Answer:
C. 3 indirect transmissions
Explanation:
In epidemiology, direct transmission is considered to occur when an individual has direct contact with a pathogen, which infects him and develops a disease. Indirect infections, on the other hand, occur when individuals come into contact with the pathogen through a transmission vehicle.
In this case, we can conclude that in the question above, there were 3 cases of indirect transmission. This is because all people who had contact with the pathogen, established that contact through the contaminated marker. In this case, the marker is a transmission vehicle.
Answer:
Because mRNA tells you what type of veins
Explanation:
These cells are also characterized by having no nucleus, being devoid of organelles. So no organelles are missing from trevor's red cells.
<h3>What is Hereditary elliptocytosis?</h3>
Hereditary spherocytosis and elliptocytosis are congenital disorders of the erythrocyte membranes that cause mild hemolytic anemia. Symptoms, usually milder in hereditary elliptocytosis, include varying degrees of
- Anemia
- Jaundice
- and Splenomegaly.
Diagnosis requires demonstration of increased osmotic fragility of erythrocytes and a negative direct antiglobulin test. Rarely, patients < 45 years of age with symptomatic disease require splenectomy.
With this information, we can conclude that the red cells of Trevor do not have organelles, a fact that is not altered by their condition (Hereditary elliptocytosis).

The correct answer is D: Group 4.
A control group in an experiment is a group separated from the other groups, where the variable that is being tested cannot influence the results. In this case, different materials are the independent variable that you test. Effects of that independent variable on the melting rate of ice are excluded in the control group.
