Answer:
The correct answer will be option-E
Explanation:
The neuron is the functional unit of the nervous system which transmits the signals to and fro the tissue and nervous system. The neurons transmit the signals in the form of an electrical impulse as a result of the movement of the ions across the neuron.
When a neuron does not transmit any signal therefore it is known to be at rest but at rest, the movement of ions takes place but very slowly. The movement ions lead to the accumulation of sodium ions inside than outside whereas potassium ions are concentrated outside as compared to inner.
This charge difference leads to the disequilibrium in the charges and hence a potential gradient is created. This potential is known as resting potential.
Thus, option-E is the correct answer.
The answer is; SET B
Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up into globules so they don’t interact with water.
Well, when the cell membrane is in 'hypnotic' mode, it causes it to press against the cell wall, making the cell turgid.
<span>Plant cells will also change with the degree of specialization. It means that when is is a higher developed organism then it will have a higher degree of specialization. For the second question,Somatic cells of animal callus are most common to the plant cell. It is because just like a callus, the tissue of the plant cells are thick and it serves them as protection from friction.</span>
Muscles are in pairs called "antagonistic muscles." Let's take the human elbow joint as an example from the diagram. The elbow joint has 2 muscles; triceps and biceps. These 2 muscles help raise your forearm up or down. In the diagram, it shows an arrow going up which represents that your forearm is being raised. To raise, your biceps contract and your triceps relax. Its the opposite when you lower yopur forearm. To lower, your biceps relax and your triceps contract.
Best of Luck!
