Answer:
Explanation:
Multiple anterior rootlets arise from the spinal cord and merge to form a single anterior root. which contains Anterior roots contain motor axons only.
These axons arise from cell bodies in the anterior and lateral horns of the spinal cord.
Posterior rootlets arise from a single posterior root,which contains sensory axons only.
The cell bodies of these neurons are located in a posterior root ganglion , which is within the posterior root. Each anterior root and its corresponding posterior root unite within the intervertebral foramen to become a spinal nerve.
The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
3.Even though there are some dna traces in the mitochondria,it’s won’t really be tested for gcse and mostly the DNAs are found in the nucleus of the cell.
