externa layer.

Explanation:

The muscularis externa layer lies adjacent to the submucosa membrane. This is the third layer of the gastro intestinal tract. The muscularis externa of the colon is thick as it carries and passes urine and feces.

Muscularis externa layer prevents the backward travelling of food. This layer is mainly responsible for the peristalsis movement of food in the gastro intestinal tract and responsible for the segmentation as well.

The muscularis externa, a layer in the alimentary canal, is responsible for both segmentation (mixing) and peristalsis (propulsion) of food through rhythmic muscle contractions, facilitating digestion and nutrient absorption.

The muscular layer of the alimentary canal, known as the "muscularis externa," is responsible for both segmentation and peristalsis. Peristalsis is the coordinated, rhythmic contraction and relaxation of the smooth muscle in the muscularis externa that propels food through the digestive tract, while segmentation involves the mixing and churning of food to facilitate digestion and absorption.

These muscular movements are essential for moving food through the digestive system and breaking it down into smaller particles for nutrient absorption.

Somatic and autonomic nervous system

Explanation:

It consists of somatic nervous system and autonomic nervous system

Final answer:

The peripheral nervous system (PNS) is comprised of nerves that connect the central nervous system to the rest of the body, facilitating communication between the brain, limbs, and organs. It has two main subdivisions: the somatic and the autonomic systems and is further divided into sensory and motor divisions.

Explanation:

The peripheral nervous system (PNS) is an essential component of the human nervous system. It comprises a network of nerves that extend from the central nervous system (CNS), which includes the brain and spinal cord, to various parts of the body. The PNS is responsible for connecting the CNS to limbs and organs, essentially serving as a communication relay back and forth between the brain and the extremities. It is made up of thick bundles of axons, known as nerves, which carry messages between the CNS and the muscles, organs, and sensory systems in the periphery of the body.

The PNS has two primary subdivisions: the somatic nervous system and the autonomic nervous system. The somatic nervous system is concerned with conscious perception and voluntary motor responses, while the autonomic nervous system controls involuntary functions such as heart rate and digestion.

The PNS is also divided into sensory and motor divisions. The sensory division is responsible for transmitting sensory information to the CNS, and the motor division is involved in transmitting motor commands from the CNS to the rest of the body.

Answer:

d. Hemoglobin helps maintain a constant pH in the blood by binding with H⁺ions released from bicarbonate ions.

Explanation:

The presence (CO₂) in in the erythrocytes lowers its pH as a result the affinity of hemoglobin decreases for oxygen. The carbon dioxide (CO₂) reacts with water to form carbonic acid in the presence of the enzyme carbonic anhydrase which is present in the erythrocytes or red blood cells. The carbonic acid then changes into two ions hydrogen ion (H⁺) and bicarbonate ion (HCO₃⁻).  As a result of H⁺ ions, the pH of blood drops. Haemoglobin pick up hydrogen ions to balance the decrease in pH. Thus, haemoglobin helps in maintaining constant pH or keep pH of blood in buffer.

Answer: To meet the demand of more oxygen by the body.

Explanation: During the time of exercise the need for oxygen by the body increases. The minute ventilation of an individual will increase due to increase in the tidal volume and frequency of breathing.

The extra space is provided by the inspiratory reserve volume which acts as a reservoir of extra lung volume that can become inflated with air and as we need it.

So, Inspiratory reserve volume and expiratory reserve volume decreases during heavy exercise as there is a need of more inhalation of oxygen and more exhalation of carbon dioxide as tidal volume increases and cover the space.

Final answer:

During heavy exercise, the need for increased oxygen uptake and carbon dioxide expulsion results in greater tidal volume usage and a deeper, more forceful exhalation, thus reducing ERV and IRV. Blood flow redistribution and an elevated cardiac output further limit these respiratory reserve volumes to prioritize metabolic needs over maximum lung ventilation capacity.

Explanation:

The question relates to why the Expiratory Reserve Volume (ERV) and Inspiratory Reserve Volume (IRV) are lower during heavy exercise compared to moderate exercise. Physiologically, during heavy exercise, there is an increased demand for oxygen and an increased production of carbon dioxide. This necessitates a higher rate of ventilation to facilitate gas exchange. As a result, the tidal volume (the volume of air inhaled and exhaled in a single breath) increases, utilizing a greater portion of the IRV. Simultaneously, to maximize the expulsion of CO2, individuals exhale more forcefully and deeply, reducing the ERV. This adjustment allows for the optimization of oxygen intake and carbon dioxide expulsion, which is crucial during periods of intense physical activity.

Another critical factor is the redistribution of blood flow during intense exercise. There is an increased blood supply to the working muscles and skin to support metabolic processes and heat dissipation, respectively. This hemodynamic adjustment further compromises the capacity for large IRV and ERV as the body prioritizes oxygen and nutrient delivery to the muscles over maximum pulmonary ventilation reserve capacities.

Lastly, the cardiovascular response to exercise, including increased heart rate and stroke volume, contributes to a heightened cardiac output. This enhanced cardiac activity supports the increased metabolic demands of heavy exercise but can limit the thoracic capacity for large expansions and contractions of the lungs, thereby decreasing the IRV and ERV.

