In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.——————Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.
Answer:
The correct answer is False
Karyotype examination needs to be done at metaphase.
In karyotype test, the examiner is trying to find whether the chromosome is having any abnormality. In metaphase, the chromosome is easier to count and observed.
A chemical (<span>colchicine) will be given to make the cells stuck at metaphase. </span>
Answer:
The responding (dependent) variable
Explanation:
In an experiment, one of the variables is either changed/maipulated or measured. The variable that is deliberately changed is called the INDEPENDENT VARIABLE while the variable that responds to the changes made to the independent variable, or is being measured is called DEPENDENT VARIABLE.
Hence, in the experiment involving the height of the ramp and the speed of the skateboard, the SPEED OF THE SKATEBOARD IS THE DEPENDENT/RESPONDING VARIABLE because it is the variable being measured.
