Answer:
Behavioral responses in organisms require communication between cells, organs, organ systems and whole organisms.
Explanation:
Complete question is:
Behavioral responses in organisms require communication between I. cells II. organs III. organ systems IV. whole organisms.
Options for this question:
- <em>II and IV only.</em>
- <em>I, II, III, and IV.</em>
- <em>II, III, and IV only.</em>
- <em>I, II, and IV only.</em>
The relationship function allows living organisms to respond to various stimuli, which defines their behavior in the face of those stimuli.
The coordination of the response to external and internal stimuli involves the whole organism, from the cellular level to the individual level, so the coordinated response depends on the communication between cells, organs, organ systems and the whole organism (the second option I, II, III and IV).
An external stimulus is received by specific receptors, transmitted through the sensory nerves to the central nervous system, which elaborates a response. This response is conducted to an effector organ so that the individual has an adequate response:
- Cell: Neuron.
- Organs: Brain, effector organ.
- Organ system: central nervous system, muscular or hormonal system.
- Individual: the specific response affects the whole organism.

Answer:
Phase III.
Explanation:
Clinical research includes the different steps to test the particular drugs and its use for the medical treatment. Clinical research is divided into four main phases.
The phase III of the clinical research includes the double blinded study and its clinical trial on the patients. This phase determines the drug safety and efficacy. The therapeutic effect of the drug is tested directly in phase III of the clinical trial.
Thus, the answer is phase III.
Answer:
Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.
Explanation:
It is completely normal to get results that do not support the hypothesis.
If a scientist encounters this, he/she should refine (change) the hypothesis and perform the experiment again.
Hope this helps!
