Answer:
Option B, yellow stars
Explanation:
The different range of temperature and the color associated with the stars are as follows - Star with temperature between 5 to 6 thousand kelvin are yellow in color . A star of blue color has a temperature between 30 to 40 thousand kelvin, while a star that has a temperature between 10 to 30 thousand kelvin appears blue white in color. A star appears white when it has a temperature between 7 to 10 Kelvin . A star has red color when its temperature is less than 3.5 thousand kelvin.
Hence, option B is correct.
Answer:
The correct answer will be true.
Explanation:
Myelin is a protective and insulating layer formed around the neurons of the central and peripheral neurons. The Schwann cells in the PNS and oligodendrocytes in the CNS form the myelin sheath around the neurons.
This myelin protects the axons of the neurons as well insulate the neurons which speed up the transmission of the electrical impulse generated in the neurons. If myelin is damaged, these impulses get slow or get damaged.
Thus, true is the correct answer.
The correct answer is: dependent variable.
There are two main variables in an experiment: the independent and dependent variable.
The experimenter changes the independent variable and that has the influence on dependent variable. So, the effect on the dependent variable is tested (observed and recorded).
