Answer:
The correct answer is Active transport moves substances against the concentration gradient.
Explanation:
The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.
In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.
On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.

Explanation:
Lotka‒Volterra dynamic is a kind of dynamic which shows the interaction between two organisms i. e. one is predator and the other is prey. Populations of both organisms are dependent on each other. If one population is increased the other organism population will be reduced due to more feeding. Rabbit population grows double than it is reduced due to feeding by foxes. Decrease occurs in the population of foxes due to death which increases the population of rabbit in that ecosystem.
1) heat flows from hot to cold. the heat from the fire is let off from the exothermic reaction of the fire and warms up the surroundings, including yourself.
2) food is cooked in the oven by heat transfer. the heat warms up the pan and thru conduction, the food is heated and cooked.
3) I'm guessing this question is y it heats up? the answer to that is that the heat waves from the sun is absorbed into the car from radiation and thru convection the whole car is heated
