Beyond our own solar system, we have discovered thousands of planetary systems orbiting other stars in the Milky Way.
Explanation: he planets of our solar system—and even some asteroids—hold more than 150 moons in their orbits.

Stimulation of the parasympathetic nervous system results in: Construction of pupils. Decreased heart rate and blood pressure.
Explanation:
If the cytoplasm of a cell is at ph 7, and the mitochondrial matrix is at ph 8, this means that the concentration of H+ ion is tenfold higher in the cytoplasm than in the mitochondrial matrix.
<h3>What is pH?</h3>
pH means the power of hydrogen and it is a measure of the degree of acidity or alkalinity of a solution.
The pH tells us how acidic or alkaline a solution is. It ranges on a scale of 1 - 14.
- pH of 1 - 6 indicates acidity
- pH of 7 indicates neutrality
- pH of 8 - 14 indicates alkalinity
According to this question, the cytoplasm of a cell is at pH 7, and the mitochondrial matrix is at pH 8. This suggests that the concentration of hydrogen ion (H+) ion is tenfold higher in the cytoplasm than in the mitochondrial matrix.
