In order to maintain homeostasis, cells must be able to i. move from place to place ii. extract energy from food iii. regenerate if they burst iv. get rid of waste a. i and ii only b. ii and iv only c. i, ii, and iv only d. ii, iii, and iv only

B. II and IV only

Explanation:

Homeostasis is the maintenance of the internal environment with respect to the external environment. Therefore, locomotion and regeneration are not the criteria for homeostasis. The most important criteria of homeostasis are how a cell can maintain its energy demands as well as get rid of wastes to do metabolic functioning. If a cell cannot get energy from food, it can not survive. Likewise, if a cell cannot get rid of its waste, it will pile up inside and cause cell toxicity.  

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.
