Glomerulonephritis is an inflammation of the glomeruli, the tiny filters in the kidneys responsible for removing waste and excess fluid from the blood.                                                                                                                                  

Glomerulonephritis is a kidney disease that can occur as a result of various triggers, including bacterial infections. Bacteria, such as streptococcus, can cause an immune response in the body that damages the glomeruli - the tiny blood vessels in the kidneys. This damage can lead to inflammation and impair the kidneys' ability to filter waste and excess fluids from the blood.
When the immune system fights the bacterial infection, it can inadvertently cause damage to the glomeruli, leading to glomerulonephritis. This condition can impact kidney function and, if left untreated, may result in chronic kidney disease or even kidney failure. Prompt medical treatment is crucial to managing the condition and preventing complications.

In order to better understand the evolutionary relationships of the organisms that produced the fossils, the substances that biochemists often look for in fossils are embryology, molecular biology, and their geographic distribution.

Fossils are the remains of organisms that provide strong evidence of evolution. Scientists determine the generality of the fossils found from the age of the rock layers as well as carbon dating. Fossils are also studied to determine their relationship to one another.

Apart from fossils, other clues about evolution are anatomy and embryology. Anatomy shows the existence of homologous organs and analogous organs in living things. Homologous organs show that living things from the same ancestor developed organs with different functions. The clue to evolution in embryology is the similarities between the embryos.

Yes, Homo sapiens (modern humans) are associated with the broad spectrum revolution, which refers to a significant shift in subsistence strategies towards a wider range of plant and animal resources.

The broad spectrum revolution is a term used in archaeology and anthropology to describe a major change in human subsistence patterns that occurred during the transition from hunter-gatherer societies to settled agricultural communities. This revolution is characterized by a significant increase in the variety of plant and animal species utilized for food and other resources.

Homo sapiens, as the species to which modern humans belong, played a crucial role in this revolution. It is believed that our ancestors, through their cognitive abilities, technological innovations, and social adaptations, gradually expanded their diet to include a broader range of resources beyond traditional hunting and gathering. This included the deliberate cultivation of plants and the domestication of animals, leading to the development of agriculture and pastoralism.

The broad spectrum revolution marked a significant milestone in human history, as it provided increased stability and food security, leading to the establishment of permanent settlements and the emergence of complex societies. It also had profound impacts on human biology, social organization, and cultural development, setting the stage for the subsequent advancements in human civilization.

Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are found in the domains Bacteria and Archaea.

There are many components present in prokaryotic organisms. Some of them are discussed below:

Cell wall: This is a tough, protective layer that surrounds the cell membrane in bacteria and archaea. The cell wall is made up of peptidoglycan in bacteria and other materials in archaea.

Flagella: It is a whip-like structure that is used by many prokaryotic cells to move. The flagellum rotates like a propeller, allowing the cell to swim through liquid environments.

Pili or fimbriae: These are short, hair-like structures that extend from the surface of many prokaryotic cells. They are used for attachment to surfaces or other cells.

Capsule: It is a protective layer that surrounds the cell wall of some prokaryotic cells. The capsule is made up of a gel-like material that helps the cell to avoid being engulfed by immune cells such as macrophages.

Ribosomes: They are the site of protein synthesis in prokaryotic cells. Ribosomes are made up of two subunits that come together to form a functional ribosome.In conclusion, components that are present in prokaryotic organisms are cell wall, flagella, pili or fimbriae, capsule, and ribosomes.

The cells responsible for cleaning and digesting debris entering the alveoli are called alveolar macrophages.

Alveolar macrophages are specialized immune cells found in the alveoli, which are the tiny air sacs in the lungs where gas exchange takes place. These cells play a crucial role in the respiratory defence system by actively removing and digesting debris, particles, and pathogens that enter the alveoli during inhalation.

When foreign particles, such as dust, pollen, or bacteria, are inhaled, they can reach the alveoli. Alveolar macrophages are strategically positioned within the alveolar spaces to encounter and engulf these particles. They possess specialized receptors on their surface that allow them to recognize and bind to foreign substances.

Genetic variation is necessary for evolution by natural selection because it (A) results in different traits which can be selected for or against.

Explanation:

Natural selection is a process in which organisms with certain traits are more likely to survive and reproduce, while those with less advantageous traits are less likely to survive and reproduce. This results in the survival of the fittest and the evolution of new species over time. Without genetic variation, there would be no differences in traits and therefore no way for natural selection to occur.

In response to c. acid in duodenum, the hormone secretin is released by endocrine cells in the duodenal mucosa.

Secretin is a polypeptide that contains 27 amino acids. In response to H+ and fatty acids in the lumen, S cells in the duodenum produce secretin. Particularly, a pH of less than 4.5 indicates the entry of stomach contents, which starts the secretin release.

Secretin, a digestive hormone that controls gastric acid secretion and pH levels in the duodenum, is released by the wall of the upper portion of the small intestine (the duodenum).

A pancreatic fluid that is high in bicarbonate is secreted when secretin is present (45). By interacting with pancreatic ductal cells, secretin enters the bloodstream or intestinal lumen and increases the production of bicarbonate, which lowers the pH of the gastric chyme as it enters the small intestine.
