Which dosage form is a semisolid preparation that contains very small solid particles that are suspended in a liquid

1 answer:

4 0

A GEL is a semisolid preparation that contains very small solid particles that are suspended in a liquid. A gel always contains an agent (e.g., agarose) that provides stiffness to the preparation.

A gel is a semisolid preparation that contains a gelling agent which provides stiffness to the preparation.

The gelling agent can be, for example, agarose (this gelling agent is used to prepare gels in electrophoresis).

In an agarose gel, agarose molecules are organized into three-dimensional (3D) structures similar to pores, which allow the passage of DNA fragments during electrophoresis.

Answer:

Ions are atoms that have either gain or lose electrons from the neutral atom.

A loss of electrons results in a positive ion, called a cation, a gain of electron results in a negative ion called an anion.

Ionic compounds are formed by the combination of a cation and anion, or metal + nonmetal.

When naming ionic compounds, name the cation first, and the anion second, changing the ending to ide.

Which of the following best describes how wireless telephones are able to receive and produce sound from one person to another?

alina1380 [7]

Electromagnetic waves are received and then vibrate a speaker which produces sound waves.

Explanation:

The telephone has a receiver-transducer component that can receive electromagnetic wave - radio waves spectrum- and transform them into electric energy. This electric energy is then transformed into sound energy by a speaker. This is how we're able to listen to a phone call.

The opposite happens when we speak on the phone. The sound energy is transformed into electric energy by a microphone – the reverse of a speaker. The transducer now changes the electric energy into electromagnetic waves that travel through space to the recipient in the phone conversation.

Len [333]

Answer:

i added this table for some help

Explanation:

here are some examples

metals:They are hard and shiny, strong, and easy to shape. They are used for many industrial purposes. This group includes iron, gold, silver, chromium, nickel, and copper, some of which are also noble metals.

non-metals:a chemical element (as boron, carbon, or nitrogen) that lacks the characteristics of a metal and that is able to form anions, acidic oxides, acids, and stable compounds with hydrogen.

metalloids:Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. Metalloids have mixed properties which are difficult to characterize.
