Neurotransmitters are the chemical molecules, which help in transfer of the signals from one neuron to another. Inside the neurons, the signals are transferred as electrical signals, but at junction of two neuron, which is known as synapse, the signals are transferred in chemical forms.
These neurotransmitters have a definite shape and are recognized by the receptors present in the receptor site of the succeeding neuron. The neurotransmitters from the synapse binds to the receptor site of the receiving neuron. binding of the neurotransmitter to the receptor causes excitation of the receiving neuron, which also known as postsynaptic neuron.
Hence, Like a key in a lock, the shape of the neurotransmitter must bind with the receptors of the receiving neuron.
The inputs are glucose and oxygen and the outputs are water and carbon dioxide.
Counter current involves blood in the capillaries flowing in the opposite direction to the flow of water flowing over them. Gases diffuse faster from one area to another when the concentration difference between the two areas is at its greatest, as compared to when the concentration difference is low.
Answer:
Gain weight
Explanation:
Data provided in the question
Average energy expenditure = 1,800 calories
Average of calories per day = 2,949
Based on the above information, the judgment is as follows
As we can see that she consumes 2,949 calories per day and her energy expenditure 1,800 calories for 3 days
Plus she should gain as
= 2,949 calories - 1,800 calories
= 1,149 calories
So by this explanation, she definitely gains the weight
