Functions in Immunity or Protection: Alveolar macrophages, Alveolar surface area, Tonsils, C-rings, Nasal cartilage, Vibrissae.
Alveolar macrophages are involved in the immune response by engulfing and digesting pathogens in the alveoli of the lungs.
The high alveolar surface area provides a large area for gas exchange but also allows for the trapping and removal of inhaled particles and microorganisms by alveolar macrophages.
Tonsils are lymphatic tissue that helps protect against infections by trapping and removing bacteria and viruses that enter the body through the nose and mouth.
C-rings and nasal cartilage provide structural support to the trachea and nasal passages, respectively, and help prevent the collapse of these structures during breathing.
Vibrissae, or nose hairs, filter out large particles from inhaled air, preventing them from reaching the lungs.
Functions in Respiration: Compartmentalization, Surfactant, Mucociliary escalator, Cilia.
Compartmentalization of the lungs into smaller bronchioles and alveoli helps increase surface area for gas exchange and facilitates efficient oxygenation of the blood.
Surfactant is a substance that reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining efficient gas exchange.
Mucociliary escalator is a mechanism by which mucus and trapped particles are swept upward by the cilia lining the respiratory tract, allowing for their removal from the body.
Cilia also play a role in moving mucus and particles up and out of the respiratory tract, and they help protect against infection by removing pathogens from the airways.

in malaria, plasmodium falciparum grow inside human cells. because they use the human cells for food, they are classified as which of the following?
It is classified as an obligate intracellular parasite, which means that it requires a host cell to survive and reproduce.
Plasmodium falciparum is a type of protozoan parasite that causes malaria in humans. In the case of P. falciparum, the parasite grows and multiplies inside human red blood cells, using the cell's resources for its own nutrition and replication.
This process causes damage to the host cell and contributes to the symptoms of malaria, including fever, anemia, and organ failure. By classifying P. falciparum as an obligate intracellular parasite, we can better understand how it interacts with the human body and how it can be targeted by antimalarial drugs or vaccines.

Research on social ______ suggests that performance ________when novel tasks are performed in the presence of others. a.facilitation; improvesc.loafing; improvesb.facilitation; suffersd.loafing; suffers
Research on social facilitation suggests that performance improves when novel tasks are performed in the presence of others. Therefore, the correct option is: (a) 'facilitation; improves'.
Social facilitation is a phenomenon that happens when an individual performs better in the presence of others than they do when alone. Social facilitation was first described in 1898 when the presence of an audience was shown to enhance bicycle racers' performance. Later research, on the other hand, showed that this effect only applied to well-known or easy tasks.
When an individual is skilled in performing the job, the presence of others can lead to better performance. In contrast, when an individual is less experienced, it can lead to worse performance. Research on social facilitation began in the early 1900s with psychologists investigating the impact of the presence of others on simple tasks, such as working on a puzzle.
The original findings of Triplett (1898) led to a substantial amount of research, with the majority of the research in the area focusing on the impact of the audience on performance. However, over the years, various experiments conducted by psychologists led to the conclusion that social facilitation can be attributed to the strength of dominant responses, i.e. when we are in the presence of others, our dominant response tends to be more powerful than in solitude. Therefore, the correct option is: (a) 'facilitation; improves'.

When citrate is shuttled out of the mitochondria for fatty acid synthesis, the initial reaction by citrate lyase generates which of the following products?
a. Citrate and oxaloacetate
b. Pyruvate and malate
c. Acetyl-CoA and oxaloacetate
d. Acetyl-CoA and citrate
The correct answer is (c). The citrate lyase enzyme is involved in the generation of acetyl-CoA and oxaloacetate when citrate is shuttled out of the mitochondria for fatty acid synthesis.
Acetyl-CoA and oxaloacetate are produced as products by the initial reaction of citrate lyase. Citrate lyase is an enzyme that is responsible for the cleavage of citrate, producing acetyl-CoA and oxaloacetate. Citrate is produced in the tricarboxylic acid cycle in the mitochondria and is then transported to the cytoplasm where it is used in the synthesis of fatty acids.
The citrate lyase enzyme is a key regulator of fatty acid biosynthesis because it is responsible for the production of acetyl-CoA, which is a precursor to fatty acid biosynthesis. In the cytoplasm, acetyl-CoA is used to produce malonyl-CoA, which is then used to initiate fatty acid synthesis.
Therefore, when citrate is shuttled out of the mitochondria for fatty acid synthesis, the initial reaction by citrate lyase generates acetyl-CoA and oxaloacetate as products. The oxaloacetate can then be converted to pyruvate, which can then be used in the citric acid cycle to generate more acetyl-CoA.

The parasympathetic innervation of the heart occurs via cranial nerve (CN) X, also known as the vagus nerve.
The vagus nerve is the longest cranial nerve, and it carries parasympathetic fibers from the brain stem to the thoracic and abdominal viscera. It is part of the parasympathetic nervous system, which helps to regulate involuntary processes such as digestion and heart rate. Specifically, the vagus nerve carries parasympathetic fibers to the sinoatrial node of the heart, allowing it to slow the heart rate by stimulating the release of acetylcholine.
The vagus nerve is part of the parasympathetic nervous system, which is also known as the rest-and-digest system. It is responsible for slowing the heart rate, dilating blood vessels, stimulating digestive activity, and other involuntary processes. The parasympathetic nervous system is activated in response to restful or calming situations, and its primary purpose is to conserve energy.
In summary, the parasympathetic innervation of the heart occurs via cranial nerve X (the vagus nerve). The vagus nerve is part of the parasympathetic nervous system, which is activated in response to restful or calming situations. It carries parasympathetic fibers to the sinoatrial node of the heart, allowing it to slow the heart rate by stimulating the release of acetylcholine.
