5. Which task would be best accomplished in a field of engineering? A. Explaining how water travels up the tissues of a plant b. Predicting the outcome of mixing oxygen and hydrogen gases at high temperature c. Identifying the organisms that live in a liter of healthy soil d. Designing and building an artificial heart for the human circulatory system

The correct answer is - d. Designing and building an artificial heart for the human circulatory system.

Explanation:

Engineers have various types of the field according to their skill and knowledge, bioengineers are also one of them, who design biomedical equipment and devices, artificial organs, or technical help in the biological field such as Designing and building an artificial heart for the human circulatory system.

Thus, the correct answer would be d. Designing and building an artificial heart for the human circulatory system.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
