Answer: C. Chagas disease
Explanation:
Xenodiagnosis is a method of diagnosis and detection of the microorganism responsible for infecting the tissues of the body. 
Chagas disease is a potentially life threatening disease. It is caused by the protozoan parasite called as Trypanosoma cruzi. It is transmitted to people through the feces of insects. This disease is common in South and Central America and in Mexico. The xenodiagnosis is used to detect the parasite responsible for the Chagas disease.

Answer:
c. More oxygen and less carbon dioxide 
Explanation:
The composition of air in the layers between the soil is called soil atmosphere or gas.
The maximum percentage of gas in soil is nitrogen with 79.2 %. Then it is oxygen with 20.6 % and the last is carbon dioxide with 0.25 %. These gases are required in order to maintain life under the ground. The roots of trees and the microorganisms require soil atmosphere to carry out their functions.

Answer:
Slow-twitch
Explanation:
Red meat is rich in slow-twitch muscle fibers. The slow-twitch muscle fibers are rich in myoglobin and blood capillaries. They also have many large mitochondria to generate ATP by aerobic respiration. 
These fibers are slow-twitch fibers as the ATPase in myosin head carries out the hydrolysis of ATP at a slower rate causing a slower contraction cycle. 
Slow-twitch fibers appear red due to a large amount of myoglobin and a rich network of blood vessels. They are capable of prolonged contractions and are fatigue resistant.
