I think it is C as plants take in Co2 and release oxygen which humans use to breathe.

If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. <span>The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.</span>
The receptor that are receiving persistent neurotransmitters will be in a continuous state of excitation which can be harmful.
<h3>What are neurotransmitters?</h3>
The chemical substances that is mandatory for the transmission of signals in the body is referred to as neurotransmitters.
Any remaining neurotransmitter is subsequently destroyed or reabsorbed into the transmitting neuron.
The receptor that are receiving persistent neurotransmitters will be in a continuous state of excitation which can be harmful.
Thus, it is necessary that the neurotransmitters gets reabsorbed if in excess.
