Answer:

rain and turns

Explanation:

There are various confounding variables that could contribute to the speed of the track, one of which is rain. Rain is something that the race teams and officials cannot control and affects the speed at which racecars can operate on a track. This is because the Rain wets the tracks which prevents the cars wheels from properly gripping the track and instead causes them to skid. Another confounding variable would be turns. A track that has more turns would drastically decrease the speed of the tracks as cars would need to slow down for each turn.

solong [7]

Answer:

True, by active transport

Explanation:

The influx and efflux of molecules through the cell membrane depend on the concentration gradient.

When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.

When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.

In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
