Answer:
a. Manipulated variable: TEMPERATURE
b. Responding variable: CRICKET CHIRP
c. Controlled variable: Same species of cricket
d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more
Explanation:
Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.
Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.
Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.
Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.
Answer:
Extensive damage to oligodendrocytes in the cns could result in l<u>oss of sensation and motor control.</u>
Explanation:
Oligodendrocytes are presnt in glial cells of Central nervous System which comprises of Brain and spinal cord.They are related to the nerve cells. It provides support by production of glial cell line derived neutrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) or insulin growth factor IGF-1 they reduce ion leakage and decrease the capacitance of the cell membrane. Due to intensive damage of the Oligodendrocytes the motor nerves and other nerves of CNS damages looses it activity.
These are mainly occurred due to peripheral injury or demylinated diseases like multiple sclerosis, leukodystrophies,cerebral plasy and other congential disorders.Some chemicals like fluorouracil causes damage to the oligodendrocytes.
