Movement of minerals in plant
Explanation:
In Biology, Active transport means Movement of molecules from lower concentration to Higher concentration through a membranous substance.
It is clearly shown in transportation of minerals from root hairs to root cells.
From root hairs( Lower concentration) minerals are transported to other parts of plant ( Higher concentration, Active transport takes place.
It is clearly evident that in this natural process active transport of minerals takes place effectively through root hairs to various parts of plant.
Answer:
The right sphere is negatively charged, the left sphere is charged positively.
Explanation:
When a negatively charged rod is held above the top of left sphere, the rod will attract positive charges and repel negative charges. As the sphere are initially touching each other so positive charges from the both spheres will moves toward the rod. When we separate the spheres positive charges from right sphere have already moved toward the rod i.e. left sphere, creating a deficiency of positive charges in the right sphere and excessiveness of positive charges in left sphere , hence the right sphere will remain negatively charged and left sphere will remain positively charged.
We know from the physics class that the time is simply the
distance divided by velocity:
time = distance / velocity
Substituting the given values and calculating for time:
time = 360 km / (72 km / hour)
time = 5 hours
<span>Therefore it takes the train 5 hours to arrive.</span>
