A substance that can be used or prepared for use as food
Answer:
The correct order would be
Sensory receptors in the arteries detect low oxygen levels.
↓
Sensory neurons generate an impulse.
↓
The central nervous system relays an impulse to certain brain regions.
↓
The brain sends signals through motor neurons.
↓
Isabel's breathing rate increases.
The working of the nervous system can be summarized as:
The receptors receives the stimulus which then send signals to the brain with the help of sensory neurons.
For example, sensory receptors in the arteries detect the low oxygen levels after which sensory neurons send the signals to the brain.
The stimulus or information is processed in a specified region of the brain which then sends the signals to the effector organ via motor neurons.
The action or reaction is generated at the effector site such as an increase in the breathing rate of Isabel in this case.
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
Answer:
Parasympathetic and Sympathetic branches of the autonomic nervous system
Answer:
A pedigree is like a lineage or a recorded ancestry. For example, if a dog has recorded breeding papers it would show you it's pedigree. I hope that helped! :)
