Answer:
El conocimiento del ADN, su estructura y función, fue determinante para el desarrollo de la biotecnología moderna. ... Es decir que el ADN de un ser humano puede ser “leído” dentro de una bacteria, y una planta puede interpretar la información genética de otra planta diferente.
Explanation:
<span>Peter Raymond Grant, FRS, FRSC, and Barbara Rosemary Grant, FRS, FRSC, are a British couple who are evolutionary biologists at Princeton University. Each currently holds the position of emeritus professor. They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of years. Charles Darwin originally thought that natural selection was a long, drawn out process. The Grants have shown that these changes in populations can happen very quickly.</span>
As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion.Mar 4, 2016
<span>The bite of an infected ticks. The disease, caused by bacteria of the borrelia type, is transmitted to humans through the bite of infected ticks of the Ixodes genus. Two tick species the black legged tick and the western blacklegged tick are known to transmit the bacterium. Most humans are infected from the bites of immature ticks (nymphs) because adult with Borrelia burgdorferi bacterium are larger and more likely to be discovered.</span>
Macrophages are immune cells which are responsible for performing the functions like clearance of pus, cellular debris, dead neutrophils as well as damaged tissue after the inflammation has been performed.
Macrophages are a type of immune cells. They are large phagocytic cells which can be found either mobile as a white blood cell or they can also be found in a stationary form in the tissues. They can especially be found at the site of infection.
During inflammation, they enter about 72 hours post the initial response to perform the function of cleaning up the debris, pus and also the dead neutrophils.
