Active transport is the moving of molecules across the membrane of the cell against the concentration gradient with the use of ATP.
Low to high concentration. Concentration gradient is the diffusion (movement of molecules from regions of low concentration) from high to low with the gradient. Active transport is from low to high, against the gradient.

Answer:
Orange, blue
Explanation:
A way to determine the color of a compound is using the Crystal Field Theory (CFT), which depends on the wavelengths of the electromagnetic spectrum.
The spectrum is formed by different wavelengths, each one with a color. The color happens when the electron is excited, and the goes from a higher level. When it returns to its original energetic level, it releases a photon, in a color way.
So, in CFT, the substance is placed in a light with a mixture of colors. The photon will absorb the color of its wavelength and will reflect the other color, which will be seen in the solution. In this case, the mixed light was prepared with blue and orange colors.
Then, the Cu(H₂O)₆²⁺ ions will absorb the orange color, and reflect the blue one, and the solution will be blue. The beta-carotene will absorb the blue color and will reflect the orange, so the solution will be orange.
Answer:
The 3 main parts of an electric circuit and their functions are:
Power source - Either electrical or battery, provides the power to the load.
Conducting path - The wires, carry the power from the power source to the load
Load - The device using the electricity such as a computer, light bulb, power saw, etc. More complicated circuits use switches, such as light switches, to control the flow of electricity.
