I found the rest of the exercise on the internet and these are the options.
"-Undifferentiated vertebrae throughout the body.
-One neck vertebra allowing up and down movement.
-Many neck vertebrae that allow for greater mobility.
<span>-Two neck vertebrae allowing up and down and sideways movement."

The correct answer would be the third. - "</span>Many neck vertebrae that allow for greater mobility." The <span>present-day organism with four limbs has a neck with several vertebrae that allow movements of rotation (mostly because of only two vertebrae at the top of the neck), and side way movements, as well as back and forth movements.</span>

Based on what you know about matter explain why the food coloring mixes at different rates
emmasim [6.3K]

Answer:

Matter has different densities. Different food colorings have different densities. Those with a higher density will sink to the bottom and mix much easier than one with a lower density. The higher density also contains more particles making it easier to mix or give it a fuller color.

The equilibrium constant for the gas phase reaction
stellarik [79]
The equilibrium constant is found by [product]/[reactant]

If the equilibrium constant is very small, such as 4.20 * 10^-31, then that means at equilibrium there is very little product and a lot of reactant.
And likewise, if there is a lot of product formed, and very little reactant, then the K value will be very large, which tells us that it is predominantly product.

At equilibrium, for any reaction, there will always be some reactant and some product present. There cannot be zero reactant or zero product. Also keep in mind that the equilibrium constant is dependent on temperature.

At equilibrium, for your reaction, it is predominantly reactants.

Which forces are intramolecular and which intermolecular?
xxTIMURxx [149]

On a chilly, humid evening, intermolecular forces enable fog to form. The gaseous water molecules condense as a result of powerful molecular interactions.

What force allows fog formation?

From the south, warm, moist air is brought in, and if there is snow or cool precipitation on the ground, it will come into touch with the warm, moist breezes. The air coming in will cool as a result of this air-ground contact. Dew point rises at that position, leading to high humidity and the formation of fog.

What is molecular interactions?

Interactions between molecules or between atoms without bonds are referred to as molecular interactions. There are three types of molecular interactions: cohesive (attraction between like), adhesive (attraction between unlike), and repulsive forces.
