I would say excretion since that means the process of expelling waste matter.
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s

Answer:
Sodium-Potassium pumps (proteins that help neurons generate electricity) are produced by ribosomes on the rough endoplasmic reticulum (ER).
Explanation:
Sodium-Potassium Pump (NA+/K+):
The Na+/K+ Pump is a transmembrane channel protein, responsible for maintaining the concentration gradient of sodium and potassium ions in the intra and extracellular environment. This is achieve by pumping 3 Na+ outside and 2 K+ inside the cell at the cost of one ATP. In neurons, these channels help in generating an action potential across the cell membrane that gives rise to a nerve impulse.
Production of Transmembrane proteins:
All membranes and their proteins are produced by the ribosomes on the rough ER. The rough endoplasmic reticulum contains the enzymes required for lipid synthesis; and as cell membranes are made of lipids, the ER is the most suitable location for synthesis. Membrane proteins, particularly, transmembrane proteins like the Na+/K+ pump possess hydrophobic surfaces that don't dissolve in the cytoplasm but readily attach to the ER surface from where they can be transported wherever required.
