The British scientist Ernest Rutherford postulated the nuclear model of the atom in the early 1900s. He described his model as the atom being mostly empty space with electrons having a fixed orbit around the positively charged nucleus of the atom. The experiment he conducted to arrive at the model is known as the thin-foil experiment. He passed a narrow beam of particles through a thin film of metal foil and observed that the particles were only slightly scattered. It was with this observation that he concluded that most of the mass of a particle is concentrated only in a minute fraction of the total volume of the atom.

In which medium does sound travel the slowest?
ZanzabumX [31]
Sound actually travels slower in air.This is because sound is kinetic energy and has to pass from molecule to molecule.In gas the molecules are farther apart taking more time for it to pass,in water the molecules are closer so it takes less time for the sound to get from one molecule to another and with cast iron (since it's very dense) the molecules are very close allowing sound to travel quickly with ease.

Select the true statements about protein secondary structure.
netineya [11]

Answer:

The α‑helix is held together by hydrogen bonds between the amide N−H and C=O groups.

Disulfide bonds stabilize secondary structure.

Explanation:

Proteins have primary, secondary, tertiary and quartinary structures.

The secondary structure of a protein is the regular, recurring sequence of amino acid in a polypeptide chain. Secondary structure of proteins give rise to the folding observed in the structure of a protein.

The major secondary structures of a protein are α-helices and β-structures.