The impact on the human health as we try to stay ahead of the evolutionary process is actually very bad. It is a fact that the humans are living much longer nowadays than ever before, with the main reasons for that being the well developed medicine and healthcare, much better standard of living, and having less riskier jobs. On the other hand, the human health, without being treated, is actually at an all time low. The immune system is much weaker than it has been, with the main reason being the isolation of the outside world and the higher level of hygiene. The allergies are becoming an ever growing problem because of this, as the immune system doesn't even recognize certain outside bodies are they an enemies or not. The constant radiation for numerous sources has caused development of numerous diseases. The old age has increased the percentage of diseases such as cancer, Alzheimer, Parkinson, or sclerosis.

Answer:

Explanation:

The central nervous system (CNS) does not have capacity to repair itself but, the PNS or the peripheral nervous system can repair and regenerate itself. The PNS can regenerate its damaged axon only when its cell body or cyton and its neurilemma are intact. The proximal end of the cyton has growth cones. The axon grows from the cones.    

The cell body or soma of a neuron is crucial for axon regeneration because it is the site of protein synthesis and energy production, which are necessary for the rebuilding of the axon and its myelin sheath. The myelin sheath allows for efficient signal transmission along the axon and requires proteins produced in the soma for its structure and function. New research involving intracellular signal peptide (ISP) shows promising results for supporting nerve regeneration.

The cell body of a neuron, or its soma, is the central part of the neuron that contains the nucleus. This part of the cell is critical for its survival and function. It is in the cell body where all the protein synthesis and energy production necessary for the neuron to function takes place. Somas produce the proteins that are necessary for the structure and function of the axon and its myelin sheath.

The myelin sheath, made by Schwann cells in the Peripheral Nervous System (PNS), is critical to the functioning of the axon. It acts as an insulator for the axon, allowing electrical signals to travel down the axon in a rapid and efficient manner. This is through a process known as saltatory conduction, where the signal jumps between gaps in the myelin called Nodes of Ranvier.

When an axon is damaged, the cell body is necessary to orchestrate the rebuilding of the myelin and the axon. If the cell body is not intact, these processes cannot occur, hence preventing regeneration. Recent scientific research has shown promise for supporting the regeneration process through a drug called intracellular signal peptide (ISP), potentially offering new avenues for nerve healing in the future.

Answer:

Co-transport.

Explanation:

Co-transport may be defined as the process of transport of two molecules across the membrane without the use of energy. Two types of co transport are symport and antiport.

The bacteria transport system import phosphate into the cell. The import of the phosphate depends on pH. Since, the import of phosphate depends on pH and does not depend on the ATPase activity. Here, the phosphate molecules can simultaneously cross the membranes.

Thus, the answer is co-transport.

In bacteria, the phosphate transport system that functions despite a lower external phosphate concentration and relies on a pH gradient is an example of active transport, which uses energy to move substances against their concentration gradient.

The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration. When phosphate import depends on a pH gradient across the membrane—more acidic outside the cell than inside the cell—this process is an example of active transport.

Active transport requires energy to move substances across a membrane, typically against their concentration gradient. Examples of active transport mechanisms include the sodium-potassium pump, which exchanges sodium for potassium ions against their respective concentration gradients using ATP. Similarly, phosphate is transported into bacterial cells against its gradient, facilitated by a pH difference, and this process too may utilize energy in the form of ATP or other couplings with primary active transport mechanisms.

In some cases, substances are modified during the import process as seen in group translocation, which also contributes to the energy-neutral import of substances like sugars via the phosphotransferase system. Nonetheless, the essential characteristic of active transport is the use of energy to accomplish the movement of substances across cell membranes.

Allosteric enzymes, often multisubunit proteins, can exhibit homoallostery and heteroallostery. There is, however, a difference in the binding curve for a cooperative binding versus a noncooperative binding enzyme.

Allosteric enzymes are indeed often multisubunit proteins that have multiple active sites. They can exhibit homoallostery, where they show cooperativity in substrate binding. This means that the binding of one substrate molecule to one active site increases the affinity of the rest of the active sites for the same substrate.

Allosteric enzymes also exhibit heteroallostery, meaning, their activity can be regulated by other effector molecules binding to a site other than the active site. Effectors can be either inhibitors or activators that decrease or increase the enzyme's activity respectively.

However, it's not accurate to say there is no difference in the binding curve for a cooperative binding versus noncooperative binding enzyme. The binding curve for allosteric enzymes (cooperative binding) is sigmoidal, while for non-allosteric enzymes (noncooperative binding), it is hyperbolic.

These enzymes are often multisubunit proteins, with multiple active sites that can be influenced by effector molecules.

The statements about allosteric enzymes given by the student consist of several true points. Allosteric enzymes do indeed exhibit cooperativity in substrate binding (also known as homoallostery), which means that the binding of a substrate molecule to one active site on the enzyme can enhance the binding of more substrate molecules to other active sites. Furthermore, allosteric enzymes can be regulated by effector molecules (referred to as heteroallostery), which can either inhibit or activate the enzyme.

However, there is a distinction in the binding curve for allosteric enzymes with cooperative versus noncooperative binding; cooperative binding often results in a sigmoidal (or S-shaped) enzyme kinetics curve, whilst noncooperative binding usually produces a hyperbolic curve. Also, allosteric enzymes are often multisubunit proteins, meaning they are composed of more than one polypeptide chain and possess multiple active sites. These active sites can be influenced by the binding of effector molecules, leading to changes in the enzyme's activity.
