Hello. This question is incomplete. The complete question would be:
"Which of these is an uncontrollable risk factors for disease? A. Nutrition B. Insect bites C. Hygiene D. Genetic
"
Answer:
D. Genetic
Explanation:
Some diseases, disorders, and other health problems are passed genetically from parents to children. This is uncontrollable as we cannot predict what will be inherited and there is no possibility of modifying the DNA. For this reason, we can consider that genetics is an uncontrollable risk factor for the disease, as it cannot control the genetic inheritance we will receive from our parents.
On the other hand, nutrition, insect bites and hygiene are manageable factors that can influence or limit the incidence of disease.
Explanation:Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
