The volume of a gas is dependent on:
1. Pressure
2. Temperature
3. Amount of gas.
Answer: The correct answer is E.
Explanation:
The path for the ejaculation of the sperm starts in the testicles, more exactly in the seminiferous tubules, then the path continues trough the epididymis for reaching vas deferens. Finally, the path is completed by the sperm passing through the ejaculatory duct for being released by the urethra.
Therefore the correct answer is E.
Answer:
species originate through allopatric speciation:
Have a good day! :)
Answer:
C. Hydrogen Ions.
Explanation:
The pH level of soils is measured based upon the acidity or basicity level in the soil. The pH scale usually measures between 0-14. 7 is the neutral pH level of soil and a pH level below 7 is considered acidic and above 7 is alkaline.
So, soil with a high amount of hydrogen ions (H+) will be considered acidic. As the amount of hydrogen ions increases in the soil, the pH level of the soil decreases, making it acidic.
Therefore, option C is correct.
Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.
