Answer: Option C

Explanation:

Edward syndrome is also called as trisomy which is a genetic disorder. This disorder is caused due to the third copy of the all the part of the chromosome number 18.

The babies that are born is small and have heart defects. They have overlapping fingers.

The ultrasound cannot detect the problem but the process of amniocentesis can confirm the syndrome.

A student plans to measure the circumference of a balloon at various temperatures to determine how temperature affects the volum
nignag [31]
I think the independent variable is the temperature, while the dependent variable is the size of the balloon. The factor that is held constant is the amount of air in the balloon. An identical balloon kept at the original temperature. Independent variable in an experiment is the variable that the experiment plans to change while the dependent variable is the variable whose value depends on the independent variable.

Once a neuron is stimulated and the membrane potential is depolarized, the depolarized axonal membrane is helped to return to it
Vadim26 [7]

Answer:

Explanation:

The cell membrane separates the cell from the outer environment. The extracellular fluid contains the sodium ions (Na+), chloride ions (Cl-), while intracellular fluid contains potassium (K +) and negative anions.

The potential difference arises when the membrane is selectively permeable to some ions. The resting potential is -70mV.  

When the neurons get excited, the sodium ions start to enter by sodium channels.  

Now there are more positive ions inside the cell membrane. It disturbs the resting potential i.e. -70mV. This stage is known as depolarization.

When the inside environment of the cell is more positively charged, the potassium ions start to move out of the cell. It goes out by the voltage-gated channels. Thus resting stage is maintained and it is known as repolarization.

But the initial stability of the cell membrane has to be maintained. To restore the resting stage, the sodium ions start to move out of the membrane and potassium ions enter into the cells again. This is an active transport and has done by the Na+ - K+ pump. Here 3 sodium ions move out and 2  potassium ions pumped into the cell through the plasma membrane.  

Thus the resting potential regains. The potassium ions come back into the cells against the concentration gradient and ATP provides the energy for this phenomena.
