Match the mixture with the substance// I really need help on this guys (it’s a pic btw)
koban [17]

Answer:

See below  

Step-by-step explanation:

1. Colloid

B) Microscopic insoluble particles that are suspended throughout another substance.

Milk is a colloid. It consists of small fat globules suspended in water.

2. Emulsion

D) Two or more liquids that are not normally mixable.

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.

3. Solution

A) A solute that is evenly distributed within the solvent.

Sugar syrup is a solution of sugar in water.

4)Homogeneous

C) A mixture that has its components distributed evenly within the substance.

A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.

When might a galaxy appear redshifted and why?
mylen [45]

Redshift is said to be experienced when the light or any other electromagnetic radiations from an object undergo an increase in the wavelength but it does not mean that the light literally becomes red.

Redshift occurs due to the expansion of space. It means the farther away the galaxy is from us, the more space it has expanded in the time.

Because as the light left the galaxy, more of the light has been stretched and so more redshifted the light is.
