Explain how the resting potential is created and maintained. (sodium potassium pump) What happens when sodium comes in and potas
MAVERICK [17]

Answer:

The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.

Explanation:

The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.

When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.

Camouflage helps predators to survive by hiding them from what
Alborosie

Answer:

Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey. ...

The GO is a stage outside of the cell cycle commonly referred to as the "resting stage" because
Liono4ka [1.6K]

Answer:

G₀ being a stage of the cell cycle that is the resting stage, where there is no cell division, the cells that would remain in the G₀ stage throughout life are the neurons (option c).

Explanation:

In the G₀ phase, considered outside the cell cycle, there is cell metabolic activity but no cell division, since cyclins and cyclin-dependent kinases disappear. Some cells, such as neurons, do not undergo cell division throughout the life of an organism, so they remain in G₀.

In some organs, such as the liver, the hepatocyte may remain in G₀ until the organ receives an injury, and may regenerate by cell division. This is not the case of neurons, which maintain a constant quantity throughout life.

The other options are not correct because:

<em>     a. </em><em><u>Cancer cells</u></em><em> are characterized by a very active and uncontrolled cell division process.</em>

<em>     b. </em><em><u>Liver cells</u></em><em> can remain in G₀, but cell division can be activated when required.</em>

<em>     d. </em><em><u>Epithelial cells</u></em><em> are constantly dividing, since it is a tissue that undergoes frequent cell replacement.</em>
