Answer: b. it takes time for signals to travel all the way to the brain.
Reflex reaction is the instantaneous reaction of the body to the applied external stimuli. This mechanism is present in the body to make it possible to quickly react to situations without putting much effort into thinking and processing the nature of the stimuli. The reflex arc does not include the brain. This is because the brain has to receive signal from the sensory organs through sensory neurons, process it, and send a signal through the motor neuron to the muscles to generate a response. The whole process is time taking and lowers the reaction time of the organism, which can be dangerous in certain situations.
Species A and B because there are no two specific species that do this

Answer:
The correct answer would be -
1. the ocean have
2. water
3. acidic.
Explanation:
Carbon dioxide fro the atmosphere dissolves in the seawater naturally. This process can be understood by the following process:
Water and carbon dioxide reacts to form carbonic acid that can dissociate into either carbonate ion or bicarbonate ion:
1. CO2 + H2O ====> H2CO3⁻ (carbonic acid)
2. H2CO3⁻ ======> H⁺ + HCO3⁻ (bicarbonate ion)
3. H2CO3⁻ ======> 2H⁺ + CO3⁻ (carbonate ion)
Due to the presence of proton ions in seawater, seawater becomes more acidic. As hydrogen ions bind to the carbonate ions to make bicarbonate ions, the carbonate ion reduced which is required to form the
