Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
Explanation:
u will get 10 out of 6
The anterior, middle, and posterior.
Hypothesis: If plants are placed in white light, then the will grow better than plants in other colours of light.
Independent variable: Colour of light.
Dependent variable: plant growth.
Control group: the plant in the closet.
Experimental group: the plant is the other light colours.
Constants: miracle grow and amount of water.
Measurements: height of plants.
Answer: The object is accelerating in the downward direction.
Explanation: In the given block diagram, there are 4 forces acting on the object.
- The force which is acting on the right side of the object gets cancelled out by the force acting on the left side. Net force on the horizontal line = (100N - 100N) = 0 N.
- The force acting in the downward direction is more than the force acting on the upward direction. Net force on the vertical line = (720N - 600N) = 120N
We know that,
The object moves in the direction of the net force and here, the net force is acting in the downward direction.
And, F = ma
Acceleration will be in the direction of the force only. Hence, the object will be accelerating in the downward direction.
Answer:
D. The process requires energy that is provided by ATP.
Explanation:
Neurons use a pump called the sodium-potassium pump, which normally pumps sodium ions out of the cell and pumps potassium ions into the cell.
This pump goes against the concentration gradient to create the resting membrane potential.
Since the pump goes against the concentration gradient, it requires energy, because it is not passive diffusion.
So, D is the correct answer, as the process requires ATP energy.
