Tamiku [17]

Answer:

I'd say ALL OF THE ABOVE.

A Mechanical wave is a disturbance that transfers energy as it moves through a medium without displacement of the medium itself.

It can Either be Transversal or Longitudinal.

It is Transversal when the particles of the medium move perpendicular to the wave motion.

It requires a medium and begin at a source with a disturbance

So

ALL THE OPTIONS SEEM LEGIT.

Triss [41]

The question is incomplete, the complete question is;

The lightest particle among the following is:

• Electron •Proton • Neutron • Alpha​

Answer:

Electron

Explanation:

There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.

However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.

Which amino acid chain will be formed by the codons shown below? aag aga ugu?
notsponge [240]
The amino acid chain will be; Lysine-Arginine-Cysteine 
Amino acids are the building block of proteins, many amino acid molecules make up polypeptide chains which form proteins. Each amino acid is coded by a specific codon during the process of translation. A codon consists of three nucleotide bases. In this case AAG codes for amino acid Lysine, while AGA codes for Arginine and UGU codes for amino acid Cysteine.

Compare the distance between the molecules of a gas in a very small container with the distance between the molecules of the sam
kvv77 [185]
Gases take the shape of their container. When you have a large container, the spaces between molecules (particles) can be further apart than if they were close together. In small containers, the particles are forced to be closer together, or compressed.

Think of it like a pep rally in a gym v.s. a classroom. In the gym, everyone has a bit of wiggle room. With the same number of people in a classroom, everyone would need to be packed in there. This can also explain why a smaller pot over boils from steam before a larger one does, even if the amount of water is the same.
