Answer:
<em>The correct option is d) once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.</em>
Explanation:
In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.
Answer:
if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.
Explanation:
As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.
In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.
