Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
Probability = number of possible outcomes / total number of outcomes
Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
Air enters into the body through nose and proceeds to pharynx or windpipe afterwards it proceeds down and reaches to larynx the voice box and continue to proceed to trachea which is surrounded by rings so that by air pressure it cannot be collapse from there a divides into two side left and right bronchus then it conducted towards bronchioles which is the pathway to alveoli at last it reaches to its Final Destination (not that movie....hahah) which is alveoli where the exchange of gases takes place
