<span>Sodium pumps and potassium pumps will not be triggered to open or close therefore causing the cell to remain at electrochemical equilibrium (-70 mv) so there will be no movement of ATP. Also the phosphates needed to create ATP will be inhibited and with a negative charge the cell will not reach threshold to propagate a reaction along the axon.</span>

Phytoplankton form the base of food webs, but are only present in the upper few hundred meters of the ocean. A number of factors
Ksenya-84 [330]

Answer:

The correct answer is d. Oxygen

Explanation:

Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.  

They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.

As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.

Why are groups of small cells better than one large cell at moving material in
quester [9]

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.
