An error in transcription/translation affects only one cell.
An error in DNA replication would affect many generations of cells.
Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.
When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.
If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.
Answer:
Les alvéoles pulmonaires sont situées au plus profond des poumons, aux extrémités des bronchioles, et sont la structure de base où se réalisent les échanges gazeux entre l'organisme et l'air extérieur.
