Question

question 2 (1 point) saved listen which of the following best represents physiology? viewing muscle tissue through a microscope examining the surface of a bone studying how the layers of the skin are organized observing how the heart contracts to pump blood question 3 (1 point) listen which of the following is the correct sequence, going from simplest to most complex, in the levels of structural organization of the human body? cellular level, tissue level, chemical level, organ level, organ system level, organismal level cellular level, chemical level, tissue level, organ system level, organismal level, organ level chemical level, cellular level, tissue level, organ level, organ system level, organismal level cellular level, chemical level, tissue level, organ level, organ system level, organismal level chemical level, tissue level, cellular level, organ system level, organ level, organismal level

Explanation:

Physiology is the study of the functions and activities of living organisms and their parts. Observing how the heart contracts to pump blood is a study of a physiological function. For the levels of structural organization of the human body, the correct order from simplest to most complex is the chemical level (atoms and molecules), cellular level (cells made of chemicals), tissue level (groups of similar cells), organ level (organs made of different tissues), organ - system level (groups of organs working together), and organismal level (the whole organism).

Answer:

Question 2: observing how the heart contracts to pump blood
Question 3: chemical level, cellular level, tissue level, organ level, organ system level, organismal level
