Hi there!
Active Transport - Through the use of ATP, active transport pumps molecules against a particular concentration gradient. Active transport occurs from a low concentration solute and moves to a high concentration of solute. Two examples of active transport would be endocytosis and exocytosis.
Passive Transport - Active transport is the movement of molecules down a gradient. Unlike passive transport, it goes from high to low concentration and does not require energy (such as cellular energy). Some examples would be osmosis and diffusion.
I hope this helped!
The height is the dependent variable measured by Miriam when she is testing the effect of red-colored light on potato plants (Option B).
<h3>What is the dependent variable?</h3>
The dependent variable can be defined as an experimental variable modified by the condition during an experiment.
Conversely, the independent variable doesn't change across all the experimental procedures.
In conclusion, the height is the dependent variable measured by Miriam when she is testing the effect of red-colored light on potato plants (Option B).

The normal blood pressure of children is <span>96/62 mmHg.
The blood pressure of an injured child decrease depending on its bleeding because the blood pressure depends on two things: Volume of the blood and the systolic ejection force. So when the volume of blood decreases the blood pressure decrease.
Thinks it as a pump with water at home, the less water there is then a less pressure is, and vice versa.
