The result of the cross of an intermediate plant (Tt) with a tall plant (TT), when the tall gene (T) is incompletely dominant over the short gene (t) will be as shown in the punnet square below. The gametes formed will be T , T , T, and t (Where T is the allele for tall while t is the allele for short).The punnet square shows that the 50 % of the progeny of this cross will be tall (TT), and the other 50% will be intermediate (Tt). Hence, the correct answer is 'Option C - 50 percent tall, 50 percent intermediate'.
Answer:b
Explanation:
Heterogeneous mixture because it is not chemically bound together
Answer:
List three protozoan infections of the circulatory system that are transmitted by arthropods:
Malaria
Toxoplasmosis
Chagas disease (American trypanosomiasis)
Explanation:
Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.
Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.
Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.
