I think it’s c idrk so double check the answer
The answer to this question would be: impaired gas exchange.
<span>Pneumocystis jiroveci attack the lungs and cause pneumonia. Pneumonia will reduce the lungs function and might cause dyspnea or even respiratory distress in severe cases. The ulcer in the feet wouldn't kill the patient but respiratory distress would.</span>
Answer:
1. The oxygen deprived cardiac muscles caused chest pain.
2. Unavailability of oxygen and blood supply to skin cells made them pale and cold.
3. Accumulation of blood in pulmonary circuit caused moist sounds.
Explanation:
The left ventricle receives oxygenated blood from the left atrium. Oxygenated blood from the lungs is carried to the left atrium by pulmonary veins. The left ventricle pumps the oxygenated blood to all body parts through the aorta. Failure of the left ventricle deprived the skin cells of oxygenated blood. Oxygen deficiency stopped energy production by cellular respiration. The result was pale and cold skin.
Failure of the left ventricle led to the accumulation of blood in the pulmonary circuit since the blood was not delivered to body tissues. The build-up of blood and resultant higher blood pressure caused moist sounds in the lower lungs.
The blockage of the coronary artery by a blood clot and death of a part of the heart due to lack of oxygen leads to a heart attack. The dead heart tissue is known as infarct and the resultant heart attack is myocardial infarction. Chest pain is caused due to the dead heart tissue or infarct.
Answer:
C. If microbes can live in toxic arsenic, they have evolved.
Explanation:
After reading the chapter "Earthbound Extraterrestrial? Or Just Another Microbe in the Mud?" We can conclude that if microbes can live in toxic arsenic, they have evolved. This is because toxic arsenic is not a favorable environment for any living thing. Living conditions in a toxic arsenic environment are very inhospitable for the development of microorganisms that are able to survive under these environmental conditions. However, some microorganisms can survive and reproduce more microorganisms with the same survivability. This process indicates that these microorganisms have evolved since this new generation has a feature that the past generation did not have.
Fossil Z is younger than fossil Y
