Water is attracted to ions, such as sodium, potassium, phosphate, and chloride ions. Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of potassium and phosphate ions. Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.

I just took the quiz on k12
Resonance is the quality of the voice that is produced from sound vibrations in the pharyngeal, oral, and nasal cavities.
Hope this helped, have a great day! :D
Answer:
pesticides are in the form of insecticides,fungicides,herbicides plant growth regulators and so on
Explanation:
Pesticides are lethal to target pests but not to the non-target pests it includes humans as well. The application of pesticides brings gain to the farmers by getting higher yields for better and protected crops. Insecticides act against insects growth, herbicides protects herbs, weeds from its pests, rodenticides protects from rats,avicides protects birds fungicides act against fungi and nematicides act against nematodes. Pesticides are divided according to their types.To protect some plant and animals population which can withstand with pesticides environment.
Answer:
Hyperpolarization means that the membrane potential becomes more negative than the resting potential.
Explanation:
The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.
When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.
