This active transport mechanism is a sodium-potassium pump.
The sodium potassium pump is a sequence of proteins within the cell membrane. It moves sodium and potassium ions across the cell membrane in a process called facilitated diffusion, or active transport: when ions move against the concentration gradient, or to a highly concentrated region. To do so, the pump needs energy in the form of ATP, which is produced through cellular respiration. Once the pump receives this energy, it is able to maintain the resting potential in a nerve cell.
They help an environment because they create an ecosystem allowing animals to thrive and live a lifecycle with the resources they need.
Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

The correct answer is d. By causing movement of the organism.
Cilia, flagella and pseudopodia are structures used for movement and/or getting food. Cilia and flagella are very similar in structure with the difference in their length (cilia-short flagella-long and how many of them are found on cells (cells usually have hundreds of cilia while cells with flagella usually only have one or two of them). Pseudopodia is a cytoplasmic extension with the same function as cilia and flagella.
