I believe it’s choice d. It makes the water molecules move faster
Answer:
Currents are physical occurrences or factors that put motion into oceans, making them move back and forth.
Such factors include but may exceed the following:
- Wind
- Variation in water mass densities (this is caused by alterations in temperature and salinity levels)
- Gravity
- Earthquakes or storms
When there is movement in ocean currents, heat, nutrients, water oxygen levels are also affected.

Answer:
8 electrons
Explanation:
Magnesium is present on group 2.
It has 2 valence electrons.
Electronic configuration of magnesium:
Mg₁₂ = 1s² 2s² 2p⁶ 3s²
1st energy level contain 2 electrons.(1s²)
2nd energy level contain 8 electrons. (2s² 2p⁶)
3rd energy level contain 2 electrons. (3s²)
3rs energy level of magnesium is called valence shell. It contain two valance electrons. Magnesium can easily donate its two valance electrons and get stable electronic configuration.
It react with halogens and form salt. For example,
Mg + Cl₂ → MgCl₂
Answer:
Explanation:
Combustion releases energy in a single step in the form of light and heat. Whereas in respiration, energy is released in steps and is stored in the form of ATP.
