You can take two liquids of different densities (how much mass is in a given volume) and pour them into a funnel. An example is oil and water. When the mixture settles, the denser liquid will be at the bottom, and drips through the funnel first. This is a separation that you can just let occur naturally.

Would the water in a pond or the water in a full bathtub have more thermal energy? Explain why.

Mekhanik [1.2K]

Thermal energy is defined as the total kinetic energy of all particles in an object. Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup.

Do plasmids have an importance beyond the practice of genetic engineering?

kozerog [31]

Answer: Yes

Explanation: Plasmids offer a number of unique characteristics that make genetic engineering much more efficient. Plasmids are a type of non-chromosomal DNA. Integrating DNA into a bacterial or other chromosome is far more complex than simply putting DNA into a cell; plasmids make it easier to transport DNA into a cell by eliminating this step.

Which polyatomic ion is found in the compound represented by the formula NaHCO3?

stiv31 [10]

Answer: The correct option is 2.

Explanation: Polyatomic ions are defined as the ions in which two or more elements are covalently bonded to act as a single unit. They always carry some charge.

Examples of polyatomic ions are: $OH^-$ known as hydroxide ion, $SO_4^{2-}$ known as sulfate ion

We are given a compound $NaHCO_3$ having 2 ions which are $Na^+$ and $HCO_3^-$ . these ions are named as sodium ions and hydrogen carbonate ions.

Therefore, the correct option is 2.
