Rainwater can replace or replenish freshwater sources.
Precipitation, such as rainwater, is the source of freshwater on Earth.
When the amount of surface freshwater increases, so does the amount of groundwater.
Human activity, such as taking a bath, may change the quality of a freshwater resource. :)
Answer:
Cysteine
Explanation:
<u>Determine the Amino acid that is primarily involved in Binding </u>
The Amino acid that is primarily involved in Binding is Cysteine. while the other Amino acid ( i.e. Histidine ) will be involved in Catalysis.
since the enzyme is functional at pH 6 to 8. and Cysteine has a pH of 5, it should be deprotonated and used primarily for Binding .
Answer:
1. Nerve impulse
2. Neurons
Explanation:
Neurotransmitters are compounds with low molecular weight. They are secreted by axon terminals of the neurons. The released neurotransmitters then bind to the receptors located on next neuron or on the surface of muscle cell.
The function of neurotransmitters is to carry the nerve impulse from presynaptic neuron to the postsynaptic neuron or from neurons to the effector organs such as muscles and glands.
For example, neurotransmitters are released into the synaptic cleft to transmit the nerve impulse between neurons.
